For Personal Use
For use as background music for non-commercial videos
You may use my songs as long as you clearly state the credit in the description or in the video. When uploading videos to YouTube, please note that the Content ID system may react to some songs, but your channel will not receive a copyright strike.
For creating a derivative work as a rhythm-game chart
The sound source must be clearly credited.
Secondary distribution of sound data is prohibited.
Please keep it strictly for personal use.
Some games with level editors may have their own guidelines, so please follow them.
I may not be able to respond to questions about this type of use.
FAQ: About Workshop-Style Redistribution of Custom Charts
A Dance of Fire and Ice: Creating and distributing custom levels is allowed. However, the use of “songs not covered by these guidelines” is prohibited.
osu!: Only audio tracks officially permitted as Featured Artists may be used.
Geometry Dash: Videos of custom levels may be uploaded to video platforms, but distributing the levels or audio is prohibited.
Dance Cube: The use and distribution of custom charts is not allowed.
Other titles: For special cases not covered by these guidelines, please contact me by email.
Reprinting, especially for listening purposes
This is generally prohibited. (It doesn’t matter if it’s not for profit.)
If you strongly wish to publish my music on your platform for any reason, please email me in advance to discuss your request.
For Recording and Inclusion in Rhythm Games
For use in non-commercial games
Please contact me by email if you wish to include my music in games that have already been released.
You may not incorporate my music into your own game or application without permission.
Please be sure to inform me in advance and include a description of your game.
For Commercial Use
This will require a paid contract, so please contact me by email.
*Except in cases where the development team has a history of releasing other games that have already been completed, when the game is still under development and has not yet been released, in principle, I will decline the use of works, regardless of whether it is for commercial or non-commercial purposes. (I may not be able to respond to your request.) Please contact me after your game has been released in a playable state.
For Other Use or Commercial Use
Please contact me by email.
Songs not covered by these guidelines
The above guidelines do NOT apply to those works.
Please follow the guidelines provided by the respective companies, if available. Please refrain from contacting the copyright holders regarding personal use, as it may cause inconvenience to others.
