History
Nakanoho Dam is a relatively modern structure: construction began in 1990 and, fifteen years later, was completed in 2005. It is a sturdy gravity concrete dam, 41.7 meters high with a crest length of 390 meters. Serving the roles of flood control and water supply, it was built as a facility that supports the safety and daily life of the region. With a fairly compact catchment area of about 1.6 square kilometers, it stores water by making the most of the mountain terrain.
Access
The dam lies near latitude 35.53 and longitude 137.34, among the hills of Gifu Prefecture. The surroundings are richly wooded mountain country, an area more easily reached by car than by public transport. It is usual to follow mountain roads toward the dam from the prefecture's main routes; as some stretches have curves and gradients, allow plenty of time when you drive. For details such as parking and whether visits are permitted, please confirm through official sources.
Best season
The reservoir set among the hills is at its most beautiful in the fresh green of early summer and in autumn when the surrounding mountains turn color, both well suited to a drive or a lakeside walk. In winter, roads may ice over or see snowfall, so take care with conditions if you visit. As seasonal viewing rules and event information can change, it is reassuring to check official sources in advance.
