Lake Towada

Lake Towada is a small lake located on the border between Aomori and Akita prefecture.  It is the largest crater lake on Japan’s main island of Honshū, with a surface area of approximately 62km² and a maximum depth of 327m. Lake Towada sits on top of an “active volcano”. The volcano, although not currently showing major signs of volcanic unrest, eruptions can still happen without warning. There were originally two volcanic calderas, but one collapsed on itself some 5000 years ago, forming one large caldera lake.

The most recent eruption of the volcanic calderas took place in 915AD, which caused havoc on the surrounding region for the following few years. However, in recent years, the lake is used for more recreational purposes, and was stocked with fish in the early 1900’s. Rainbow Trout, Kokanee Salmon (Sockeye Salmon), Carp, Cherry Salmon, and Crucian carp are some of the main species of fish that can be found in the lake. The Oirase River flows from Lake Towado, and as such is a popular fishing place at the river mouth and down the river. 

Scenic cruises can be taken on Lake Tawada, and if you are interested in taking these cruises, make sure you stop in at the local Tourism Center in the township of Yasumiya, which is the only town that can be found around the shores of the lake. It’s found on the southern side of the lake, and is where all the accommodation in around Lake Towada can be found.
