Welcome to the forum John, and greetings from the heart of Japan, Nagano. those little stands are usually around during festivals, are kind of a closed group, in some ways, and may be hard to get net info on. It may be of good help to give us more info on just what it is you are looking to find out, and then some may be able to check later, and let you know. I have sold roasted corn on the cob, brushed with sweetened soysauce in the past for a neighborhood booth at a festival in Matsumoto. It was a
Shinto shrine festival, we ordered the corn from a co-op connection, provided our own grill and stuff, used the tent and set up which the shrine rents from a purveyor of sorts, and did it. That's it. The excess money above costs, went to the shrine, of course, but that also kind of helps the neighborhood--or at least so we are told. (That was some 19 years ago)
I hope you have fun on the forum, and check out the whole thing !! See you 'round !!
