Fun facts: He learned fashion design. His nose is the ticklest part of him. He wears contactlenses. On his free days he forgets his laziness.
Toshiya has a red bedroom. He wanted it so, because red generates energy and excitement and he needs these when he finally gets home after a hard day's work.
Embryo was the very first song when he played on his bass using his fingers instead of a pick. Even now he alternates between the pick and his fingers.
Toshiya's apartment got soaked once: on the first floor he noticed the wet carpet, but no matter how he tried to dry it up, it got wet again. He called his landlord but it was late: all the wooden furniture in his house got wet and moldy!

Toshiya is the only member who was not a part of La:Sadies before Dir en grey; he came from Deathmask. When he first met with Dir en grey, he couldn't decide what to think of them. He had heard some rumours about them, particularly about the blonde singer, Kyo. But he was impressed when he heard Kaoru scold a man who had claimed that they wouldn't make it as a real band. Kaoru told him in a proud tone that they surely would be famous. And it turned out that Kaoru was right after all. Toshiya often states jokingly that he was "kidnapped" by Dir en grey, but he seems pretty happy to be their "victim".

Before he picked up the bass as his instrument, he had tried many before, like drums and guitar. However, he chose the bass because it had less strings and he thought it would be easier to play on it, but soon he had to find out that wasn't true. He spent lot of time practicing and thus he became one of the most talented bassist as a result. You just have to check out his bass solo in Cage, it's absolutely wonderful: his play is continous and the melody flows perfectly. Or you just have to listen to "Itoshisa wa fuhai ni tsuki" (which is on their new album); this song seems to have been made to show off Toshiya's bass.

Toshiya - as Kaoru - is very good at drawing, he often makes comics of his band mates, also he is a big fan of anime and manga. Actually, a lot of his influences in his costumes came from reading them. He loves watching horror movies.

He didn't have many boys in his neighbourhood to hang out with, so he just played with the girls instead. This had its drawback with his class mates later, for they became very jealous of him.
