is a Japanese tradition to compete for who can came up with the longest song titles!
last year there was BiSH's "Don'nani Kimi Ga Kawatte Mo Boku Ga Don'na Fuu Ni Kawatte Mo Ashita Ga Kuru Kimi Ni Au Tame"!
in the topic of the songs with the long names, a while ago i was talking with someone about hilariously long Jpop titles, the two longest i could find where one from AKB48 and i believe the other was a B-side from Momoiro Clover Z
unfortunately the titles are so loooooooong that i forgot how they are called, but yeah they were super long, they wouldn't even fit within the thread limit
