Thank you for sharing the clip, Sifu Eric san.
Yes, I have heard of them. 鴻龍會 (kouryukai) is one of the rare Chinese martial art clubs in Japan.
Almost most of the Chinese martial artists in Japan are practising Northern styles. May be because those people normally go to Taiwan or Beijin to learn styles.
There are some Southern style Chinese masters in Japan, but somehow the Japanese tends to prefer Northern styles because many people still believes (or are brainwashed) that Northern styles are specialised in internal cultivation which gives special power or super abilities.
Of course, this notion is incorrect. This is mainly due to their lack of knowledge in Chinese martial arts.
