The always interesting Tokyo Reporter published a story I saw this morning about a guy wearing eyeglasses that concealed a hidden camera in Tarumi-ku, Kobe. The werido was arrested on the 29th after another customer called 119 on him. According to the articles, this werido is a hospital worker from Nishinomiya--my town! He stated that he wanted to take videos of guys in the bath.
The supersento in question is Taihei no Yu. I have only been there once more than 5 years ago. There is no natural hot spring there, but it does have a superb outdoor bath with great views of the ocean and, I think, the Awaji Bridge.
So weridos like this are an issue for any sento or onsen. I have always felt that if a person got any sort of pleasure out of seeing my semi-overweight, hairy body there was not so much that I could do about it. I'm not going to deny myself something I enjoy because maybe, sometime, someone checked me out while I was in the tub. Who cares! How am I ever going to know, anyhow?
However, cameras or inappropriate flirting (for the last of a better word) are not anything that belongs in a public bathhouse. Unless, it's a "bathhouse" where flirting and more are expected and even in a "bathhouse" like that cameras are a big no-no!
So what's the take-away? Stuff like this happens but why worry about it so much that it effects your own personal enjoyment. It's a good idea to keep your eye out for weridos like this guy, but I wouldn't be trying too hard.
