The Yazu Town Marathon is a community road race held each October in the small town of Yazu in eastern Tottori Prefecture, Japan. Runners pick from 10K, 5K, 3K and 2K courses that thread through the town, with a family division that costs nothing to enter. The race is named after Yazu native Koichi Morishita, the marathon silver medalist at the Barcelona Olympics, who ran these same roads as an elementary and junior high school pupil, and Mexico Olympics silver medalist Kenji Kimihara is expected to take part. Entry costs ¥2,500 for adults and ¥1,000 for elementary, junior high and senior high school students. The day is a relaxed, local affair built around the town hall, with mild autumn weather, roughly 7 hours of sunshine and only light rainfall typical for the month.

The family division is a free entry category created so that parents and children can take part together without an entry fee. Check the official town page or the Runnet entry page for the age rules and which distance the family division uses.
October in Yazu is mild and comfortable for running. Three year averages put temperatures between about 14.5°C and 22.2°C, with roughly 7 hours 11 minutes of sunshine a day, light rainfall of around 5.6 mm and a light breeze. Humidity sits near 80 percent, so allow for it if you are not used to running in damp air.
The event is built around running, and the shorter 2K and 3K courses are the most relaxed options for anyone who wants to take it steadily. If you are unsure whether walking is permitted, ask the organiser before you enter.
