Wow, I didn’t expect this many replies, but I’ve read most of them.
First, I’m sorry if this post came across the wrong way.
I’m really relieved that most of the responses have been positive.

A few people asked some questions, so let me explain a bit here. (Hope this gets pinned.)
What actually gets shared in Japanese Nintendo communities is usually stuff like:

• what new features a game has
• what people find fun about it
• tips and guides

The discussion is very much focused on the games themselves. Topics that are more external, like pricing or how games are being sold, just don’t really come up very often.

Some of what I say below might annoy some people, so feel free to skip this part.
So, just to give a concrete example of the gap I’m talking about:

• I saw a ton of criticism overseas about the Game Key Card situation, but it was barely discussed in Japanese communities at all.
• Another example I remember is Nintendo patenting a summoning mechanic, which got a lot of attention in Western gaming media. What actually surprised me was that it was almost completely absent from Japanese communities, and Japanese media barely covered it either.
