With the upcoming 2020 Olympics in mind leading Japanese toilet-maker Toto Ltd. has recently introduced a new type of self-cleaning toilet for public restrooms, aiming to improve bathroom experiences for locals and foreign visitors to Japan.

"We're seeing a surge in inbound tourism," said Hirofumi Matsutake, a spokesperson at Fukuoka-based Toto.

The firm's study has found that Japan's high-tech toilets are popular among many non-Japanese people.
