Tomarin is the nickname for the Tomari port building in Tomari, Naha City.

The Tomari port connects Tokashiki, Zamami, Aguni, Tonaki, Kume, Kita-Daito and Minami Daito islands with ferries sailing at least daily. Tomarin has installed not only a ferry tickets center, but also a convenience store, souvenir shop, cafe, restaurant, post office, Rent a car office and a resort hotel on the upper floors.

Many wedding ceremonies are held at the hotel, too, and both the 2^nd and 3^rd floors have outside decks where visitors can take a rest and relax with ocean viewing.
