They are? Honestly, first time hearing about this. I've noticed only big events get posted outside of the IG/etc. Even in Tokyo, a simple thing like checking if a place is open on a public holiday is to check their Instagram.

Sadly in Tokyo, most businesses post their info to twitter or instagram, but in both cases you're able to read without an account (not well, but it's possible).
