The Higashiyama Walking Course in Takayama, Japan, is steeped in history, and this extends to its culinary traditions. Takayama has long been known for its abundance of high-quality ingredients, partly due to its location surrounded by mountains. The region is famous for its clean water and fertile soil, which contribute to the production of fresh vegetables and grains that are central to its dishes. Historically, due to the city's relative isolation, the locals developed preservation methods like salting, pickling, and fermenting, which are still reflected in local cuisine today.
