High Tech Gadgets found in Japan

Actually... this is an awkward topic :p In our last trip to Japan, we found this high tech toilet (bidet, hygiene seat) in the spa bathroom. We tried it, separately, and it was a nice surprise. It's a rear wash. It was refreshing and clean feeling. After a little research, it's supposed to make you healthier too. It's amazing what you find in other part of the earth!
