Nitoda port is in the larger of the two towns on Tashirojima, aka cat island.
The port has a small information office and public toilets, and the small town is a few minutes walk away. There are cats to greet you from the get-go, so enjoy!
The second port, Odomari, is to the north-east of the island and is a 30-minute walk from Nitoda. It has no shops or cafes and is much smaller.
