The Japanese and Suzuki resistance at large was as a result of the Buddha's strength that was taking over country by country. Indeed, the Japanese reasoned that there were already many gods that were highly esteemed and worshiped in Japan and hence there was no need to embrace the laws of Christianity. The Buddhist also rejected Christianity as a result of its insistence on worshipping one God rather than following the Japanese process of worship where the ministers or rather gods should be esteemed first before honoring the superior one.
The Japanese also rejected Christianity because of their way of punishment where they stressed death as a form of punishment. However, the Buddhist stressed and believed that the kind of punishment should be the curse of the heavens. No matter how the strategy of the Jesus missionaries uses accommodation as a source of spreading the Christianity, it proofed harder because of cultural difference.
The accommodation method was limited to the manners, and the missionaries were not willing to compromise the Catholic doctrines. Indeed, there was a failing strategy since Japanese; religious beliefs required a foreigner to fit themselves to the standards of Japanese customs. I think that the Christians even if they could be more accommodating, it could still be hard to maintain their integrity as Christians.
There were public anti-Christian pronouncements that warned the Japanese population against any form of forcefully converting the Japanese to Christians. The hegemon also considered that Christians were conjuring the Japanese into Christianity. The comparison that existed between the Christians and Buddhist was a significant threat to the spread of Christianity by the early missionaries.
