I was recently told that there are regular Tsugaru-Jamisen (a 3-stringed banjo-like instrument) and Te Odori ("dancing" with hands & arms from a seated position) performances held at the 津軽三味線観光会館 (Tsugaru-Jamisen Kankou Kaikan aka Tsugaru-Shamisen Tourist Hall) in 焼山 (Yakeyama).
The Hall is open Mon.-Sun., but dance performances are only on Sundays (I think). It's closed on the 2nd and 4th Tue. of every month. The 3rd Wed. of every month is "Social Welfare Day" (福祉の日) so dance performances can also be arranged with advance reservation for that day(?). (Not 100% sure about that part...)
Admission is 600yen for adults, 500yen for high school students, and 400yen for junior high and elementary students.
