### ■ Background of Introduction The meltwater from the Northern Alps emerges as clear spring water in Azumino City, Nagano Prefecture, after 20 to 30 years. nana's green tea uses wasabi from Fujiya Wasabi Farm, grown with Azumino's spring water, in its regular menu 'stem wasabi'. This natural spring water is rich in oxygen, continuously flows 365 days a year, and maintains a constant temperature, creating a stable breeding environment suitable for fish farming. The same farm also cultivates salmon using this spring water. 'Azumino Salmon' raised in this environment is characterized by its elegant fattiness without any unpleasant odor and its tender texture. Impressed by the sophisticated taste and the fact that it is a domestic ingredient consistent with nana's green tea's concept, it was decided to be adopted for the first time by a restaurant chain.
