@MrZuerrer
Brilliant work! It's weird that we "have to" reverse-engineer it, as @bespired said, but it's pretty amazing how you were able to come up with those numbers. I'm curious, are they based off of any type of logic, or just magic numbers to "make it work", so to speak?

My use case involved solving a puzzle with the solution pointing to a particular public phone in Osaka. Hence my need for precision.

The parameters I used are "well" documented. You can find one such example in https://gis-lab.info/docs/nima-tr8350.2-wgs84fin.pdf. Documentation, however, is not meant for the uninitiated such as me... But I am persistent ;-)

BTW... I used Mapion in the past but did not realize they also provide MapCode. I will refine my PowerShell / Selenium script to drive the Mapion web page (e.g. https://www.mapion.co.jp/m2/34.735775957141,135.55287836095266,16) and with a few simulated clicks I can get the MapCode.
This addresses my requirements in a pragmatic way and given I typically need less than 50 waypoints, I can easily feed the coordinates to the script and collect the MapCodes.
