doms got ya covered. my brother is a pastor/evangilist. he has been ministering in japan, new zealand, korea, for over 30yrs. he has been led to minister to young and old, but mostly bikers and yakuzas and mma fighters in japan, and also maori bikers in new zealand. one of the yakuza (mr.suzuki) was in the subway when he heard my bro sharing the gospel message. he was not happy with what he had to hear at the time, and went on his way. few days later, mr. suzuki came back looking for my bro, and said to him that "what youve said had changed my veiw of things in life". making a long long story short, many of the yakuzas (high ranking in their district) have left the life of yakuza. yes, strange but true. ex-yakuza, ex-hells angels who gave their lives to the Lord. theres a short docu on youtube regards to mr. suzuki. my bro has a M.C. called the "Lords Angeles" spread about japan. not all are christians, yet the purpose is to enjoy the brotherhood, and having the same interest in motorcycles. theres a documentary on a video that i have, but not sure if thats on youtube?
