When I was first told about this, I had heard that we would watch a movie and then chat for about half an hour afterward. That sounded reasonable. I arrived to discover that, apparently, the movie idea had been scrapped, and we would chat for practically the entire time. Oh joy.
The topic was "holidays." People were given a handout with the national holidays of the home countries of all the people attending (or at least who had planned to attend, though some didn't make it). There were five of us from the US, one woman from Australia, one from Taiwan, and the rest of the foreigners were from China. The room was packed, with around 35 people who managed to show up. We tried to have a discussion...but it was hard to share in such a large group with three different languages flying around.
I did the best I could to translate between English and Japanese. My speaking skills, however, are not the greatest. Goodness knows what it sounded like to the native Japanese speakers in the room. It was much easier when someone would volunteer to say something in Japanese and I could translate that into English.
After about an hour of that painful mess, we stopped for snacks. At that point things perked up. After snacks, we broke up into three smaller groups in different areas of the room, and that went over great. I wound up mostly chatting (in Japanese) with a Chinese guy who I believe came to Japan to attend college. We talked about a number of topics. He said that they study English starting in middle school, but that they only study it to pass a test in it, and they never get any opportunities to speak it. (He had a notebook handy where he would write down any English phrases he heard me say.) He asked a number of questions about the US, particularly about marriage. One question he asked was quite interesting: "I read in a book that people are very free in America. I wanted to ask if that was true...some authors base their books on facts, but some don't."
After a while, a Japanese lady next to him joined in and asked questions about what it was like learning Japanese and what we found difficult. We talked for a while about that. We all agreed that keigo (polite language) was very hard.
At the end of the meeting, I was given another bag of cookies as a reward for helping out.
When I got home, I spent a while putting a bunch of my journal entries in memories. So if there's anyone who wants to, say, find out what there is to do in Kyoto, you can check out the "Kyoto" section for my reports on what I've done. (The "Chiba" section includes Tokyo and anything else in the vicinity.) Just be warned that a lot of the more fannish entries are locked.
