I want to know the answer to the following question:
When did Xavier try to convert Japan to Christianity?
All the background I'm provided with is that "Xavier further describes the honour and manners of the people: "I fancy that there are no people in the world more punctilious about their honour than the Japanese, for they will not put up with a single insult or even a word spoken in anger."". Is that enough to answer the question?
Answer: no
