Kozan is amazing at playing the shamisen. He is a great teacher, very friendly, and very good at giving direction. I had no trouble playing the shamisen, and picked it up quite easily. Also, ask Kozan to demonstrate playing the Koto on your visit... you won’t regret it. If you’re after a traditional Japanese experience, I suggest trying this out as it fun and unique activity... one to boast to your jealous friends about back home!
As an added bonus, he made traditional Japanese tea for me which really hit the spot.
