Japanese time, English conversation

A Japanese round was announced, but one pair kept talking in English: one partner didn’t speak Japanese. Staff let the conversation continue. This was a two-hour café exchange in Shibuya. One first-timer paid about ¥1,050: ¥600 in advance plus roughly ¥450 for oolong tea. By the time they sat down, check-in, table assignment and the drinks queue had used about half an hour. The exchange portion itself lasted about 75 minutes. The first table had four people. Staff called for 15 minutes of Japanese in that first round, then moved two people at a time between tables. By the final round, there were about five minutes in English and five in Japanese.
