Just a log of “my transition” and what have works well.
I used Google Maps a lot. I have moved to https://mapy.com/ works surprisingly well for navigation and regular map need, not very strong in POI, but that was expected.
Google Analytics swapped for https://dashboard.simpleanalytics.com/ - should have done this way earlier, just an overall better product for my needs.
Exited Goodreads for https://app.thestorygraph.com/ - zero problems
ChatGPT/Gemini moved to https://chat.mistral.ai/ - this one is a slight downgrade on both functionality and results. (so I am still cheating a bit on this one)
Moved to here, PieFed from Reddit - not regrets.
I was using Brave and Duckduckgo/EcoSia from before. I would consider moving away from Brave for a similar private but European browser.
Try with openstreetmap. Maybe it works better for Japan.
OSM is good for some things, but is missing a lot in Japan last time I checked. It also has no transit, sadly. It also has no English (edit: for map labels, I mean) which is a problem if one’s Japanese isn’t native level (and even my wife who is native doesn’t know how to read place names in some areas, particularly in Hokkaido).
That does remind me that I should see if there’s anything I can add again, though.
