Heyo! My wife and I will probably be in Japan in October and I read on the Kodokan's website that it's open to visitors and tourists for self-guided tours and to watch randori from the specator's seating area. I also read that there's a museum or a gift shop. Have any of you guys been? Was it worth it? I'm a Judo noob (yellow belt) so I know that I'd enjoy it but, since our time in Japan will be limited and my wife doesn't do martial arts, I'm just wondering if it's worth scheduling into our itinerary and how it stacks up as a cultural or historical site for a tourist who's generally interested in Japanese culture but isn't specifically into Judo. Thanks!
