How to get to Iwaishima

Based on the timetable and fare table (revised Oct 1, 2019, PDF) on Kaminoseki Town's "Island Routes" page. The page was posted Aug 12, 2025. Operated by Kaminoseki Koun Co., Ltd. (scheduled boat Iwai, tel. 0820-62-0102). Calling order: Yanai Port – Murotsu – Kaminoseki – Kamai – Shidai – Iwaishima. The boat may be unable to enter Shidai Port and Kamai Port depending on the weather. Boarding procedures are required, so be at the port at least 10 minutes before departure (procedures may close shortly before departure). All sailings are suspended on Jan 1 (normal service from Jan 2). The town directs passengers to Kaminoseki Koun's official Facebook for service status. Child fares are about half the adult fare (in brackets in the table). From Yanai Port there are 2 sailings, 9:30 (arr. Iwaishima 10:40) and 15:45 (arr. Iwaishima 16:55), calling at Murotsu, Kaminoseki, Kamai and Shidai. Only 2 sailings go from Iwaishima all the way to Yanai Port: 6:45 (arr. Yanai Port 7:55) and 12:30 (arr. 13:40). The 3rd sailing at 17:05 ends at Murotsu (arr. 17:45) and does not go to Yanai Port. Yanai Port ⇔ Iwaishima fares: adult ¥1,610, child ¥810. The town's Iwaishima sightseeing pamphlet also says "70 minutes, 3 sailings a day (2 a day call at Yanai Port)". The town's "Access" page gives Yanai Port ⇒ Kaminoseki as "about 35 minutes, ¥860", but the fare table in the timetable PDF gives Yanai Port ⇔ Kaminoseki as ¥880, so they do not match. The town's official pages do not say whether cars can be carried.

Child fares are about half the adult fare (in brackets in the table). From Murotsu Port there are 3 sailings: 6:10 (arr. Iwaishima 6:38, direct), 10:00 (arr. 10:40) and 16:15 (arr. 16:55). From Kaminoseki (ferry landing) you can board 2 of them, at 10:05 and 16:20 (the 1st sailing does not call at Kaminoseki). The fare to Iwaishima from either is adult ¥930, child ¥470. From Iwaishima there are 3 sailings, 6:45, 12:30 and 17:05, arriving at Kaminoseki at 7:20 / 13:05 / 17:40 and at Murotsu at 7:25 / 13:10 / 17:45. The town warns that the ferry landing behind Michi-no-Eki Kaminoseki Kaikyo is Murotsu Port, so passengers do not board at the wrong place. The town's Iwaishima sightseeing pamphlet says "40 minutes from Murotsu, which has parking". The town's cultural properties page says "by scheduled boat (3 sailings a day) from the Murotsu ferry landing to Iwaishima Port (about 40 minutes)". The town's official pages do not say whether cars can be carried.
