It's a surprise to see my niche being brought up on Hacker News! I read the site regularly, so it's a little flattering to be mentioned.

Gunkanjima was a fascinating place to explore, but there are countless other much smaller sites with their own mystique and rich history. The 'Royal House' and 'Red Villas' are among many that I have explored and documented.

Shikoku is one of the four main islands of Japan. It's not in any way 'forgotten' in the urbex sense, but as with most everywhere in Japan, it has many abandoned buildings and sites to find, as well as some good diving sites, I hear.
