We'd discussed Japanese-style pork buns called butaman (which are much different from cha shiu bow) when talking about the newish restaurant called Hana in San Jose in the Mitsuwa shopping complex that serves them (and seems to be the only place in the Bay Area that does). Sorry, I cannot locate the original thread. My husband and I got back from Japan last week and I finally got to try the *real* butaman in Osaka and in Kobe's Chinatown and I have to say that Hana's is different to me. The wrapper in Japan is chewier and thicker and I prefer this kind. Still, the one at Hana is tasty.
My husband put together a webpage (linked below) about butaman with a few pictures of Kobe's Chinatown (which was really jumping on a drizzly Sunday afternoon) and full of street food, including butaman. One picture shows the line in front of the famous butaman shop Melanie had posted. Another place where we ate butaman is Horai in Osaka, which has a number of branches.
