Maybe a Sim City scenario?
There’s also Capitalism (1995) or its sequels that you might be able to find. I’ve never played it, but they reused the engine for Seven Kingdoms which was (and still is!) an excellent RTS.

It’s not exactly “set in the Japanese finance ministry”, but it’s contemporaneous with your time period, and the developer is from Hong Kong, so maybe it’ll scratch your itch.
Which phone?
Have you been mucking around in the developer options?Have you tried backing up and doing a factory reset?
I had a similar issue, and it seems to have been resolved by setting things in the developer options back to default, then turning off developer options entirely. No idea why that matters, but it was the recommendation in the Grapheneos forum.
It’s open source, you’re welcome to do it. STK is GPL while Godot is MIT, so I don’t know if that would be easy.
But I doubt the STK project would be receptive to that. You’d be doing it on your own, and STK has a pretty small audience as it is.
Perhaps you should see if the STK project wants developers to improve the graphics quality (while still remaining performant on old devices).
Have you worked with https://wiki.archiveteam.org/index.php/Main_Page?
I am also subscribed to [email protected] so I made the same mistake
