Even though Japan had accepted Catholic very early, the Christianity could not be approved by the Government.

For Koreans, the Protestantism and America was considered as a savior at that time.

Wow, I didn't know about that. So, that's why Christianity became rapmant in Korea. In the same context, I personally think the reason why Japan has no specific national religion is that they've never experienced any outside pressure because Japan is an island country. So naturally, they don't have to unite or stand up to foreign intrusion, and they started to get focused on their folk religions. Well, it was an interesting story about Korea's Christianity. Thank you^^
