Are Japanese aquariums really that bad or is it a perspective issue?

Hi! Let me know if this isn’t the right place to ask this. So I’ve been planning a long trip to see every major aquarium in Japan. So think of the biggest ones in each city/prefecture. I grew up with an aquarium that has accreditation with AZA (Association of Zoos and Aquarium) so I assumed all aquariums follow that same criteria. But, recently I’ve been seeing a lot of people talking about the sad conditions of the zoos and the conditions the animals seem to be in. I do want to go see cool aquariums but I don’t know if it’s a good idea. I’m not sure if the aquariums are bordering on harmful or it’s just a perspective issue. I’m not a marine biologist so any perspective or anything that can shed more light on this would be great!
