In 2009, he became the Audio Meister of Asahi Kasei Microdevices. Since then, he has brought into the world the VELVET SOUND series of DAC chips, including the AK4490, AK4497, and AK4499. They are used in numerous pieces of audio equipment.

His hobby is making speakers and he uses an exclusive Fostex unit to listen through his own enclosures.
