If you cannot speak Japanese, it will be important to bring a phrasebook. Almost all of the native islanders have virtually no comprehension of English. On the other hand, due to the presence of school staff, university students and migrants from the Philippines, there should be one or two English speakers somewhere to be found.
Eriko Yoshizato, the manager of Yoshizato Hotel, speaks good English and will be able to help with any queries.
If you have studied Japanese, you will have a great opportunity to practice the Okinawan dialect and the rarer Hachijo dialect.
