Morelock

Specifically will be staying in the Setagaya Ward, but of course trying to see as much as possible in the couple of weeks we'll be there. (~Late March-April) It's tough to find any information online, anyone have any experience possibly renting a bike and riding a track. I figure most of them are strictly business/racing, but just not sure. I plan to visit a few and watch some races, but I'd feel bad if I didn't get to ride one while I'm there, or is that just not a thing that is done.
