Mount Tōgū, Mountain summit in Tokushima Prefecture, Japan.

Mount Tōgū rises to roughly 1,090 meters and is covered with dense forest, with several hiking routes crossing its slopes. The trails connect the municipalities of Kamiyama and Mima while passing through varied woodland with different tree species.

Until the early Edo period the summit held a single hokora. A dispute between the people of Koyadaira and Kamiyama villages over its affiliation turned violent, after which two shrines were built facing opposite villages: Tōgū Shrine for Kamiyama and Shungū Shrine for Koyadaira, with separate worship halls. The name appears in the Edo-period Awa-shi as Tōgū-jō, linked to a tradition that Emperor Tsuchimikado stayed here.

Locals call the mountain "Otōgō-san". Two shrines stand on the summit, each facing a different village: Tōgū Shrine, dedicated to Amaterasu Ōmikami and Kunitokotachi no Mikoto, and Shungū Shrine, dedicated to Emperors Tsuchimikado and Gosaga. Until recently, the spring festival on the first day of the fifth lunar month brought the two villages together, sometimes clashing their portable shrines.

The mountain can be reached from starting points in Kamiyama or Mima where established trailheads are located. Spring and autumn offer the most favorable conditions for hiking, with mild temperatures and good visibility along the routes.

The summit's official triangulation point is named "Harumiya-yama", not Tōgū-san, and its 2024 survey gives 1090.52 m. Locals also call the mountain "Otōgō-san". The summit itself is wooded, so there is little view.
