Tsuruda Dam

The tallest concrete gravity dam in Kyushu

Tsuruda Dam is the tallest concrete gravity dam in Kyushu.
The Sendai river on which the dam is built originates on Mt. Shiragadake (1,417 m) in beautiful valley Kumamoto Prefecture. It passes through the Nishimorokata Basin in Miyazaki Prefecture, enters Kagoshima Prefecture, passes through Yunoo Falls, and flows into Tsuruda Dam from Sogi Falls. Flowing down the Sendai Plain and into the East China Sea, it is one of the largest rivers in Kyushu, with a basin area of 1,600 km² and a length of 137 km.
Tsuruda Dam, located 51 km from the mouth of the Sendai River, is a multipurpose dam built to protect the area downstream of the dam from flooding and to generate electricity using the power of the water stored in Lake Otsuru, the dam’s reservoir.
Completed in March 1966, the dam is a concrete gravity dam 117.5 m tall, with 123 million m³ of water stored in its reservoir.

A 12-year redevelopment project
As a countermeasure against flooding in the Sendai River basin, which was struck by a major flood in July 2006,
the operation of the dam’s storage capacity was changed to allow it to store more floodwater.
At that time, a redevelopment was carried out to dig tunnels inside the dam embankment and
install three discharge gates and two power generation pipes. This work was completed in October 2018 after about 12 years.
An exploration tour led by

Tsuruda Dam Shochu Storage Time Capsule

In Satsuma-cho, where Tsuruda Dam is located, three distilleries make shochu using the famous water from the foothills of Mt. Shibi, and the deep flavor characteristic of sweet potato shochu has long been popular among the locals. Tsuruda Dam is collaborating with a local shochu distillery to prepare a “Tsuruda Dam Shochu Storage Time Capsule Tour”, in which shochu is stored in an inspection gallery inside the dam and kept there until a special anniversary. Experience the magic of having your very own shochu rest in the dam until a family member, partner, child or grandchild’s special day.

Guide to the area and sightseeing

The area around Tsuruda Dam has many must-see sightseeing spots.
Don’t miss the hot springs, leisure attractions, and historical sites nearby.

  • Sogi Power Plant Ruins

    About 9 km upstream from Tsuruda Dam, there is a red brick building that appears only between early summer and autumn.
    This is the remains of a hydroelectric power station built in 1909 to supply power to the Ushio Okuchi gold mine.
    With the construction of the Tsuruta Dam in 1965, it was submerged at the bottom of the reservoir, but it reappears each year from May to September, earning it the nickname of the “phantom power plant”. With its atmosphere right out of an anime, it has become very popular.
