Ishigakiyama Castle (solo trip)
How Solo-Friendly is Ishigakiyama Castle?
What makes it 77% Solo-Friendly: A solo traveler can hike the forest trail, linger among sixteenth-century ramparts, and take wide coastal photos; the only real drawback is the 40-minute steep climb and scarce shelter in bad weather.
Positives:

- Free admission: No entry fee lets you spend on extras like snacks or photos.
Challenges:
- Steep uphill trail: The climb takes 45 minutes and can be tiring without breaks.
- Limited signage in English: Most interpretive signs are in Japanese; use a trail map app.

The atmosphere here is amazing. Nature and history. Very beautiful but hard to access without transport. Take the bus
