Weak yen not always good for Tokyo stocks, some analysts say

A weak yen might not be as good for stocks as is often believed, according to some analysts, and investors should take care not to assume that currency woes are automatically good for the Nikkei 225 stock average. Concerns about “bad” rate increases have grown recently as 10-year Japanese government bond yields have climbed. The bond hit 3% for the first time in 30 years earlier this month.
