Underground Garbage Collection System
Did you know that Tsukuba has an underground garbage collection system? It is only available to certain houses in the central part of Tsukuba. I think it was installed in Tsukuba because it was the “latest thing” when the city was being developed and they wanted the city to be at the leading edge of municipal services such as garbage collection. Unfortunately, it seems that the idea never really caught on, so there is talk of scrapping (no pun intended) the system.
