Could this be a good thing? Sure there are going to be sheisters, but they may be needed.
I would say "no", that Japan certainly doesn't need a flood of lawyers.
While I appreciate that there is a small shortage, and indeed some rules have been changed to allow judges to act also as lawyers to cover that shortage, these wholesale changes I think are unwarranted and will have the same dismal effect that such a large parasite class has had in the U.S.
