This is HK-japanese co-production, but mostly japanese, so I think we should change "country" to Japan
Here are the credits of Hong Kong version:

Title credit is from new version. The rest of credits are original:

Some actors should be added to the cast listing:
Leading actor - Shogo Shiotani (or Shiotani Shogo?)

I understand that he was quite popular japanese actor. He commited suicide in 2002
Matsuda Masaru

Lee Fat-Yuen

Wan Seung-Lam

Deleted old bad quality screenshots and a poster, and added portrait gallery and a new poster (need to be posterized)
There are also a lot of japanese stuntmen and extras, which hardly can seen, so I decided not to upload them to the DB
And here maybe that will help a little in identifying japanese cast and crew (this data is on japanese I think):
Title: HAKEN 覇権
Alias: HAKEN 覇拳
Alias: 覇拳 ふりむけば修羅
Script - 山本勝
Photographing - 鈴木郁夫
Supervision (maybe producer?) – Sonny Chiba
Starring: 塩谷庄吾 (Shogo Shiotani), 松田勝 (Matsuda Masaru), 黄秋生, 金剛寺美樹, 北尾浩司
