Just how rhetorical is your question, Kristoffer? Are you planning to travel to Japan yourself, or someone else? Which budo style(s) will be studied? Our answers are likely to depend on yours.
My wife & I have family in Japan, & also are able to coordinate through senseis on both sides of the Pacific who come & train in our Hawaii dojo. And MJER dojos are a lot more prevalent in Japan than other, less-practiced ryuha.
So I'm not sure that a general question like yours can really be addressed without more detailed info.
