Christian Japan

I’ve been reading about the Japanese Warlord Era and a small part was about Christianity in Japan. It said that it grew in popularity even having a few Christian Daimyos on the island of Kyushu. I had two questions about this.

1. What is the best way to Christianize Japan without it keeping open to the world?

2. What would a Catholic Japan look like today and how would it affect history?
 
Now that's a tough one.

GURPS Alternate Earths, look up the "Shikaku-Mon" parallel. They have a suggested POD with St. Francis Xavier getting over his fever, then returning to Japan. The Jesuits have to be more successful without stepping on so many toes, and Christianity in Japan would very different....
