Waymo puts about 100 cars behind Japan's first commercial robotaxi service
The 2027 date Waymo, Nihon Kotsu and GO have set for public driverless trips in Tokyo depends on national and local permits the partners have yet to obtain, and on a fleet that only gradually reaches about 100 cars.
The Investor · Invest desk
What happened
- Waymo, Nihon Kotsu and GO have agreed to prepare a fully driverless ride-hailing service in Tokyo, with public trips targeted for 2027 in what would be Japan's first autonomous robotaxi operation.
- The service starts with an initial fleet and expands gradually to about 100 vehicles across key Tokyo neighborhoods, with bookings taken through the GO taxi app and through Waymo's own app.
- Waymo said the 2027 start is not a given, and depends on approval from national and local regulators plus completion of the technical validation it is running with its two Japanese partners.
- Waymo said it began operating in Tokyo in 2025, and its cars spent the following year driving the city autonomously with Nihon Kotsu crew members supervising from inside the vehicles.
Why it matters
- What it limits constraint The launch year sits on ministry timetables, so more vehicles and more test miles cannot pull 2027 forward.
- Who has to decide decision Nihon Kotsu has put its own crew members in the supervision seats of cars meant to cover shifts it expects not to fill, so the taxi operator is helping build its labor substitute.
- Who's exposed exposure Riders reach the driverless cars through the GO app they already use for taxis. That leaves the incumbent hailing platform deciding how much demand a 100-car fleet sees against conventional supply.
- What it sets up precedent A commercial driverless licence in Tokyo would be the first in Japan, and its terms become the template every other operator negotiates against.

About 100 cars is the whole of the fleet plan, and Waymo supplied the comparison: more than 500,000 rides a week across more than 15 US cities [10]. That works out to at most about 33,000 rides a week per city, or roughly 4,800 a day [16]. Split across 100 vehicles, Tokyo would need about 48 trips per car per day to carry the load of an average American city on Waymo's own books [17]. Because the count is more than 15 cities, the true per-city average sits below that, and so does the implied duty cycle.
From the initial announcement in December 2024 [8] to the earliest possible start in 2027 is about 25 months [18]. The companies say they are expanding local operations while working with government ministries on the permits and licences a driverless fleet needs to operate commercially [12].
Nihon Kotsu President Yasuharu Wakabayashi said the project could help maintain reliable transportation as Japan faces "future driver shortages" [9]. The country's aging population is expected to deepen the labor shortage [13]. The announcement does not say how large the shortfall is, or how many taxis Nihon Kotsu runs today [14]. Waymo co-chief executive Tekedra Mawakana said expanding to Tokyo with GO and Nihon Kotsu is "the next chapter" in the company's scaling effort [15].
The partners said in the Waymo blog post dated Monday, September 14 that the service is intended to operate commercially and not just as a limited pilot [3]. That sentence is written for ministries. A licence is required to charge for driverless trips; a supervised test can run without one.
The licence might arrive with a vehicle cap and an operating area, so that about 100 cars across key neighborhoods describes the permit as much as the ambition. Validation might run long and 2027 become 2028. Or the safety record carries the argument: Waymo claims its system is more than 15 times safer than a human driver, a figure Cryptopolitan said the company did not independently substantiate in its announcement [11].
In my view the first licence covers fewer than 100 cars, with 100 reached through renewals. If the ministries authorise the full fleet at the outset, that reading was wrong and validation was the binding item all along.
What to watch
- Any ministry decision text that names a vehicle cap or an operating area for the Tokyo licence.
- Whether Nihon Kotsu says how many crew members it has assigned to supervised runs, and for how long.
- Whether Waymo's weekly US ride count keeps climbing while the Tokyo validation programme runs.
