If you’re visiting Nagano and looking to discover a lesser-known but fascinating aspect of Japanese culinary tradition, the Agar Factory Tour and Tasting Experience at Chino City offers a surprisingly engaging glimpse into the world of agar—an ingredient often overlooked outside Japan.
This tour promises a mix of educational insights, a behind-the-scenes look at local craftsmanship, and a chance to taste and explore how this versatile gel is made and used.
