The owner of Hipopo Papa Cafe on Japan’s Hayashizaki Matsue Coast really does take pride in his restaurant bathroom. In fact, he believes that a bathroom is an investment which can pay back dividends. Which is why he has reportedly spent almost $270,000 installing an aquarium behind three walls of the restaurant’s toilet.
The toilet is designated for women, but if the restaurant is not busy, the staff will bring any customer to the back to admire the marine views. When customers first walk back, it appears that the white toilet is floating in a green undersea world. You'll find that when you sit down, you’re likely to make eye contact with an exotic fish or perhaps even a turtle.
The owner of the restaurant apparently spent years and several attempts trying to recreate the sensation of floating in the ocean while on a toilet. The final product has been around for about 12 years and has proven to be one of the most popular tourist attractions in the area.
