About us

As Catalyst​

A recording engineer's job is not just to record sound. We want to be a catalyst that brings out the artist's charm and potential to the fullest while working closely with them.

Of course it's important to hone your skills, but what can STUDIO 407 do for you? I think about that all the time.


​To leave an impression

A vivid "rhythm" that excites your heart. “Harmony” is etched into a distant memory. A sweet and sad melody. Music has the power to move people's hearts and bring joy to their lives. The world seems to look different before and after listening to it... There is no doubt that a person's ``heart'' will become richer by accumulating such experiences one by one. “Surprise and excitement” are the source of richness. Music colors scenes in our lives with ``surprise and excitement.''

Through my work as a recording engineer, I hope to deliver the music created by musicians in a fresh package to as many music lovers as possible.

I look forward to the day when I can work with you all.

At Sony Corporation, he participated in a piano research team as a sound creator. Engaged in research on the relationship between the piano's structure and its resonance, and the relationship between the pianist's touch and the tuning performed by the tuner. Our goal is to master the sound of the piano as a recording art that combines technology and art, and we are currently actively working on it.


As a recording engineer, I pursue the highest sound quality and am passionate about meticulous work. Music is my joy in life, and I always do my best to bring its beauty to as many people as possible.

My philosophy is to combine technical knowledge with artistic sensibility to capture the true soul of music. Attention to detail and the pursuit of the ideal are key to my work. We strive to ensure that each note, each timbre, has perfect balance and resonance.

Being immersed in the rich world of music is a moment of bliss for me. The moments we create together with artists are full of joy and emotion. I am always in the pursuit of innovation and am committed to using the latest equipment and methods to produce the best possible results in classical music recordings.
