Maybe he is the best, at least about Ushiro-Mawashi-Geri (high back-spin kick), in the Kyokushin history. By the way, he is so good at low kick, too. He got a waza-ari against Hovhannisian by a low kick before Ippon by Ushiro-Mawashi. He intentionally uses a lot of body blows and low kicks in order to lower his opponent's guard and wait for the best timing for Ushiro-Mawashi. So clever. Osu.
