Japan's famed cherry trees are getting old, but a new AI tool that assesses photos of the delicate pink and white flowers could help preserve them for future generations.

The "sakura" season is feverishly anticipated by locals and visitors alike, with the profusion of the stunning blossoms marking the start of spring.

But many of the trees are reaching 70 to 80 years old, well beyond their prime blooming age.

This means increasing costs to tend to the trees and maintain popular flowering spots.

To help authorities identify ailing specimens, brewing giant Kirin developed a tool called Sakura AI Camera.

It tells users the condition and the age of the trees based on photos they take with their smartphones and upload them to a website.

A five-point scale -- only available in Japanese for now -- ranges from "very healthy" to "worrying".

A tree with healthy flowers blooming densely all the way to the tips of the branches gets top marks.

The artificial intelligence tool has been trained using 5,000 images of cherry trees with the help of experts.

The photos are then mapped on the Sakura AI Camera website with details such as tree condition and location.

"We heard that the preservation of sakura requires manpower and money and that it's difficult to gather information," Risa Shioda from Kirin told AFP.

"I think we can contribute by making it easier to plan for conservation," she said.

About 20,000 photos have been collected since the launch last month, with the data available online for free for local authorities.

- Worth a million -

According to Tokyo's Meguro Ward, famous for its riverbanks lined with cherry trees, replanting a new one costs around one million yen ($6,800).

Hiroyuki Wada of the Japan Tree Doctors Association, who inspects cherry trees in major spots in Tokyo, helped supervise the AI tool.

He said he hopes that it will help experts study the environmental reasons behind the degradation of some of the trees he sees.

In part, he blames climate change.

"I'm very worried. Changes in the environment are usually gradual, but now it's visible," he told AFP.

"There are impacts from the heat, and of course the lack of rainfall," he said.

"The age of the trees naturally makes the situation more serious," he added.

Japan's weather agency said in January that last year was the hottest since records began, like other nations.

Kirin began donating some of its profits for the preservation of cherry trees last year, as a way to "pay back" to the communities.

Cherry blossoms symbolize the fragility of life in Japanese culture as full blooms only last about a week before the petals start falling off trees.

The season is also considered one of change as it marks the start of the new business year, with many university graduates starting their first full-time jobs and older colleagues shifting to new positions.

President Donald Trump will join executives from some of the largest US tech and energy companies for a summit in Pittsburgh on Tuesday as the administration prepares fresh measures to power the US expansion of artificial intelligence.

Top economic rivals US and China are locked in a technological arms race over who can dominate AI as the technology takes on increasing importance everywhere from corporate boardrooms to the battlefield.

The Energy and Innovation Summit at Carnegie Mellon University is expected to bring tech executives and officials from top energy and tech firms including Meta, Microsoft, Alphabet and Exxon Mobil to discuss how to position the US as a leader in AI. Trump will use the summit - put together by US Senator Dave McCormick, a Republican ally from Pennsylvania - to announce some $70 billion in artificial intelligence and energy investments in the state, Reuters reported.

Big Tech is scrambling to secure vast amounts of electricity supplies to power the energy-guzzling data centers needed for its rapid expansion of artificial intelligence. Companies began announcing their plans in early on Tuesday, with Google inking a $3 billion electricity deal and CoreWeave touting a $6 billion AI data center.

Google will invest $25 billion in regional data centers, while FirstEnergy will invest $15 billion in Pennsylvania's energy grid, Semafor reported. The CEOs expected to attend include Khaldoon Al-Mubarak of Mubadala, Rene Haas of Arm, Larry Fink of BlackRock, Darren Woods of ExxonMobil, Brendan Bechtel of Bechtel and Dario Amodei of Anthropic. The White House is considering executive actions in the coming weeks to make it easier for power-generating projects to connect to the grid and also provide federal land on which to build the data centers needed to expand AI technology, Reuters previously reported.

The administration is also weighing streamlining permitting for data centers by creating a nationwide Clean Water Act permit, rather than requiring companies to seek permits on a state-by-state basis.

Mike Sommers, head of the influential American Petroleum Institute, said executive action is welcomed to unlock the energy needed to power the data centers, but a more durable solution is needed.

"Real durable permitting reform requires an act of Congress, not just an executive order," Sommers said in an interview with Reuters. Trump ordered his administration in January to produce an AI Action Plan that would make "America the world capital in artificial intelligence" and reduce regulatory barriers to its rapid expansion.

That report, which includes input from the National Security Council, is due by July 23. The White House is considering making July 23 "AI Action Day" to draw attention to the report and demonstrate its commitment to expanding the industry, Reuters has reported.

US power demand is hitting record highs this year after nearly two decades of stagnation as AI and cloud computing data centers balloon in numbers and size across the country. The demand is also leading to unprecedented deals between the power industry and technology companies, including the attempted restart of the Three Mile Island nuclear power plant in Pennsylvania between Constellation Energy and Microsoft.

The surge has led to concerns about power shortages that threaten to raise electricity bills and increase the risk of blackouts, while slowing Big Tech in its global race against countries like China to dominate artificial intelligence.
