From the Times:
“Not once have we had any trouble with any of our neighbors,” Mr. Fukui said. “That’s because our second chairman was very strict in that respect.”--Czobit
So as not to inconvenience their neighbors, the Dojinkai eschewed the telltale flashier trappings of their counterparts in bigger cities.
They were forbidden to wear double-breasted suits. They were told to be circumspect while getting in and out of their cars by not lingering outside, and not to park their cars ostentatiously on the streets.
“We’ve seen how the yakuza in Osaka or Tokyo occupy the streets with their cars, but we were explicitly taught not to do that,” Mr. Fukui said, adding that Dojinkai members are also taught to exchange greetings with the neighbors. “We are stricter on this point than most ordinary companies.”
