Former Yamagawa Salt Factory Site is a cool spot to check out in Ibusuki, Japan. It used to be a bustling salt factory back in the day, but now it's a neat historical site to stroll around. You can learn about the area's salt-making history and snap some cool pics while you're at it. Plus, it's right by Tamatebako Onsen, so you can easily swing by on your way to soak in some hot springs.
