Most travelers will arrive by direct ferry from Kasaoka, which is easily accessible by JR train; it is also possible to come from Shikoku if you are willing to travel on Saturdays and change ferries a few times.
There are two ferry companies serving the route from Kasaoka to Shiraishi. The more useful of the two is operated by Sanyo Kisen (三洋汽船), and departs most frequently. The path from the train station to the Sanyo Kisen ferry terminal is well signed in English and takes less than ten minutes to walk.
Although this ferry does not carry cars, free parking is available in the summer months near their terminal. There is generally no reason to take a car to Shiraishi; the island can be walked from end to end in an hour or less.
The Sanyo Kisen ferry timetable is also available in English from the official website.
Sanyo Kisen also operates a car ferry, but it leaves from a different port.
The island is quite small—about six kilometers in circumference. This makes it easy to get around on foot or by bicycle. There is no public transportation on the island.

Summertime visitors enjoy the island's sand beaches and the views out on the Inland Sea.

This is Western style accommodation with a shared bathroom, toilets, and kitchen. Japanese style accommodation is available along the beach.
