Dotonburi of Osaka is super crowded, where takoyaki, tall buildings with giant posters, giant signboards, giant mascots rule the landscape. The place definitely has a very different vibe from that of Tokyo, Kyoto and Kobe. The feel is very Japanese, in a loud, direct, hearty, lively way. As compared to other places in Japan that I have been to, saved for Oishi Park and Arakura Sengen Shrine, there are a lot more tour groups here.
