The yakuza is still alive and well.[1] They keep a lower profile now than during Japan's boom times, much like the mafia in the US today. I dunno about MS-13 per se, but I've definitely run into an outsized share of sketchy central and south American immigrants in nightclubs in Osaka. A Canadian DJ friend of mine (long-time Osaka resident, like 10+ years) cautioned me to avoid them. They had a reputation for violence, stabbings, etc...
