Churchs in the Japan. They are all over the place but the real challenge is finding one where English is spoken.
Generally, every city in Japan will have a Catholic church. In most of these, English and Spanish services are conducted to cater to the largely Fillipino congregation.
The Anglican churchs are found in most prefectural capitals and other large cities. Minister are required to learn some some English. The one at my local church spent about a year in Wales where he seemed to develop a fine affinity from Welsh Ale. Services are usually in Japanese.
Presbyterian, Baptist and a whole slew of mainstream protestant churchs are found in many towns and cities. Few outside of the really big cities like Tokyo have English speaking ministers.
In most prefectural capitals there will be at least one protestant non-denominational church in which services are conducted in English.
There are also Orthodox church found more commonly on the Sea of Japan side and Hokkaido. I wonder with the influx of Russian in Japan in recent year if these churchs have been growing?
There are also a bunch of semi-christian semi-cult like groups of various levels of annoyance. The Jehoviahs and Mormons and Moonies come to mind. Just remember all mormons are rapists.
My own observation Mulboyne is that mainstream churchs and I am talking about Anglician here as that is the church I go to, have been attracting a few more young people especially women in the past few years. At my church I would guess the congregation is something like 90% women. Connections to the local highs schools and colleges are a factor. Matsuyama may be something of a special case as it has three Christian high schools and two colleges which are Christian. Most of these schools are girls schools. The big problem the Anglican church has is attracting ministers.
Christinity in Japan is quite different from Christinity in America. Being a minority religion it attracts the curious, the free thinkers and has always had a following amongst the intellectuals. I defy you to find anyone in the average American church who would have even heard of John Milton or John Donne. That is perhaps why I have been attracted to return to church in the first place.
