For my CIP, I went to a local shogi club in Kyoto and played/learned shogi. I first visited the club and told them I was interested. Then, I came back the next week to start. Throughout my time there I learned some shogi strategies and played several times against the people in the club. Since few people spoke English, I mainly used Japanese. I also borrowed and read a book to aid with my practice.
One of the first things I noticed was a lack of keigo usage. Even the younger kids just used です/ます form when speaking to adults. Meanwhile, the adults mostly used casual form. I believe this was due to the nature of the club. Specifically, senpai and kōhai relations weren’t really about age so much as skill. Thus, some of the younger kids didn’t use honorific forms because they were actually better than the older players.
I learned a lot of shogi specific vocabulary from the club. I think it may have been harder due to the fact that shogi terms aren’t exactly used in everyday conversation. This required me to actually review some of these terms before I went to the club. However, it was an enjoyable experience because, in between games, we would review what went wrong and where I could improve. As someone who has played a lot of chess, that part of the process was very familiar.
The best advice I can give to others is to find a CIP that isn’t as skill oriented. Unless you already do the activity at home/school, learning something from scratch is a very difficult process. Especially, learning in a non-native language. For me, playing chess allowed me to pick up shogi concepts quicker, but my CIP eventually became a chore. I had to spend time practicing in order to eventually win, but, when I became busy, practice was difficult. So, when I would go back to the club it would be the same result of me losing the entire time. As such, I think a more social oriented CIP could lead to a better experience.
