I met a new instrument named Wako (和胡) the other day. It's similar to erhu (二胡). It's made from a Japanese instrument maker and played by a Wako player, Satochiki (里知帰).
I got help from the Bing Chat for explaining the instrument.

Correcting and revising with my translation
Satoko Kiji → Satochiki
Bing Chat helps me to know the information of Wako in Engish. The name of the player was incorrect, so I mainly changed it. My revision may not be perfect, but I hope this information helps to understand the new instrument Wako.
There are YouTube videos from Satochiki. His performance is amazing. I hope I have a chance to see his concert someday.
