The former Taiwanese president Lee Deng-hui is doing his part, urging Japan to regain her "Samurai spirit", on his previous visit to Japan not long ago, if I remember correctly.
Japanese ultra-rightwing will come out of the shadow in not so distant future, as a legitimate political force. Yes, they will stay as allies of America this time around. But not necessarily the allies of other American allies in Asia. Kishi Nobuske would be smiling in his grave. He was the architect of the postwar Japanese political order where submerged pre-WWII elements called the shots most of the time. His plan has worked so far. Most of prime ministers have come from a kindergarten he set up to groom his successors. All it takes is another serious international crisis. It could be coupled with a domestic economic crisis as well. There is a view in Japan and in a part of Asia that the worst is over with Japanese economy. However, it is still not clear whether all bad debts are finally taken care of. That may be an wishful thinking.
