Going to japan over the winter holidays

Hi!
My name is Thom, 20 years old and I'm planning a trip to japan in the end of December.
I'm planning on staying for 2 weeks, but the thing is that I don't want to live in a hotel. Instead I'd like to live with a japanese familly or person so that I can learn more about the japanese customs and so on.

Much obliged
Thom Orahim

Unless you are part of somesort of cultural exchange program, most families don't take in random strangers. Same for regular strangers you meet.

If you want to interact with other people living in Japan, try youth hostels etc, though its not exactly living with a family, you might run into people there.

There are organizations that do this, even JNTO I think can help with setting up a one night homestay. do a google search for 'homestay japan' and watch the results roll in. Also try WWOOF Japan, which is 'Willing Workers on Organic Farms', you'd have to actually work, I guess, but it looks interesting.
