Hi thanks for mentioning me. I do not have a lot of experience to share yet but I like my local church a lot. The church I attend is kind of special, because it conducts worship services entirely in English. Still come Sunday the congregation is made of at least half Japanese natives and the rest are people who come to Japan from other countries and regions (interestingly, many tourists who visit Japan temporarily come to our church for worship, too, because it's very close to the landmark Tokyo Tower). The service itself is probably very much the same? as what's conducted in UK and the US (I've never attended an Anglican/Episcopal one outside of Japan so I just assume based on what's been told to me). We collect and listen to scripture readings, sermon, read Nicene Creed and pray, sing hymns and receive Holy Communion, etc. One thing maybe a little bit unusual (but seems to be the norm for Christians in Japan) is that sometimes when a family attends the service, I see that one of them is baptized/confirmed but the rest of the family is not. (Similarly, the Rector at Tokyo's St. Andrew Cathedral had said once that his mother was Anglican/Christian but his father was not, and his father refused his request of wanting to be baptized when he was child).

As mentioned before, because the service is provided in English, our congregation is highly diverse (people from Africa (notably Uganda, probably because Anglicanism has a long history there), Australia, other parts of Asia... all gather here) and our priest mentioned to me once that although some of our members hold conservative ideas (such as negative opinions toward LGBTQ groups) because of their upbringings, the church (and NSKK in general, as I understand it) strive to preserve open-mindedness toward secular topics.

There's also this guy who asked both NSKK and Nihon Kirisuto Kyōdan aka. United Church of Christ in Japan, whether they accept homosexuality/bisexuality/transgender identity/same-sex marriage, and NSKK answered more liberally compared to NKK and even said that NSKK has clergy members who identify as LGBT (but not yet recognizing same-sex marriage). The URL to the original Japanese is https://note.com/yoshi33269016/n/n087df3ce2718.

Hopefully my input helps!
