Japan does have a drug problem, just not in the sense you are thinking of. Yakuza is not going away, just its power and influence in many areas.
Yep, they will adapt to tougher laws and go more underground, but yakuza will always be involved in Japan, there will always be outcasts in the performance-oriented Japanese society who can only make a name for themselves in the underworld.
Difference with LCN they still have links to top politicians and business leaders.
