By ship
Three ferry lines link the island to the mainland:
Niigata-RyÅtsu, the most heavily used lines with departures hourly Jet ferries ¥5,960, 1 hour Car ferries ¥2,060, 2.5 hours
Naoetsu-Ogi, ¥2,060, 2.5 hours, 4-5 daily
Teradomari-Akadomari ¥1,410, 2 hours, 2-3 daily
Services may be increased for festivals and cut back in the winter or in adverse weather. Prices above are for second class. Renting a blanket costs an extra ¥100. The future of the Naoetsu-Ogi and Teradomari-Akadomari services is very uncertain both less and less frequented, and subject to a lot of cancellation in winter. Travelers would be wise to check beforehand that the services are still running.
The jet ferries have only one class. All lines are operated by Sado Kisen (http://www.sadokisen.co.jp/) Japanese only. English timetables are available (http://www.mijintl.com/sa...).
