Alphabet-owned Waymo announced Monday that it will start testing its autonomous vehicles in Tokyo in early 2025, the company’s first step toward international expansion.
Waymo hasn’t committed to start commercial service in Tokyo yet, but the robotaxi developer will partner with Japan’s largest taxi operator, Nihon Kotsu, and taxi app GO to start testing its Jaguar I-PACE vehicles in Tokyo’s streets.
To start, Nihon Kotsu drivers will manually operate the Waymo vehicles to map key areas of the Japanese capital, including Minato, Shinjuku, Shibuya, Chiyoda, Chūō, Shinagawa, and Kōtō.
Data from the manned test drives will help train the company’s AI systems. Waymo will also test its robotaxis on a closed course in the U.S. built to mimic driving conditions in Japan.
This is the first phase of the partnerships, which will last several quarters, Waymo told CNBC, adding that it expects to remain in Japan for an extended period.
“Our upcoming road trip to Tokyo gives us the chance to work alongside local partners, government officials, and community groups to understand the new landscape,” Waymo said in a statement. “We’ll learn how Waymo can serve Tokyo’s residents and become a beneficial part of the city’s transportation ecosystem.”
Nihon Kotsu will oversee the management and servicing of Waymo’s vehicles in Japan, the companies said.
Waymo announced a series of expansions across the U.S. in 2024. Earlier this month, the company announced new testing in Miami in 2025, it made its driverless ride hail service available across Los Angeles in November, and in September, it announced planned expansions into Austin and Atlanta in partnership with Uber.
The move into Japan marks the company’s first in a left-hand traffic market.
Both the Japanese national government and Tokyo Metropolitan government see driverless technology as a potential boon to the country’s aging population, according to research by the World Economic Forum.
Tokyo has designated certain areas as “test zones” for self-driving cars hoping to hasten the arrival of safe driverless transportation systems there.
Several developers are working on autonomous vehicles in Japan, including local startup Tier IV and ZMP, a robotics company that is testing delivery vehicles and buses in Tokyo. Monet Technologies, which is partly owned by Toyota, announced plans to test a self-driving taxi service in Tokyo’s Odaiba district earlier this year.
Waymo’s Japan expansion announcement comes a week after General Motors announced it was abandoning its Cruise robotaxi division. Honda, an outside investor in Cruise, told CNBC that it aimed to launch a driverless ride-hail service in Japan in early 2026 but would re-assess those plans and make adjustments if needed.
Prior to GM’s retreat from robotaxis, Cruise had been one of Waymo’s primary domestic competitors.
The letters AI, which stands for “artificial intelligence,” stand at the Amazon Web Services booth at the Hannover Messe industrial trade fair in Hannover, Germany, on March 31, 2025.
Amazon said Wednesday that its cloud division has developed hardware to cool down next-generation Nvidia graphics processing units that are used for artificial intelligence workloads.
Nvidia’s GPUs, which have powered the generative AI boom, require massive amounts of energy. That means companies using the processors need additional equipment to cool them down.
Amazon considered erecting data centers that could accommodate widespread liquid cooling to make the most of these power-hungry Nvidia GPUs. But that process would have taken too long, and commercially available equipment wouldn’t have worked, Dave Brown, vice president of compute and machine learning services at Amazon Web Services, said in a video posted to YouTube.
“They would take up too much data center floor space or increase water usage substantially,” Brown said. “And while some of these solutions could work for lower volumes at other providers, they simply wouldn’t be enough liquid-cooling capacity to support our scale.”
Rather, Amazon engineers conceived of the In-Row Heat Exchanger, or IRHX, that can be plugged into existing and new data centers. More traditional air cooling was sufficient for previous generations of Nvidia chips.
Customers can now access the AWS service as computing instances that go by the name P6e, Brown wrote in a blog post. The new systems accompany Nvidia’s design for dense computing power. Nvidia’s GB200 NVL72 packs a single rack with 72 Nvidia Blackwell GPUs that are wired together to train and run large AI models.
Computing clusters based on Nvidia’s GB200 NVL72 have previously been available through Microsoft or CoreWeave. AWS is the world’s largest supplier of cloud infrastructure.
Amazon has rolled out its own infrastructure hardware in the past. The company has custom chips for general-purpose computing and for AI, and designed its own storage servers and networking routers. In running homegrown hardware, Amazon depends less on third-party suppliers, which can benefit the company’s bottom line. In the first quarter, AWS delivered the widest operating margin since at least 2014, and the unit is responsible for most of Amazon’s net income.
Microsoft, the second largest cloud provider, has followed Amazon’s lead and made strides in chip development. In 2023, the company designed its own systems called Sidekicks to cool the Maia AI chips it developed.

Bitcoin hit a fresh record on Wednesday afternoon as an Nvidia-led rally in equities helped push the price of the cryptocurrency higher into the stock market close.
The price of bitcoin was last up 1.9%, trading at $110,947.49, according to Coin Metrics. Just before 4:00 p.m. ET, it hit a high of $112,052.24, surpassing its May 22 record of $111,999.
The flagship cryptocurrency has been trading in a tight range for several weeks despite billions of dollars flowing into bitcoin exchange traded funds. Bitcoin purchases by public companies outpaced ETF inflows in the second quarter. Still, bitcoin is up just 2% in the past month.

Bitcoin climbs above $112,000
On Wednesday, tech stocks rallied as Nvidia became the first company to briefly touch $4 trillion in market capitalization. In the same session, investors appeared to shrug off the latest tariff developments from President Donald Trump. The tech-heavy Nasdaq Composite notched a record close.
While institutions broadly have embraced bitcoin’s “digital gold” narrative, it is still a risk asset that rises and falls alongside stocks depending on what’s driving investor sentiment. When the market is in risk-on mode and investors buy growth-oriented assets like tech stocks, bitcoin and crypto tend to rally with them.
Investors have been expecting bitcoin to reach new records in the second half of the year as corporate treasuries accelerate their bitcoin buying sprees and Congress gets closer to passing crypto legislation.

Perplexity AI on Wednesday launched a new artificial intelligence-powered web browser called Comet in the startup’s latest effort to compete in the consumer internet market against companies like Google and Microsoft.
Comet will allow users to connect with enterprise applications like Slack and ask complex questions via voice and text, according to a brief demo video Perplexity released on Wednesday.
The browser is available to Perplexity Max subscribers, and the company said invite-only access will roll out to a waitlist over the summer. Perplexity Max costs users $200 per month.
“We built Comet to let the internet do what it has been begging to do: to amplify our intelligence,” Perplexity wrote in a blog post on Wednesday.
Perplexity is best known for its AI-powered search engine that gives users simple answers to questions and links out to the original source material on the web. After the company was accused of plagiarizing content from media outlets, it launched a revenue-sharing model with publishers last year.
In May, Perplexity was in late-stage talks to raise $500 million at a $14 billion valuation, a source familiar confirmed to CNBC. The startup was also approached by Meta earlier this year about a potential acquisition, but the companies did not finalize a deal.
“We will continue to launch new features and functionality for Comet, improve experiences based on your feedback, and focus relentlessly–as we always have–on building accurate and trustworthy AI that fuels human curiosity,” Perplexity said Wednesday.
