My Take
JIRO — born Yoshihito Wayama in Hakodate, Hokkaido, in 1972 — plays bass in Glay, and if you only know Japanese rock casually, that band is one of the load-bearing walls of the whole house. Bass is the position nobody points at. The singer gets the poster, the guitarist gets the solo, and the bassist gets the job of making the song physically move you without anyone noticing why. That is a strange kind of career to choose, and an even stranger one to sustain for the better part of four decades in the same group. What tells you the most about him, I think, is The Predators, the side band where he also plays bass. When your main act is already one of the biggest in the country, a side project is not a career move — it is just someone who wants to keep playing. That instinct is usually what separates a musician from a rock star, and he reads to me as the former.
