Torafugu are cultivated using onsen water that wells up in the town of Nakagawa. It is known that pufferfish raised in hot spring water have approximately 30% extra umami (fifth basic food taste) ingredients. The taste of these puffer fish is even richer than those produced in the sea. This means there is no doubt that you can savor a taste overflowing with luxury! You can try onsen torafugu in the onsen facilities and restaurants in the town. Please appreciate the taste of torafugu when you visit Nakagawa!
