Tarai-bune

A tarai-bune (Japanese: たらい舟), or tub-turned boat, is a traditional Japanese fishing boat originally made from half a barrel or large tub.

They were formerly used throughout Western Japan but are now found only on Sado Island where about a hundred are left which are used for collecting abalone and seaweed.

They are still effective close to shore and in the narrow coves formed by earthquakes.
