[Niigata] Sado Island Gold Mine & Tarai Boat Experience & Niigata Kiyotsu Gorge Four-Day Tour - Group of 6 (Departure from Tokyo Ueno)

* World Cultural Heritage | Sado Kinzan Visit the Sado Kinzan, newly added to the UNESCO World Heritage List in 2024, and step into the hand-dug tunnels from the Edo period and the modern mine ruins from the Meiji era that have been preserved in their original state. Witness firsthand the starting point of Japan's modern industrial development. The iconic "Doyu-no-Warito" landscape, like a real-life version of the animated film "Castle in the Sky", is a famous spot that heritage and photography enthusiasts cannot miss. * Fairytale-like marine experience | Sado Tarai Boat Take a ride on the "Tarai Boat", Sado Island's most iconic traditional round wooden boat, and slowly move forward in the crystal-clear coastal waters. The azure sea flows under your feet, and the atmosphere, combined with the scenery of the fishing port and rocky shore, is like stepping into the dreamlike world of "Spirited Away", a classic experience unique to Sado Island that cannot be replicated. * Superb view coastline | Senkaku Bay Under
