As Japan plays host to a record influx of tourists, one of the country's more private attractions — the high-tech toilet — is becoming a must-have in luxury bathrooms worldwide.

With their warm seats and precision spray technology, bidet toilets are the norm in Japan, where more than 80% of homes have one, according to a government survey.

Now sales are surging abroad and especially in the United States, led by A-list bidet fans such as Drake, the Kardashians and Alexandria Ocasio-Cortez.
