I'm very interested to learn about foreign religious influences in Japan, in particular Christianity. What is the general Japanese opinion of Christianity, if any? Is there a surplus of a particular denomination? Are certain parts of the country more exposed to Christianity than others? Have you had experiences with Japanese Christians or churches? Or maybe even experiences with Christians coming to Japan with the purpose of missionary work?

This whole topic seems to be practically non-existent in any website I go to about Japan, so I'm really interested to find out what you guys might know. Any information is helpful, even if I didn't ask it in one of my one million questions.

Thanks a bunch!

Very few Christians here..
but they have been coming here and trying to convert people for hundreds of years..
The old dude made this really good interview about religion in Japan http://www.youtube.com/watch?v=OAeXcPLeDMY

That was definitely an interesting video. Thanks for posting it! He was right in how the religious aspects of Japanese culture such as visiting shrines on New Years are so intertwined that people don't even see them as being religious activities. I love to talk philosophy, religion and the like so based on these videos it wouldn't seem that Japanese people get as easily offended over this subject. Do you think your average Japanese person would be okay with discussing religion? I would love to hear a different opinion on belief in god and the like with someone from Japan who just has a different paradigm than those in other countries.

May I suggest that you speak with a person who is a member of nichiren Buddhism
From the age of 16 until 32, Nichiren studied in numerous temples in Japan, especially Mt. Hiei (Enryaku-ji) and in his day the major centers of Buddhist study, in the Kyoto–Nara area. He eventually concluded that the highest teachings of Shakyamuni Buddha (563–483 BC) were to be found in the Lotus Sutra. The mantra he expounded on 28 April 1253, known as the Daimoku, Nam-Myo-Renge-Kyo, expresses his devotion to that body of teachings. During his lifetime, Nichiren stridently maintained that the contemporary teachings of Buddhism taught by other sects,particularly Nembutsu, Zen, Shingon, and Ritsu were mistaken in their interpretations of the correct path to enlightenment, and therefore refuted them publicly and vociferously. In doing so, he provoked the ire of the country's rulers and of the priests of the sects he criticized; he was subjected to persecution which included an attempted beheading and at least two exiles. Some Nichiren schools see the incident of the attempted beheading as marking a turning point in Nichiren's teaching, since Nichiren began inscribing the Gohonzon and wrote a number of major doctrinal treatises during his subsequent three-year exile on Sado Island in the Japan Sea. After a pardon and his return from exile, Nichiren moved to Mt. Minobu in today's Yamanashi Prefecture, where he and his disciples built a temple,
Kuon-ji Nichiren spent most of the rest of his life here training disciples.
