Is it possible to become a Buddhist monk in Japan ?

Question:

And live there for the rest of my life ? I do not have japanese nationality.

Answer:

Yes, it is certainly possible to become a Buddhist monk in Japan (or Korea, Thailand and other Buddhist countries) and live there the rest of your life.

However, you might not want to pack up your stuff and move to Japan right away. I recommend first that you begin Buddhist training (probably in the Zen tradition) with a Japanese Buddhist temple in your country. Most such temples have affiliations with temples in Japan where you can "transfer."

Also, unless you have considerable experience as a Buddhist practitioner, most teachers will not ordain you. It generally takes 2 or more years of serious, dedicated practice before a teacher will consider ordination as a monk.

Finally, you will need to learn Japanese reasonably well before you go to Japan. You will also needs sponsorship for your visa and will probably need to leave the country periodically to renew it.

All this is possible, if you feel a genuine calling.
