Wakakusa (若草町 Wakakusa-chō?) is an area located within the city of Minami-Alps in Yamanashi Prefecture, Japan. It was formerly a town within Nakakoma District.
As of 2003 it has a population of 11,671. The Japanese kanji can be translated as "Young" - "Grass".
Wakakusa is located approximately 12 kilometers from Kofu. It covers an area of 10.29 square kilometers and lies on latitude 35° north and longitude 138° east. Wakakusa is a relatively flat area with many rice fields and orchards. The Kamanashi River (釜無川)forms its Eastern boundary.
Long ago there were many independent hamlets between the Kamanashi River and the Japan Alps. At the beginning of the Meiji Restoration three hamlets—Tōkaichiba (十日市場), Kagami (加賀美), and Terabe (寺部) merged to form a new village called Mitsue (三枝).
After World War II, Mistue merged with Tōda (籐田), Asabara, and Kagaminakajō (鏡中條) to form the village of Wakakusa.
Wakakusa was independent until 2003 when the city leaders decided to merge with the towns of Kōsai, Kushigata and Shirane, and the villages of Ashiyasu and Hatta (all from Nakakoma District) to create the city of Minami-Alps.
