No, I didn't. We are talking about if a visa is required to do a transit in Japan. The answer is NO. When you arrive at a Jap port of entry, your passport is to be stamped with a "permit" of staying for X days.
With Chinese passports, we are allowed to stay for 72 hours for transit without pre-issued visas. This is a protocal between the two countries for years.
If you are a Chinese passport holder, you will be allowed on the street if you get a shore pass (寄港地上陆许可- a stamp on your passport), it is not pre-issued, but you still need to apply for one at the airport.
