The Nasu region of Tochigi Prefecture is the largest dairy producing area in Honshu, and there are numerous cheese factories in this part of the country. These factories have also put a focus on utilizing whey, the liquid remaining after milk has been curdled and strained during the cheese-making process – it's a byproduct that is often discarded elsewhere.
The Cheese and Whey Festival aims to shine a light on both industries, and includes the chance for attendees to taste and compare cheeses from factories across the country, sample dishes made with cheese and whey from popular restaurants, and even take part in a ricotta cheese making experience.
Admission to the event is free, but bring yen if you plan on purchasing food.
