Japan has been working to convert its traditional squat toilets to Western-style commodes to accommodate the growing influx of foreign tourists.
With many foreign visitors puzzled over how to use squat toilets and even shunning them as "unsanitary," the government has been promoting toilet modernization in the run-up to the 2020 Olympics, when it aims to welcome 40 million inbound travelers during the year.
The nation's major tourist spots have around 4,000 public toilets. A survey by the Japan Tourism Agency last year showed 58 percent were Western-style and 42 percent were squat toilets.
