Trying to use indentation to illustrate dependencies, what is required for what, as of MArch 2016. Might depend on the country I come from, Germany, and change over time. Germans can stay for 3 months in Japan without Visa application in advance. This visa is glued into the passport, along with a paper “certificate of eligibility”. Startpoint for the dependency tree here is this work visa for Japan.
Comparing my commuting time and other relevant factors, considering a flat in different parts of Tokyo.
