i am gonna be free the whole of summer 2007 and I would like to get a summer job in Tokyo or Yokohama. Ideally, I would like to work in a NGO or charity organization because i don't need to earn money. I'm a Japanese teenager and i speak english. I've looked online but there isnt anything suitable for me because of my age and also because i can only work for a couple of months. Can anyone suggest anything?
