- Can I walk to the 4th Battery ruins directly after landing on Tomogashima?
- Yes, but expect a fairly long uphill walk on island paths from the pier. Wear proper shoes, because sections around the ruins can be uneven and slippery after rain.
- Is the Episode 6 angle easy to match at the 4th Battery ruins?
- It is fairly recognizable once you reach the area, but vegetation and safety features can change the exact sightline. Bringing the frame on your phone helps a lot when comparing the path and coastline.
- Are there signs, facilities, or restrictions I should know before visiting this spot?
- The island has guidance signs around major ruins, but facilities are limited compared with the mainland, so bring water and check ferry times carefully. As a historic ruin site, visitors should stay on marked paths and avoid climbing restricted structures.
