We’re four foreigners attempting a 100km walk to raise ¥300,000 for some of the world's poorest people. Why? Well, we could easily just take your money and spend it on Mexican food or beer but we'd rather give it to Oxfam. On May 22 we'll begin our hike from Odawara City to Lake Yamanaka near Mt Fuji for the Oxfam Trailwalker Challenge.
