Ozawa Shuzo was founded in 1702 and is the oldest sake brewery in Tokyo Prefecture. The brewery is in the town of Okutama, which abounds with lush natural beauty despite being part of the Tokyo metropolitan area. Their Sawanoi brand takes its name from the neighboring Sawai area, known for its pristine spring water. The brewery’s water source is perfect for brewing sake, originating deep in Chichibu Paleozoic rock layers, and emerging as a natural spring in a cave.
