While the yakuza used to pride themselves on not preying on the poor and weak, the tokuryu have no such scruples.
They make much of their millions from conning Japan’s ageing population
Tokyo police – who called them their “biggest public order priority” – set up a 100-officer taskforce in October to “destroy” the groups.



I have a feeling the Yakuza’s definition of poor and weak was pretty flexible.
Edit: It mentions at the end they’re getting in on the scams too now.
