Welcome to Saidera Mastering TOKYO style 

Saidera Mastering was established in 1996 by Seigen Ono (Founder, CEO). Our main studio (basement level, with a floor-to-ceiling height of 4.4 meters) was constructed in 2000 in Harajuku, Omote-Sando; the very heart of Tokyo known for its premier fashion stores and restaurants.
We provide world-class mastering services, capturing our client’s specifications and desires, to deliver the best sound possible across all listening platforms.LinkIcon
Please feel free to contact me or our booking manager: Tatsuji Kimura, via this CONTACT form with any questions or queries (if possible, please use simple English like NYC taxi drivers). And we will endeavor to assist in finalizing your music in preparation for release.
Additionally, through our extensive experience in the industry, we can provide the opportunity for an introduction of your work to Japanese distributors, press, and promoters.
Since 1987 we have run Saidera Records. More recently, in 2015, we established the SDM&LiveRec record label, a secondary facet of Saidera Records. We specialize in high-resolution digital audio for digital distribution, available for both stereo and multi-channel music. We are always searching to release new talent.
