Probably the unpopular opinion here, but I foresee things going back to "normal" a lot more quickly than some are thinking. Will things change that much? I don't think so.
This is one industry that has weathered every storm that the earth and her environment could throw at it and just like clockwork, the industry marches on.
Some providers will stick to online content - but I can't ever see this as a substitute for real, physical meetings.
Other providers will go right back to normal as if nothing happened.
A small percentage will quit altogether, never to return.
More providers will enter the industry due to the economy downturn as a fallout from the shutdowns we've experienced globally.
The local Japanese market will fire right back up (some of it already has) and the foreigner/visitor market won't return until Japan allows entry once again.
I can't image the U.S. visitors being let in anytime soon though, it's still quite the circus over there.
The client side of things, I'm sure there will be some mirrored actions - Some clients will bow out completely, some will stay online only and others will just go right back at it. Can't say that the client base will increase... it may decrease if the clients lose access to their cash that they'd normally have pre-corona.
Who knows. It all depends on what happens locally and what the public attitude is when it comes to getting things back to way things used to be. Certainly, the general public is frustrated and tired... people are already getting out as the weather warms up.
Do what you feel is right for you, that's all I can say.
