Very nice experience. Hiroki sensei knows his stuff and moves with great precision and speed. I've certainly learnt some new things and got the chance to ask, discuss and learn about technique as well as train (train with body and mind). The training covered the main aspects of karate: kihon, kata and kumite and was great for trainees of any level. Highly recommended.
Oh, did I mention the teishoku meal at the end was amazing? Very, very good sashimi and grilled fish. Great way to finish training.
