Mt. Nebisodake (1,112 m) in the eastern end of Toyota City, Aichi Prefecture, is the highest mountain among the mountains in the Mikawa highland, which is surrounded by the mountains with an altitude of over 1,000 meters. Composed of granite in the Cretaceous Ryoke metamorphic belt, the mountain has a gentle appearance and it is easily accessible. The area is a part of Aichi-Kogen Quasi-National Park.

Blessed with bountiful nature, Mt. Nebisodake is always bustled with hikers and birdwatchers, who come with the aim of watching various wild birds including tits. Flowers of the family of Asteraceae such as asters and thistles and many other seasonal flowers come into bloom in the flower field at the top of the mountain.

The mountain top commands a panoramic view of the surrounding mountains in the Mikawa highland and the Kiso mountains in the direction of Asuke Town. On a fine day, Mt. Ontakesan can be seen in the distance.
