Ishigakiyama Castle, Hill castle in Hayakawa, Japan.
The castle features extensive stone walls and observation points offering views of Odawara Castle, Sagami Bay, and on clear days, Tokyo Skytree.
Toyotomi Hideyoshi established this fortress in 1590 during the Siege of Odawara, mobilizing 40,000 workers who completed the construction within 80 days.
The castle became the first stone fortification in the Kanto region, demonstrating advanced engineering techniques through its stone masonry and strategic defensive layout.
Visitors can reach the castle through a 50-minute walk from Hayakawa Station or take a longer route from Iriuda Station on the Hakone Tozan Railway.
The castle earned its nickname 'One-Night Castle' after Hideyoshi arranged wooden frames and fences at the mountaintop, then cleared surrounding trees in a single night.
