Japan uses Uber, but Grab is not available in the country (Grab is primarily a Southeast Asian service). However, Uber in Japan works differently than in the US or Europe. Due to strict transport laws, Uber functions almost entirely as a taxi-hailing service. When you request a ride, the app dispatches a licensed, professional taxi from a local partner company like Hinomaru or Nihon Kotsu. You pay the standard metered taxi fare plus a small "app arrangement fee." While Uber is convenient for English speakers, the most popular and widely used ride-hailing app in Japan is actually Go (formerly JapanTaxi). It has a much larger fleet of cars, especially in smaller cities. Another popular option is S.Ride. If you are in Tokyo, Uber is great for booking "Uber Black" luxury cars, but for everyday travel, most locals use the Go app or simply hail a taxi on the street with a hand wave, as they are ubiquitous and incredibly clean.
