Tsugaru-Shamisen is a genre of shamisen music originating in Aomori prefecture in the northernmost area of the Japanese island of Honshū. It is today performed throughout Japan, though associations with the Tsugaru area of Aomori remain strong.
The genre is played on a large shamisen with thicker strings than those used for most other styles. Tsugaru-Shamisen is easy to recognize by its percussive quality (the plectrum striking the body of the instrument on each stroke) and the lilt of the rhythms performed. -- wikipedia
