Not understanding the lyrics can be part of the appeal, because it makes them less distracting.

Understanding a little can make embarrassingly cheesy and saccharine pop lyrics take on a profound poetic quality.

Growing up on anime and Japanese video games is probably a big contributor to finding the melodies appealing.

Also, dude's got a giant concert video in view pretty much constantly, so image is probably part of it.

hope this helps

Ok thanks, the japanese video games + anime answer puts it into perspective, I hadn't thought of that. I could see how growing up with either of those would mean listening to that music then would bring good memories or feelings back.

It's not nostalgia, I didn't grow up with Japanese culture. And it's not that I can't understand it - I can. I just like the music. Japan has the second largest music industry in the world after the US. They produce a huge, diverse group of interesting music which stands fine on its own merits.
