The Yamasa Institute (Japanese: YAMASA言語文化学院) is a private Japanese Language school located in Okazaki, Aichi Prefecture. The Institute began language instruction in 1989, and was founded through the Hattori Foundation, a philanthropic educational organisation established in 1919. The Yamasa Institute is the only accredited Japanese language school in the region, and has built up a reputation for providing high-quality tuition in an international environment. The school originally occupied one floor of the “Yamasa II” office block, but has grown to incorporate the whole of the building.
