The document provides information about an upcoming event called the Yamathon organized by the International Volunteer Group to raise money for Oxfam Japan. It will involve teams walking or jogging between all 29 stations of the Yamanote train line in Tokyo within 12 hours while taking photos at each station. Funds raised will help provide relief for the drought crisis in Somalia. Participants are encouraged to register their 4-person teams, train in advance, and seek sponsorship to generate donations for the cause. Safety precautions are also outlined. An after-party will be held after the event.
