Thanks for your valuable feedback!
Since prices in the U.S. are generally higher than in Japan, I thought taxis in Japan might seem relatively affordable.
You can take a taxi in Japan starting from about $4.31. The fare then increases based on the distance traveled.
I also wonder if paying with cash makes some travelers nervous because they don't know how much the final fare will be.
That's why I was thinking that if people could pay with USDT, USDC, or JPYC, they might feel more comfortable using taxis without worrying about payment.
