Japanese Yakuza

From two days ago, people living in Tokyo have been seething with fear.
There have been battles of Yakuza in the middle of Tokyo.

On the 8th of Febuary, one man from Sumiyoshi gumi was killed by two guys from Yamaguchi gumi, and then this battle has been getting worse.
On the 9th of Febuary, two man from Yamaguchi gumi did the counter attack by firing guns at Yamaguchi office in Shibuya and Toshimaku.

Apparenlty, it is because of territory conflict in Ronppongi and Shibuya.

In Japanese, Yakuza stays each city and gets money from people who opens shops in their territory for no reasons, and this is called Mikajime ryou.
In the eyes of the law, you DON't need to pay for it, but the majory of people pay the money for their protection from other Yakuza.

This is one of the resrouce of Tokyo's Yakuza.

Yamakuchi gumi is the biggest Japanese yakuza group from Kobe, and Sumiyoshi gumi is the biggest yakuza group in Tokyo.
