Mount Kuwasaki, Mountain summit in Toyama Prefecture, Japan.

Mount Kuwasaki is a 2,090 m summit of the Tateyama range in the Hida Mountains (Northern Alps), in Toyama city, Toyama Prefecture. It stands somewhat apart from the range's main ridge, west of Mount Tate, and is listed among the 300 Famous Mountains of Japan and the 100 Mountains of Toyama. Trails reach it via Mount Setokura and Mount Ōina from the Tateyama foothills ski areas.

Mount Kuwasaki is linked in local lore to a buried-treasure legend: in 1585, just before the Toyotomi forces attacked, Sassa Narimasa is said to have buried one million ryō of gold in the mountain. A village song about the "seven knots, seven knots" of gold at Kuwasaki preserves the story. The summit lies on the Tateyama Range of the Hida Mountains, and the mountain is listed among Japan's 300 Famous Mountains.

A folktale says the gods of Mount Hakusan and Mount Tate competed with hoes to see whose mountain was taller, and the soil spilled aside became Mount Kuwasaki. Locals also read the weather from the clouds over the mountain, and a village song about the "seven knots, seven knots" of gold at Kuwasaki preserves a buried-treasure legend.

The mountain is best visited during warmer months from spring through fall when trails are dry and safe for hiking. The main trailhead provides parking and basic facilities to help you prepare before starting your climb.

The summit stands at 2,090 m, slightly off the main ridge of the Tateyama range, and offers views of Tateyama, Tsurugi-dake, Oku-Dainichi-dake and Yakushi-dake, plus a look down into the Tateyama caldera. Local people say the clouds around the mountain foretell the weather.
