Speaking part at the end:

俺の出番は以上だ。
あぁ。懸命に歌ったら暑くなってきたぞ。
一枚脱ぐか。
ん？なんだ日本、暑くないのか。 (why do I picture a D: face Japan here LOL)

So I guess Germany's Hata Futte Parade sets up for Japan's next, and I'm guessing at the end of Japan's it will allude to England's. Actually the end of Italy's also alludes to Germany's so this is probably true :D
