>>89239092>How much interaction do JP idols have with fans and in what form?My experience might be outdated (already quit following idol for more than a decade), but that varies. Generally, the more popular an idol / group is, the harder to interact with them.
If we are talking about AKB, they perform almost daily in their mini "theater" for fans. That's more of a medium-sized hall with roughly 200 seats than a traditional theater, so fans are only one or two steps away from the members. There might be a semi handshake / hi5 session at the end of the day with the girls lining up on the way out to say goodbye. This is mostly done by less popular members; While top members do come now and then, the more popular they are, the less time they have for the theater (some of top members' birthday celebrations were delayed by a good 2-3 months).
Then there are two types of handshake events. In National-type handshake event, one ticket earns you 10s and you can use up to a maximum of 3 tickets at a time (30s in theory, closer to 25s practically before ojii-san guards hug and forcefully drag you away). It's way harder to apply for and win tickets for the more popular members than the less popular ones (the lines are long, too, popular members can sell out several 2-hours-slots while less popular ones might empty their lines within minutes - they still have to stand there for the entire timeslot even if their line is empty so you might be able to requeue for them if you still have tickets left).
There are blogs as well, but they are similar to Twitter so don't expect too much interaction from those.
Those are the most common forms of interactions I can recall. All in all, I'd say it's a lot easier for VTubers to interact with their fans and vice-versa outside of some edge cases
