From Innoshima to Kamijima by Car Ferry on the Shimanami Kaido: Tateishi Port, Iwagi Bridge, and Iwagi Kyodokan

No boat from a port on the Ehime side that carries cars is listed in the Kamijima pages

The Kamijima Town official page for the route from Imabari Port to Habu Port, Chuo Pier (今治港〜土生港（中央桟橋）) puts the following line before its table. The table covers “passengers and bicycles.”

※ フェリー便の廃止により、車両は乗船できませんのでご注意ください。

Translation: “* Because the ferry service has been discontinued, vehicles cannot board. Please note.”

The Kamijima tourism site describes how to get there by car.

お車でのアクセスは、しまなみ海道の因島もしくは生口島からカーフェリーに乗ってきていただくと、ゆめしま海道（3つの橋）でつながった町内の移動にも便利です。

Translation: “If you come by car, taking a car ferry from Innoshima or Ikuchijima on the Shimanami Kaido is also convenient for getting around the town, which is connected by the Yumeshima Kaido (three bridges).”

In the Kamijima pages, the ports where cars board are not in Ehime. They are on Innoshima or Ikuchijima. You enter the Shimanami Kaido at Imabari IC and take a ferry on Innoshima or Ikuchijima. The Kamijima pages list 3 routes that carry cars (“Carries: passengers, vehicles”).

Route	Port on the island you arrive at	Time (tourism site diagram)	3 m to under 4 m, one way	4 m to under 5 m, one way	Sunday
Ikuna Ferry (生名フェリー), Habu Port, Nagasaki Pier (土生港（長崎桟橋）) to Tateishi Port (立石港)	Ikuna Island	3 minutes	500 yen	630 yen	Trips marked ◇ do not run on Sundays and holidays
Karoto Ferry Kisen (家老渡フェリー汽船), Karoto Port (家老渡港) to Kamiyuge Port (上弓削港)	Yuge Island	5 minutes	900 yen	1,100 yen	No trips on Sundays

The pages were posted on these dates: February 11, 2024 for the Ikuna Ferry, April 1, 2026 for Karoto Ferry Kisen, and September 1, 2026 for Sanko Kisen. The Karoto Ferry Kisen page says “※日曜日及びドック時は全便運休” (all trips are cancelled on Sundays and during dry dock). The Sanko Kisen page says that trips marked ● are cancelled every Sunday. None of the three pages says whether the fare includes the driver.

This article crosses by the Ikuna Ferry. The tourism site tells people coming by car from around Habu Port to use the Ikuna Ferry from Nagasaki Pier, and Ikuna Island, where Tateishi Port is, continues to Iwagi Island by Iwagi Bridge. For Karoto Ferry Kisen, which goes to Yuge Island, and Sanko Kisen, which goes straight to Iwagi Island, only the time, fare, and Sunday cancellations are in the table above.

From Imabari IC to Innoshima-minami IC, a standard car pays 3,920 yen in cash on the Shimanami Kaido

The tourism site’s diagram “By car (via the Shimanami Kaido)” starts from Imabari IC for people coming from the Ehime side. It shows 44 km to Innoshima-minami IC, 4.5 km from Innoshima-minami IC to Nagasaki Pier and 8 km from Innoshima-minami IC to Karoto Port (we enlarged the starting point of the line to check). The JB Honshi Expressway section distance table gives 42.9 km from Imabari to Innoshima-minami, which differs from the 44 km in the diagram.

The standard car fare is at the point where Imabari and Innoshima-minami meet in the JB Honshi Expressway fare table (PDF).

The JB Honshi Expressway ETC fare page says “※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。” (The holiday discount for standard cars and kei cars does not apply during Golden Week, Obon, Silver Week, the year-end and New Year period, and 3-day weekends in fiscal 2026). For the full Shimanami Kaido fares, see Shimanami Kaido tolls. For why the fare table has “-” in many cells, see ICs where the direction you can go is fixed.

About Innoshima-minami IC, JB Honshi Expressway says the following.

今治（四国）方面から、因島へご用の方はここでお降り下さい。

Translation: “If you are coming from the Imabari (Shikoku) side and have business on Innoshima, please exit here.”

因島から四国方面へ行かれる方は、このICから入って下さい。

Translation: “If you are going from Innoshima toward Shikoku, please enter from this IC.”

本州方面へは行けません。

Translation: “You cannot go toward Honshu.”

Innoshima-minami IC is also where you enter when you go back toward Imabari.

On Sunday, October 25, Imabari IC to Innoshima-kita IC is closed from 6:00 to 12:40

A notice on the Kamijima tourism site, dated September 16, 2026, describes the closure for “Cycling Shimanami 2026” (サイクリングしまなみ2026) on Sunday, October 25.

■今治IC⇔因島北IC 上下線　6：00〜12：40（6時間40分）　通行止め

Translation: “Imabari IC to Innoshima-kita IC, both outbound and inbound lanes, 6:00 to 12:40 (6 hours 40 minutes), closed.”

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）または臨時フェリーをご利用ください。

In the JB Honshi Expressway fare table, the ICs run from Imabari in this order: Ikuchijima-kita, Innoshima-minami, Innoshima-kita. Innoshima-minami IC is inside the Imabari IC to Innoshima-kita IC section. The contact is the Imabari local headquarters of the Cycling Shimanami Executive Committee (0898-23-3055, weekdays 9:00 to 17:00).

At Nagasaki Pier, you drive onto the Ikuna Ferry

The tourism site’s access page has a map of the area around Habu Port with this note.

土生港周辺からお車でお越しの際は『長崎桟橋』より『生名フェリー』をご利用ください。

Translation: “If you are coming by car from around Habu Port, please use the ‘Ikuna Ferry’ from ‘Nagasaki Pier’.”

On the map, Habu Port and Nagasaki Pier are separate piers, and the Ikuna Ferry route line starts from Nagasaki Pier. The enlarged map of the Nagasaki Pier entrance shows “Boarding Lane 1 (乗船レーン①)”, “Boarding Lane 2 (乗船レーン②)”, “Boarding Lane 3 (乗船レーン③)”, and “Spare Lane (予備レーン)”, with “Bus Center (バスセンター)” and “Ticket Machine (券売機)” drawn next to them. In the photo on the page, you can read a sign “Ferry Boarding for Kamijima (上島町行きフェリーのりば)” with “(進入口はこの看板前)” (the entrance is in front of this sign) and “駐車禁止” (No Parking).

The same page explains how to board in “Taking a car on the ferry” (車でフェリーに乗る), in three boxes.

待機レーンで並んで待ちます。生名フェリーは券売機で券を事前に購入できます（推奨）。

Translation: “Line up and wait in the waiting lane. For the Ikuna Ferry, you can buy a ticket in advance at the ticket machine (recommended).”

船員の合図で車ごと乗り込みます。車検証の指示は必要ありません。

Translation: “Drive onto the ferry, car and all, when the crew signals. You do not need to show the vehicle inspection certificate.”

船員が回ってきたら車のサイズに応じた料金を支払い（または券を手渡し）ます。

Translation: “When a crew member comes around, pay the fare for the size of your car (or hand over your ticket).”

The fare depends on the length of the car. The car rows on the town’s page are as follows.

Car length	One way	Round trip
Under 3 m	320 yen	600 yen
3 m to under 4 m	500 yen	900 yen
4 m to under 5 m	630 yen	1,150 yen

On the same page, the first trip from Habu Port (Nagasaki Pier) is at 6:15 and the last is at 23:05. From Tateishi Port, the first trip is at 6:00 and the last is at 23:00. From 7:00 to 20:59 there are 3 to 5 trips an hour. A note says “◇は、日曜日・祝日は運休です。なお、繁忙時には臨時便を運航します。” (Trips marked ◇ do not run on Sundays and holidays. Extra trips run at busy times.) The crossing time is “about 3 minutes at sea” (海上約3分). The page was posted on February 11, 2024, which is old, so please check with the ferry company about service on the day you ride.

The rules at Ehime ports, such as the check-in deadline for cars, are collected in Taking a Car on a Ferry from an Ehime Port. The Kamijima page does not give the check-in time at Habu Port or Nagasaki Pier.

From Tateishi Port to Iwagi Bridge, 6 minutes by car

From Ikuna Island, where Tateishi Port is, you cross to Iwagi Island by Iwagi Bridge on the Yumeshima Kaido. The Kamijima tourism site describes the Yumeshima Kaido like this.

信号もトンネルもなく、交通量も少ない海との距離が近いゆめしま海道は、しまなみ海道とは違う魅力で溢れています。

Translation: “With no traffic lights or tunnels, little traffic, and the sea close by, the Yumeshima Kaido is full of a charm different from the Shimanami Kaido.”

Source: ゆめしま海道 | 瀬戸内かみじまトリップ-上島町観光ガイド | 上島町公式観光WEBサイト

The Iwagi Bridge page says it is “the newest bridge, opened on March 20, 2022” (2022年3月20日に開通した最も新しい橋), a cable-stayed bridge with a central span of 475 m, and gives “6 minutes by car from Tateishi Port” (立石港から車で6分). The hours are “you can cross it any time, 24 hours” (24時間いつでも通れます。).

Source: 岩城橋 | 瀬戸内かみじまトリップ-上島町観光ガイド | 上島町公式観光WEBサイト

The wind limit for the bridge is in Ehime Prefecture’s table of advance closure sections. For the 1.5 km of Prefectural Road 338, Iwagi-Yuge Line (県道338号 岩城弓削線), from Ikuna, Kamijima, Ochi District (越智郡上島町生名) to Iwagi, Kamijima, Ochi District (越智郡上島町岩城) (Iwagi Bridge), the hourly rain and continuous rain columns are blank. The other columns are wind of 15 m/s for two-wheeled vehicles, wind of 25 m/s for vehicles, and ice (the table was updated on March 2, 2026). For the rules on days of strong wind or heavy rain, see Roads That Close in Heavy Rain and Typhoons in Ehime.

We could not check the time or the road names from Iwagi Bridge to Iwagi Port on an official page. From the map data, Tateishi Port and Iwagi Port are about 4.6 km apart in a straight line (a calculation, not the distance by road).

The destination is Iwagi Kyodokan, and the summit side of Sekizenzan is closed

The Kamijima tourism site introduces Sekizenzan on Iwagi Island as a cherry blossom spot with more than 3,000 trees. About Sekizenzan, the site’s notice dated July 1, 2026 says the following.

豪雨災害により、岩城島積善山の一部区間が当面の間通行止めとなります。

Translation: “Because of heavy rain damage, a part of Sekizenzan on Iwagi Island will be closed for the time being.”

・町道積善山線（北三叉路から山頂まで）

Translation: “- Town Road Sekizenzan Line (from the North Fork to the summit)”

(7/28追記)高原積善山線（南三叉路から北三叉路まで）については通行可能となりました。

Translation: “(Added July 28) Kogen-Sekizenzan Line (from the South Fork to the North Fork) is now open.”

We have not found a page that says the closure was lifted. So the destination of this article is Iwagi Kyodokan (岩城郷土館), near Iwagi Port. The Kamijima tourism site introduces it like this.

入場は無料です。

Translation: “Admission is free.”

Source: 岩城郷土館 | 瀬戸内かみじまトリップ-上島町観光ガイド | 上島町公式観光WEBサイト

It is open from 9:30 to 16:00. It is closed on Tuesdays, national holidays, and the year-end and New Year period. The contact is the Kamijima Town Board of Education (0897-77-2070).

Iwagi Port Parking has two numbers, 30 spaces and 11 spaces

The pages describe the walk to the museum and the parking in different ways.

Source	To the museum	Parking
Kamijima tourism site, “Iwagi Kyodokan” text	3-minute walk from Iwagi Port	Iwagi Port Parking (30 spaces)
Kamijima tourism site, “Iwagi Kyodokan” table	5-minute walk from Iwagi Port	Not given
Kamijima Town official, “Kamijima Town Iwagi Kyodokan (former Shima Honjin Miura House)”	3-minute walk from Iwagi Port	Iwagi Port Parking (30 spaces)
Kamijima tourism site, “Parking Information”	Not given	Iwagi Port (Tourist Center Parking), 11 spaces

The tourism site’s list says the parking is free and adds “利用可能時間は各施設の営業時間内に限ります。” (Available hours are limited to the business hours of each facility.) The pages do not say which parking lot has 30 spaces and which has 11.

The way back is the Ikuna Ferry from Tateishi Port

On the way back, take the Ikuna Ferry from Tateishi Port to Habu Port (Nagasaki Pier). The last trip from Tateishi Port is at 23:00.

To get back on the Shimanami Kaido, it is 4.5 km from Nagasaki Pier to Innoshima-minami IC (the tourism site’s diagram). To go toward Imabari, you enter at Innoshima-minami IC.

What we could not check

• The road names and turns from Innoshima-minami IC to Nagasaki Pier
• The road names and turns from Tateishi Port to Iwagi Bridge, and from Iwagi Bridge to Iwagi Port
• The current service status of the Ikuna Ferry, and whether the fare includes the driver
• Whether the closure on Sekizenzan has been lifted
• Whether there is another route that carries cars from Imabari Port to Kamijima (we did not find one in the Kamijima pages or in the Shikoku Transport Bureau’s route map)

This article was written only from official pages and map data. We have not driven the route yet. After we drive it, we will add road width and turns.
