Hamtaro: Hamtaro's Birthday! - 3000 Hammy Steps in Search of Mommy

I watched the dub, which I probably would not have done if I knew going in that this was a musical. I don't even know why they adapted it, if that was the case. The singing was very inauthentic and phoned in, and the songs were basic af. And so was the story, although I wasn't expecting too much from it anyway. It was just something to throw on. But there's something terribly important we have to discuss. Hamtaro's birthday is August 6. AKA the day the United States dropped an atomic bomb on Hiroshima. Which is, obviously, an event everyone in Japan would know about,including the children this was intended for. WHAT IS THE SIGNIFICANCE OF THIS?? WHO DID THIS??? "It was probably just a slip or something. They just wanted him to be a Leo." OK, then EXPLAIN why Maxwell's birthday is November 5? AKA Guy Fawkes Day. AKA another terrorist attack with a bomb. IT JUST RAISES TOO MANY QUESTIONS.
