Is this an issue with Navidrome or with the Spotify API?

I think it should be Navidrome , I have found the correct item in his response when I use Spotify API

I've looked into this, some Japanese artist can still their images obtained. However there is an internal checking whether the searched artist name is the same as artist name from metadata:

core/agents/spotify/spotify.go

	// If the first one has the same name, that's the one
	if strings.ToLower(artists[0].Name) != name {
		return nil, model.ErrNotFound
	}

For some artist, artist name obtained from Spotify API is romanized, for example: 平沢進 is listed as Susumu Hirasawa. Not sure if there is a localization setting in the API, as the response JSON you attach is properly listed in Japanese

There is a "market" parameter for the spotify search API, but I'm not sure it will help as in the documentation it says that the parameter only changes whether the item is available in certain countries or not. Also the country region of the the user will take precedence over this parameter.

For reference: https://developer.spotify.com/documentation/web-api/reference/search

I guess the fix would depend whether we want to just trust the first search result (as we did, but right now we double check whether it is the same as our file's metadata - which is the root cause of the bug) or maybe we could refer to other information to get the proper artist image

I would like to work on this issue after we decided which approach we should take

This issue has been automatically marked as stale because it has not had recent activity. The resources of the Navidrome team are limited, and so we are asking for your help.
If this is a bug and you can still reproduce this error on the master branch, please reply with all of the information you have about it in order to keep the issue open.
If this is a feature request, and you feel that it is still relevant and valuable, please tell us why.
This issue will automatically be closed in the near future if no further activity occurs. Thank you for all your contributions.

just commenting to avoid staleness. I am thinking about using the LANG tag in the music file to detect the market. Is that something feasible ? Furthermore, is there a way to load the artist images manually without going throught the directory structure, like <artist-name>.jpg or so ?

So other japanese devs have also faced this issue and have found that adding a Accept-Language: ja header in the curl request works.
I think this combined with @vnghia 's suggestion will work for other languages as well, given that the music file actually has that tag.
BTW I wanted to use MusicBee to download and manage the artist images as artist.jpg in the artist folder alongside the album folders, but apparently it only handles that for album covers...bummer.

EDIT:
On second thought, it might be easier if we just let the user choose which languages to search for, instead of relying on tags. I guess it's a bit spammy in a way from Spotify's POV since we'll send as many requests per artist instead of 1, but this operation is pretty negligible since it's only a one time thing.

Adding an artist.jpg should work too, if all files for that artist are in/below that Artist folder.

I think the correct behaviour is to use the language tag from the file. We don't want to spam Spotify's API to avoid bumping into rate limits or worse, having them blocking Navidrome for all users!

And it will be only one request per artist. Once we get a response from Spotify, the images are saved in the cache.

If anyone wants to work on this, they are more than welcome :)

@vnghia, currently the way artist images are resolved is described in the link posted by @metalheim above: https://www.navidrome.org/docs/usage/artwork/#artists

I've created a PR utilizing the "SortArtistName" which should be in Latin characters for any artist. I've noticed just now that navidrome has musicbrainz integration, so I guess that is also another way we could query/match the artist name, but the PR addresses most of the problems I had initially.
