Vocal Trainer
Vocalist / Singer-Songwriter
From 2017, gained experience as a vocal trainer at a major vocal school.
Has taught over 1,000 students, working in a wide range of settings including group lessons at idol and TikTok agencies.
Moved to Tokyo after becoming an audition finalist. Has performed at many live houses in Tokyo, including morph-tokyo in Roppongi, as an acoustic solo artist and band vocalist.
Began serious DTM music production in 2020, expanding into composition, arrangement and music production.
Currently focuses on flex-time vocal lessons, giving guidance tailored to each person's voice and goals.
Every singer has a different charm.
Voices are individual, and so are strengths and weaknesses. That is why, instead of applying one fixed method, I value finding the approach that suits each person's voice and challenges.
I myself have long engaged with music, not only through singing but through live performances and songwriting. Drawing on that experience, I want to deliver lessons that go beyond technical improvement, helping you know your own voice and enjoy singing more.
What do you need right now? Let us think it through together, one step at a time.
I would be glad to help you find the singing that is truly yours.
Everything happens in LINE. Move forward only when you need to, between your activities.

Just send your recording via LINE.

You get your strengths and points to improve, in text and a demonstration video.

Record again with those points in mind and send it once more.
Watch videos to see how feedback works.
One chorus or the full song, it is up to you. A demo in progress, a cover before posting, or a song for a stream. Questions are welcome too.
Advice from your trainer usually arrives within 24 hours.
Practice with the advice and resubmit. Repeat as many times as you need.
From recording an original song to posting a cover or going live, we organize your progress and support you all the way.
Record. Send. Improve.
Record it, send it, sharpen it.
A new singing habit that fits between your activities.
For singer-songwriters and original artists
For VTubers and cover creators
For streamers who sing live
Just record and send between production, streams and posts. You get thorough advice by video and text.
This lesson is for active creators who want to level up their singing in limited time. For the right person, I believe it leads to results faster than anywhere else. If it is not a fit, you can switch to in-person or online lessons, so feel free to try it.
Ask via LINE anytime, whether it is pitch, how to sing the chorus, or anything else.
Quick replies by video and text, so you can use them in your next practice.
Resend until you are satisfied, and grow faster.
