Ask Japanese bassists — not fans, bassists — to name the country’s greatest rock four-stringer, and one name keeps surfacing: Taiji Sawada. The evidence sits inside three albums that happen to be the foundation of everything X JAPAN became.

More Than Fast

Vanishing Vision, Blue Blood, Jealousy — the golden run. What TAIJI put into those records goes far beyond keeping up with Yoshiki’s drumming, itself no small feat. He brought slap and pop technique into speed metal when the genre worldwide treated bass as a shadow instrument; he played with a funk player’s rhythmic wit inside songs moving at thrash velocity. Listen to the bass on Blue Blood’s title track or the runs threaded through Silent Jealousy — that’s not accompaniment, that’s a counter-melody with an attitude problem.

And then there was the other TAIJI: the arranger. The acoustic textures in the band’s ballad architecture — most famously Voiceless Screaming, which he wrote — revealed a musician whose instincts ran orchestral, a man equally fluent in flamenco-tinged acoustic guitar and metal thunder. X JAPAN’s signature move, the swing between overwhelming force and devastating tenderness, wasn’t only Yoshiki’s design. TAIJI built half of that bridge.

The Exit and the Road After

He left the band in 1992, at the height, under circumstances neither side ever fully aired — one of Japanese rock’s sore spots. The chair went to HEATH; TAIJI went on to LOUDNESS, joining the country’s other world-class institution, and later led his own band D.T.R. The years that followed brought real hardship, which he wrote about with unusual honesty — the memoir is one of the franker documents Japanese rock has produced about what happens after the arena lights.

Then, one grace note: in the summer of 2010, TAIJI appeared on stage with X JAPAN again at Nissan Stadium, bass in hand, the original foundation standing with the band one more time. He died the following year, in 2011. The reconciliation had come just in time to be real.

The Verdict

Dynasties get remembered by their emperors, not their architects. But play those first three albums and the truth is right there in the low end: before X JAPAN could conquer anything, someone had to pour the concrete. His name was Taiji Sawada, and Japanese rock has never replaced him.
