From Matsuyama Airport to Oyamazumi Shrine on Omishima by the Shimanami Kaido, from Imabari-kita IC to Omishima IC

The destination is a shrine on Omishima, at the center of the Shimanami Kaido

Oyamazumi Shrine (大山祇神社) is on Omishima in Imabari, Ehime Prefecture. The shrine’s official site calls Omishima “the center of the Shimanami Kaido, the largest island in the Geiyo Islands.” This article describes the way for a person who rents a car at Matsuyama Airport, enters the Nishiseto Expressway (Shimanami Kaido) at Imabari-kita IC, crosses three bridges, leaves at Omishima IC, and drives to the shrine.

The road from the airport to Imabari overlaps with the article on Matsuyama Airport to Itoyama Park. That article uses the Matsuyama Outer Ring Road and the Matsuyama Expressway, leaves at Imabari Yunoura IC, and drives on National Route 196. This article describes the part after that, inside the Shimanami Kaido.

The official Ehime guide says about 1 hour 50 minutes from the airport to Tatara Shimanami Park

The official Ehime tourism site, Iyokan Net (いよ観ネット), has a guide for going from Matsuyama Airport to the Shimanami Kaido by car. The destination is not the shrine. It is Michi-no-Eki Tatara Shimanami Park, right after you leave Omishima IC.

マイカーをご利用の場合 松山空港～しまなみ海道～道の駅　多々羅しまなみ公園（約1時間50分） 松山空港 県道22号線・183号線、国道196号線 約1時間15分 今治IC しまなみ海道（西瀬戸自動車道） 約30分 大三島IC 国道317号線 約5分 道の駅　多々羅しまなみ公園

Translation: “If you use your own car: Matsuyama Airport to Michi-no-Eki Tatara Shimanami Park via the Shimanami Kaido (about 1 hour 50 minutes). Matsuyama Airport. Prefectural Roads 22 and 183, National Route 196. About 1 hour 15 minutes. Imabari IC. Shimanami Kaido (Nishiseto Expressway). About 30 minutes. Omishima IC. National Route 317. About 5 minutes. Michi-no-Eki Tatara Shimanami Park.”

The local roads in this guide are Prefectural Roads 22 and 183, National Route 196, and National Route 317 after Omishima IC. The only expressway name is the Nishiseto Expressway. The starting point is Matsuyama Airport. The about 1 hour 15 minutes is the time to Imabari IC, and the about 30 minutes is the time from Imabari IC to Omishima IC.

The time to the shrine is written on other pages.

• Imabari City’s tourism information gives about 10 minutes from Omishima IC to Oyamazumi Shrine.
• The shrine’s official site writes “7 km from the Nishiseto Expressway (Shimanami Kaido) [Omishima IC].”
• The model course of Iyokan Net writes “about 13 minutes by car” from Michi-no-Eki Tatara Shimanami Park to Oyamazumi Shrine.

These numbers have different starting points, so we have not added them up. We could not find an official travel time that covers the whole way from Matsuyama Airport to Oyamazumi Shrine.

Imabari IC and Imabari-kita IC, the difference in the entrance

The Ehime guide enters at Imabari IC. This article describes entering at Imabari-kita IC, but Honshu-Shikoku Bridge Expressway Company writes that from either one you can only go toward Honshu. The text of the Imabari-kita IC page is as follows.

今治北ICから今治IC、来島海峡SA及び松山道（松山・高松方面）へは行けません。 （今治北ICから入られるお客様へ） 本四道路をご利用される場合、本州方面にしか行けません。ご注意下さい。

Translation: “From Imabari-kita IC, you cannot go to Imabari IC, Kurushima Kaikyo SA, or the Matsuyama Expressway (toward Matsuyama and Takamatsu). (To customers entering from Imabari-kita IC) If you use the Honshu-Shikoku road, you can only go toward Honshu. Please be careful.”

四国側から来島海峡SAへ行かれる場合は、今治ICから流入し、来島海峡SAへお越し下さい。来島海峡SAは上下一体型のサービスエリアです。 一般道路から今治北ICをご利用いただく場合、来島海峡SAには立ち寄れませんのでご注意下さい。

Translation: “If you go to Kurushima Kaikyo SA from the Shikoku side, please enter from Imabari IC and come to Kurushima Kaikyo SA. Kurushima Kaikyo SA is a service area that combines the inbound and outbound sides. If you use Imabari-kita IC from a local road, you cannot stop at Kurushima Kaikyo SA, so please be careful.”

The Imabari IC page has a guide in the same direction.

（今治ICから入られるお客様へ） 本四道路をご利用される場合、本州方面にしか行けません。ご注意下さい。

Translation: “(To customers entering from Imabari IC) If you use the Honshu-Shikoku road, you can only go toward Honshu. Please be careful.”

Omishima is on the way toward Honshu, so this direction rule does not affect the route. But if you want to rest at Kurushima Kaikyo Service Area before crossing the islands, the rule is that you enter at Imabari IC, not Imabari-kita IC. Kurushima Kaikyo SA is also written about in the Itoyama Park article.

The difference in the distance and tolls from Imabari IC and Imabari-kita IC to Omishima IC is as follows, from the toll table and the section distance table of Honshu-Shikoku Bridge Expressway Company (standard car).

	Imabari IC	Imabari-kita IC
Section distance to Omishima IC	29.9km	24.7km
Cash car (non-ETC car) toll	2,830 yen	2,670 yen
ETC car toll (weekdays)	1,690 yen	1,540 yen
ETC car toll (holidays)	1,340 yen	1,290 yen

We could not find an official guide that describes the route on local roads between Imabari IC and Imabari-kita IC, or from which intersection you turn in to the entrance of Imabari-kita IC. In the map data, Prefectural Road 161 (Itoyama Park Line) passes just west of Imabari-kita IC. The position of the entrance should be checked on the guide signs on site.

The order of the bridges and islands

The “Bridges of the Shimanami Kaido” page of Honshu-Shikoku Bridge Expressway Company lists the bridges in order from the Honshu side. Going from the Imabari side, you cross them in the following order.

Order	Bridge	Bridge length	Where you arrive	IC you can leave at
1	Kurushima Kaikyo Bridge (3 suspension bridges: Third, Second, First)	1,570m, 1,515m, 960m	Oshima	Oshima-minami IC
2	Oshima Bridge (suspension bridge)	840m	Mijikajima	None
3	Hakata Bridge	325m	Hakatajima	Hakatajima IC
4	Omishima Bridge (arch bridge)	328m	Omishima	Omishima IC

About the Kurushima Kaikyo Bridge, Honshu-Shikoku Bridge Expressway Company writes the following.

来島海峡大橋は、大島と今治の間約4kmの来島海峡に架かる総延長4.1kmの3つの吊橋の総称です。

Translation: “The Kurushima Kaikyo Bridge is the collective name of three suspension bridges, with a total length of 4.1 km, that span the Kurushima Strait of about 4 km between Oshima and Imabari.”

Source: 来島海峡大橋｜しまなみ海道

We also checked the order of the bridges in the map data. From the Imabari side, it is the Third Bridge, the Second Bridge, and the First Bridge.

Hakata Bridge and Oshima Bridge are together called the “Hakata-Oshima Bridges.”

伯方・大島大橋は伯方島と見近島の間に架かる伯方橋と、見近島と大島の間に架かる大島大橋を総称したものです。

Translation: “The Hakata-Oshima Bridges is the collective name of the Hakata Bridge between Hakatajima and Mijikajima and the Oshima Bridge between Mijikajima and Oshima.”

Source: 伯方･大島大橋｜しまなみ海道

For the time of opening, the Kurushima Kaikyo Bridge is given as May, Heisei 11 (1999), the Hakata-Oshima Bridges as January 1988, and the Omishima Bridge as May 1979. About the Omishima Bridge, Honshu-Shikoku Bridge Expressway Company writes “本州四国連絡橋の海峡部に架けられた橋としては唯一のアーチ橋です。” (It is the only arch bridge among the bridges built over the straits of the Honshu-Shikoku bridges.)

There are two ICs where you can leave on Oshima. A car coming from the Imabari side leaves at Oshima-minami IC.

今治（四国）方面から、大島へご用の方はここでお降り下さい。 大島から四国方面へ行かれる方は、このICから入ってください。 本州方面へは行けません。

Translation: “People coming from the Imabari (Shikoku) side who have business on Oshima, please leave here. People going from Oshima toward Shikoku, please enter from this IC. You cannot go toward Honshu.”

Oshima-kita IC works in the opposite direction.

尾道（本州）方面から、大島へご用の方はここでお降り下さい。 大島から本州方面へ行かれる方は、このICから入って下さい。 四国方面へは行けません。

Translation: “People coming from the Onomichi (Honshu) side who have business on Oshima, please leave here. People going from Oshima toward Honshu, please enter from this IC. You cannot go toward Shikoku.”

A car going from the Imabari side to Omishima passes Oshima-minami IC, Oshima-kita IC, and Hakatajima IC, and goes on to Omishima IC. The pages of Omishima IC and Hakatajima IC have no note on the direction you can go. This does not mean they say there is no restriction. It means no note is posted.

From Imabari-kita IC to Omishima IC, the toll for a standard car is 1,290 to 2,670 yen

The toll table of Honshu-Shikoku Bridge Expressway Company divides the standard car tolls into three tables. The numbers from Imabari-kita IC to Omishima IC are read from the row for Imabari-kita and the column for Omishima in each table.

How you pay	Title of the table	Toll
Cash	Standard car, cash car (non-ETC car) toll	2,670 yen
ETC (weekdays)	Standard car, ETC car toll (weekdays)	1,540 yen
ETC (holidays)	Standard car, ETC car toll (holidays)	1,290 yen

In the section distance table, Imabari-kita IC to Omishima IC is 24.7 km. Kei cars and similar, medium-sized vehicles, large vehicles, and extra-large vehicles are in separate tables.

There is a condition for the holiday toll. The toll table page of Honshu-Shikoku Bridge Expressway Company has the following note.

※2026年度のゴールデンウイーク、お盆、シルバーウィーク、年末年始、3連休は、普通車・軽自動車等の休日割引が適用されません。 普通車・軽自動車等でETC走行された場合はETC車料金(平日)となります。

Translation: “* In fiscal year 2026, the holiday discount for standard cars, kei cars, and similar vehicles does not apply during Golden Week, Obon, Silver Week, the New Year holidays, and three-day weekends. If a standard car, kei car, or similar vehicle uses ETC, the ETC car toll (weekdays) applies.”

Honshu-Shikoku Bridge Expressway Company tells the applicable days in its notice “Days when the holiday discount applies in fiscal year 2026.” Even if your departure day is a weekend or a public holiday, the weekday toll applies if it falls on a three-day weekend or similar.

From October 19, one-way alternating traffic on Mondays, Wednesdays, and Fridays between Omishima IC and Hakatajima IC

Among the sections where you cross bridges, there is a bridge repair construction restriction between Omishima IC and Hakatajima IC, which includes the Omishima Bridge. This is the content of the notice that Honshu-Shikoku Bridge Expressway Company issued on September 24, 2026.

E76 西瀬戸自動車道 大三島 IC ～ 伯方島 IC(上り・下り)では、橋梁補修工事のため、以下のとおり昼夜連続片側交互通行規制を実施いたします。

Translation: “On the E76 Nishiseto Expressway between Omishima IC and Hakatajima IC (inbound and outbound), because of bridge repair work, one-way alternating traffic restrictions will be carried out day and night as follows.”

昼夜連続片側交互通行規制(各週月曜、水曜、金曜（祝日除く）9 時 00 分～翌 5 時 00 分(予定))を実施いたします。 工事完了まで、走行可能な車線は計１車線(交互通行)のみとなります。 ※規制区間においては、一旦停止及び 50 ㎞/h の速度規制を実施しますので、誘導員の指示に従い安全に走行していただきますようお願いいたします。

As the contact for the construction, the notice lists the Shimanami Imabari Management Center (0898-23-7250, 9:00 to 17:30, except Saturdays, Sundays, and holidays).

On October 25, Imabari IC to Innoshima-kita IC is closed for a cycling event

On Sunday, October 25, 2026, the international cycling event “Cycling Shimanami 2026” is held. The official site of the event writes that the main line of the Nishiseto Expressway will be closed as follows.

「サイクリングしまなみ2026」の開催に伴い、瀬戸内しまなみ海道（西瀬戸自動車道）本線が下記の日時、上下線とも通行止めとなります。

Translation: “Because of the holding of ‘Cycling Shimanami 2026,’ the main line of the Setouchi Shimanami Kaido (Nishiseto Expressway) will be closed in both directions on the following date and time.”

令和8年10月25日（日） ■今治IC⇔因島北IC　上下線　6:00～12:40（6時間40分）　通行止

Translation: “Sunday, October 25, Reiwa 8. ■ Imabari IC <-> Innoshima-kita IC, both directions, 6:00 to 12:40 (6 hours 40 minutes), closed”

Source: 交通規制情報 | サイクリングしまなみ2026　瀬戸内しまなみ海道・国際サイクリング大会

The section from Imabari-kita IC to Omishima IC is inside this closed section. The Q&A of the same page writes the following about the blocking of the entrances and about cars that were already on the expressway before the restriction.

6時から、今治IC～尾道大橋出入口の各IC入口において、車両が進入できないよう封鎖します。ただし、6時までに料金所を通過した車両（本線走行中の車両）は、下り線は今治ICまで走行可能、上り線なら尾道大橋出入口まで走行可能です。（必ずしも直近のICで降りなければならないということはありません。）

Translation: “From 6:00, the entrance of each IC from Imabari IC to the Onomichi Ohashi entrance and exit will be blocked so that vehicles cannot enter. However, vehicles that passed the toll gate before 6:00 (vehicles driving on the main line) can drive as far as Imabari IC on the outbound line, and as far as the Onomichi Ohashi entrance and exit on the inbound line. (You do not necessarily have to leave at the nearest IC.)”

For people who come by car, there is a guide on detours and temporary ferries.

なお、車両をご利用される場合は、迂回路（瀬戸中央自動車道、神戸淡路鳴門自動車道）又は臨時フェリー及び定期フェリーをご利用ください。

Translation: “If you use a vehicle, please use the detours (the Setonaka Expressway and the Kobe-Awaji-Naruto Expressway) or the temporary and regular ferries.”

In the course map of the event, the driving section of Course C is written as “Imabari IC - Omishima IC - Omishima loop - Hirokoji,” and Course F as “Imabari IC - Omishima IC - Hirokoji.” For restrictions on local roads, the event page shows maps for 11 places. They are around Imabari IC, around Kurushima Kaikyo SA, in front of Sunrise Itoyama, around Oshima BS, around Imabari Port, and so on. There was no map that shows local roads on Omishima. It is written that from 12:40, the whole section can be used as usual.

This restriction is only for October 25, 2026.

From Omishima IC to the shrine

When you leave at Omishima IC, Michi-no-Eki Imabari Tatara Shimanami Park (道の駅 今治市多々羅しまなみ公園) is very close. The roadside station information of the Ministry of Land, Infrastructure, Transport and Tourism introduces this roadside station like this.

「道の駅」今治市多々羅しまなみ公園は、大三島IC下車すぐの所にあり、

Translation: “Michi-no-Eki Imabari Tatara Shimanami Park is right by the exit of Omishima IC,”

Source: 道の駅情報｜今治市多々羅しまなみ公園

We could not find an official guide that describes the route to the shrine. The numbers are as follows.

• The shrine’s official site: 7 km from Omishima IC
• Imabari City’s tourism information: Omishima IC -> about 10 minutes -> destination
• The model course of Iyokan Net: about 13 minutes by car from Michi-no-Eki Tatara Shimanami Park

When we tried a route search based on OpenStreetMap from Omishima IC to the shrine’s parking lot, the route went from National Route 317 to Prefectural Road 21 (Omishima-Kamiura Line), and the distance was about 7.9 km. This is different from the official 7 km. A route search is not an official guide, so the signs on site come first.

As a place to rest, the guide of JB Highway Service has Kamiura Parking Area. It writes “上浦PAは、下り線のみにあって、自動販売機コーナーを設置しています。” (Kamiura PA is only on the outbound line and has a vending machine corner.), and the parking capacity is 11 small cars. The event page writes “the outbound line can be driven as far as Imabari IC,” so outbound means the line going toward Imabari. Reading the two together, it seems that the line going from Imabari toward Onomichi does not have Kamiura PA, but we could not confirm the definition of inbound and outbound on the pages of Honshu-Shikoku Bridge Expressway Company.

There are four parking lots. The shrine’s lot beside the torii gate has 13 spaces

The official site of Oyamazumi Shrine describes parking as follows.

自動車 ・西瀬戸自動車道（しまなみ海道）【大三島IC】より７ｋｍ ※駐車場：鳥居脇に１３台駐車可能 その他、大三島藤公園駐車場等利用可

Translation: “By car. 7 km from the Nishiseto Expressway (Shimanami Kaido) [Omishima IC]. * Parking: 13 cars can park beside the torii gate. In addition, the parking lot of Omishima Fuji Park and others can be used.”

Source: アクセス | 【公式】大山祇神社

The parking lots near the shrine are lined up below by source. When the number differs by source, both are written.

Parking lot	Number of spaces	Fee	Source
Beside the torii gate of the shrine	13	Not written on the shrine’s official site	The shrine’s official site, Imabari City
Omishima Fuji Park city parking lot	50	Free	Imabari City (shrine page and Fuji Park page)
Michi-no-Eki Shimanami-no-Eki Mishima	31 (Ministry of Land, Infrastructure, Transport and Tourism), 32 (Michi-no-Eki Liaison Council), 50 (Imabari City)	Free (Imabari City)	Ministry of Land, Infrastructure, Transport and Tourism, Michi-no-Eki Liaison Council, Imabari City
Michi-no-Eki Imabari Tatara Shimanami Park	298 standard cars, 16 large vehicles	Not written	Ministry of Land, Infrastructure, Transport and Tourism

The shrine page of Iyokan Net writes the parking as “Yes (nearby facility) 50 spaces” and the parking fee as “Free.” It says “nearby facility,” and the number is different from the 13 spaces beside the torii gate.

About Michi-no-Eki Shimanami-no-Eki Mishima, the Ministry of Land, Infrastructure, Transport and Tourism writes the following.

駐車場：普通車31台／大型車なし／身障者用1台（24時間利用可能）

Translation: “Parking: 31 standard cars / no large vehicles / 1 for people with disabilities (available 24 hours a day)”

Source: 道の駅情報｜しまなみの駅御島

The opening hours are written as “8:30 to 17:00,” open all year. Imabari City’s tourism information gives the opening hours as “8:30 to 17:00” and writes that a hot shower is “200 yen per use.” The Ministry of Land, Infrastructure, Transport and Tourism writes that this roadside station is “next to Oyamazumi Shrine.”

For Michi-no-Eki Imabari Tatara Shimanami Park, the Ministry of Land, Infrastructure, Transport and Tourism writes “298 standard cars / 16 large vehicles / 3 for people with disabilities / 110 bicycle spaces (available 24 hours a day).” The opening hours differ by source.

• Ministry of Land, Infrastructure, Transport and Tourism: Information center and local products center 9:00 to 17:00 (10:00 to 16:00 in winter), restaurant 11:00 to 15:00 (last order) (11:00 to 14:00 (last order) in winter)
• Model course of Iyokan Net: roadside station 9:00 to 17:00, restaurant 10:00 to 16:00

Visiting is from around sunrise to 17:00. The hours and fee of the Treasure Hall differ by source

The shrine’s official site writes the following about visiting.

開門時間 日の出頃～午後５時 神札授与所 （御札・御守り・御朱印）午前９時～午後５時 ご祈祷受付 午前９時３０分～午後４時

Translation: “Gate opening hours: around sunrise to 17:00. Amulet office (talismans, charms, and goshuin stamps): 9:00 to 17:00. Prayer reception: 9:30 to 16:00.”

Source: ご参拝・ご祈祷のご案内 | 【公式】大山祇神社

Imabari City’s tourism information writes the shrine’s fee as “free” and the sightseeing time as “30 minutes.”

For the opening hours of the Treasure Hall, the numbers differ between two sources.

現在、宝物館の拝観にあたり入館時間を変更しております。 開館時間　午前９時～午後４時３０分（最終入館は午後４時）

Translation: “At present, we have changed the entry times for visiting the Treasure Hall. Opening hours: 9:00 to 16:30 (last entry 16:00).”

Source: 宝物館における拝観時間のお知らせ | 【公式】大山祇神社

The date of this official notice is March 1, 2024. Iyokan Net writes the Treasure Hall and Maritime Museum as “9:00 to 16:00 (entry until 15:30),” open all year. For the admission fee, Iyokan Net writes “adults 1,000 yen / high school and university students 800 yen / elementary and junior high school students 400 yen.” We could not find the admission fee on the shrine’s official site.

The shrine’s official site writes the following about the Treasure Hall.

全国の国宝・国の重要文化財の指定を受けた武具類の約８割が、ここ大山祇神社宝物館に保存展示されています。

Translation: “About 80 percent of the arms and armor designated as National Treasures or Important Cultural Properties of Japan across the country are preserved and displayed here in the Oyamazumi Shrine Treasure Hall.”

Source: 宝物さんぽ | 【公式】大山祇神社

There are also differences by day. The shrine’s official site gives October 19 as the Nukiho Festival, with “all-day prayers suspended.” The Shichi-Go-San period is Tuesday, November 3 (holiday) to Monday, November 23 (holiday), and the Shichi-Go-San reception is from 9:30 to 16:00. The notices do not write changes to the gate opening hours on festival days.

What to check before you leave

• Expressway closures: As of 0:37 on October 13, 2026, the closure information of Honshu-Shikoku Bridge Expressway Company showed “通行止めはありません。” (There are no closures.) for four-wheeled vehicles on the Nishiseto Expressway. Check again on the day you leave.
• Strong wind: The same page says “本四高速道路は、風速によって、四輪車が通行止めにならなくても、二輪車は通行止めになることがあります。” (Depending on the wind speed, the Honshu-Shikoku Expressway may close to two-wheeled vehicles even when it is not closed to four-wheeled vehicles.)
• Opening of the Imabari Asakura IC to Imabari Yunoura IC section: As of October 13, 2026, the page of the Matsuyama River and National Highway Office still shows “令和８年度 開通予定” (scheduled to open in fiscal year Reiwa 8). When it opens, the route from the airport to Imabari will change.
• Bicycles: Where bicycles ride on the Shimanami Kaido, and the rules for passing bicycles by car, are collected in another article.
• Construction and restrictions on local roads: National, prefectural, and city roads publish information differently depending on who manages them. Where to check is collected in this article.

What we could not confirm

• An official page with the car travel time for the whole way from Matsuyama Airport to Oyamazumi Shrine
• The route on local roads between Imabari IC and Imabari-kita IC, and the position of the entrance to Imabari-kita IC
• An official guide on the route from Omishima IC to the shrine (the shrine’s official site goes only as far as “7 km,” and Imabari City “about 10 minutes”)
• The fee of the parking lot beside the shrine’s torii gate
• Construction and closures on local roads on Omishima (we did not check the restriction information for national, prefectural, and city roads)
• The time of day on October 25, 2026, when bicycles ride on the local roads of Omishima during the event

What comes next for this article

The latitude and longitude of the points, and the positions of the bridges and ICs, were checked with OpenStreetMap map data. The point numbers will be the same as the chapter numbers of the driving video. This article was not made from a drive by the operator. It is put together from checking official pages. After we drive the route, we will add how the guide signs appear and where the parking lot entrances are.
