It's probably been asked countless times, but

Lately I've been having a look at Deep Disney and I've noticed wait times are considerably low, and crowd numbers seem just as low. (Compared to Dec/Jan crowds which is what I'm used too)

Me and my mates are planning a trip to Japan next year, and with these current low crowd numbers is it normally like this during April or is weather playing a big part here?

Any help here would be great,
