Trying to book ferries or speed boat between

1) Naha/ Tomari wharf to Zamami Port (Queen Zamami 3)
2) Zamami Port to Aharen (Ferry Matsushima)
3) Takashiki to Naha/Tomari wharf by Marine Liner Takashiki

any help how to do this ?

for 2) I have found a flyer with timetable but the shown phone number only answers automatically in Japanese language. They are probably closed now but as the message is only in Japanese I am afraid that also the speaking person will reply in Japanese when present.

thanks for your help

For the third ferry (Tokashiki to Tomari), you can do the reservation online: https://tokashiki-ferry.jp/Senpaku/portal

For the first, I also found a phone number (see this page) but it will also likely be in Japanese. You might want to try contacting the Zamami Tourist Information Centre (the Naha one will likely be busy) and ask if they can help with the phone reservations since you don't speak Japanese. You can find their phone number and email online (here and here).

Edit: which month are you travelling? Reservations are needed for busy seasons but might not be necessary outside of high season.
