If you're planning to come to Shiraishi Island and then on to Shikoku, you might be interested in our boat service. Although Shiraishi is very close to Shikoku, there is no ferry to Shikoku from here. To avoid having to take the ferry back to Kasaoka and then a 3 hr. train ride to Shikoku, we can take you from here by boat to Awashima (one hour), and from there you can catch a 15 minute ferry ride to Shikoku.
While you're at Awashima, you might want to stop for a night at Awashima Taro, a great little minshuku with a Japanese style irori for cooking and a stone bath for bathing. There is also a Moooo! Bar II on the beach there, which is a great place to watch the sunset.
