If you load your Japanese music files into Mp3tag, do you see the TITLE, ARTIST with all the correct characters?

To save them in ID3v2.3 UTF-16 you can set the Mp3tag Write-Options for ID3v2 accordingly:

You can find the details in the [documentation](https://docs.mp3tag.de/customization/options/tags/mpeg/#write).

Please note that the encoding settings only apply to mp files.  
Flac files get tags encoded in UTF-8  
See here:

> Using Windows 10 and mp3tag for adding metadata to FLAC files. Since my keyboard does not directly support foreign characters, such as those found in Celtic music and other non-USA English music forms, I've been using Character Map to add them. However, it turns out that these characters are not necessarily UTF-8 compliant. This causes problems for us in ways too complicated to explain here. That said, how can (or should) Character Map be used to properly insert UTF-8 compliant characters that…

BTW: the tag encoding has nothing to do with the filenames.

thank you, I found the problem

flac can be correctly loaded

only wav file error, so I think problem is on spotify with wav instead of UTF-8 or UTF-16…
