Jiro

He married in the year 2000 to a woman named Reiko, a former editor of the music magazine What's In.

Jiro grew up the only son out of four children, his father a carpenter. Jiro used to be a guitarist in his first bands, and only picked up the bass when he joined the indie band "Pierrot" in Hakodate (different from the well-known band of the same name). Jiro first became familiar with Takuro and the rest of GLAY as they attended another high school in the same town, and were mutually involved in the local indie scene. In 1992, Pierrot moved to Tokyo to expand their career, but disbanded shortly after. He states that during this time he owned nothing other than what he had carried in his backpack when traveling from Hakodate, and had walked part of the journey to save money. Jiro worked in construction in Tokyo before being invited by Takuro to join Glay. At first he declined due to his doubts about a stable career in music but as Takuro insisted, he agreed to play one concert with them. He ended up staying in the band afterward. When asked his name after one of his early gigs with the band, he was reluctant to reveal his given name which he felt was "uncool" and spontaneously chose the pseudonym "Jiro" which he continued to use as a stage name and nickname from that point onward.
