善入寺島

Zen'nyūji Island is a river island in the Yoshino River in Tokushima Prefecture. It stretches about 5 kilometers in length and reaches about 1 kilometer across at its widest point.

Until 1907 the island was densely settled with hundreds of households, villages, schools and shrines. It was then converted into a retention basin and has been uninhabited since.

The island maintains agricultural traditions through seasonal vegetable cultivation, including daikon radishes in winter and watermelons during summer months.

You can reach the island on foot in about an hour starting from a nearby train station. Several walkable bridges provide access, though they may not be passable during high water periods.

The island boundary between two different cities runs directly through its center. This administrative division splits the market district of one city from a district of the other.
