A Hidden Edo Wrapped in Pleasant Nature

• It's a bit difficult to find the mountain castle site surrounded by rich greenery
• On the walking paths, you can encounter the chirping of wild birds and fruit-bearing trees
• The idyllic landscape spreads out, making you forget about time

A Small Adventure to Explore History

• It's worth crossing the animal deterrent fence and exploring without sparing effort
