TOKYO (AP) — Japan's nuclear watchdog said Wednesday it is scrapping the safety screening for two reactors at the Hamaoka nuclear power plant in central Japan, after its operator was found to have fabricated data about earthquake risks.
It was a setback to Japan's attempts to accelerate nucler reactor restarts. Less than a quarter of commercial nuclear reactors are operational in the wake of the 2011 Fukushima Daiichi meltdowns, but rising energy costs and pressure to reduce carbon emissions have pushed the government to prioritize nuclear power.
Chubu Electric Power Co. had applied for safety screening to resume operations at the No. 3 and 4 reactors at the Hamaoka plant in 2014 and 2015. Two other reactors at the plant are being decommissioned, and a fifth is idle.
The plant, about 200 kilometers (125 miles) west of Tokyo, is located on a coastal area known for potential risks from so-called Nankai Trough megaquakes.
The Nuclear Regulation Authority said it started an internal investigation last February, after receiving a tip from a whistleblower that the utility had for years provided fabricated data that underestimated potential seismic risks.
The regulator suspended the screening for the reactors after it confirmed the falsification and the utility acknowledged the fabrication in mid-December, said Shinsuke Yamanaka, the watchdog's chair. The NRA is also considering inspecting the utility headquarters.
“Ensuring safety is the first and foremost responsibility for nuclear plant operators," Yamanaka said, adding that seismic data was clearly fabricated. “It is outrageous and it's a serious challenge to safety regulation.”
The scandal surfaced Monday when Chubu Electric President Kingo Hayashi acknowledged that workers at the utility used inappropriate seismic data with an alleged intention to underestimate seismic risks. He apologized and pledged to establish an independent panel for investigation.
The screening, including data that had been approved earlier, would have to start from scratch or possibly be rejected entirely, Yamanaka said. The NRA will decide on the case next week, without waiting for the utility's probe results, he said.
Public opinion in Japan remains divided due to lingering safety concerns after the 2011 Fukushima Daiichi meltdowns.
Of Japan's 57 commercial reactors, 13 are currently in operation, 20 are offline and 24 others are being decommissioned, according to NRA.

CAIRO (AP) — Iranians began to regain internet access on Wednesday after authorities ended a monthslong shutdown. But users said service was slow and spotty in some areas, with apps like YouTube and Instagram heavily restricted, as they were before the cutoff began during nationwide protests in January.
Authorities justified the outage as a military imperative after the United States and Israel attacked Iran on Feb. 28. Their decision to lift some restrictions this week came as negotiators appeared to be closing in on a more permanent truce. But many Iranians feared access could be cut off again at a moment's notice.
Internet tracking company Netblocks said Iran’s connectivity, which measures the ability of devices to connect to the internet, is at around 86% of capacity from before the cutoff. Internet analysis firm Kentik said internet traffic, which measures the amount of data transferred and is a good illustration of usage, was at around 40%.
Amir Rashidi, an Iranian cybersecurity analyst, said there were still widespread disruptions. “It's too early to say the shutdown is over,” he wrote on X.
Iran’s roughly 90 million people have been cut off from the internet for most of 2026, one of the world’s longest and strictest national shutdowns. Young people with online careers saw their incomes evaporate. Job losses and the closure of online businesses added to the war's steep economic costs.
The cutoff made it difficult for Iranian families to communicate through months of unrest and war. At some points, phone lines were also cut off, though they were later restored.
A woman living in Tehran said that for months she was barely able to speak to her sons living abroad. She couldn't believe authorities had restored access, saying she had assumed they would find some justification to prolong the outage.
A taxi driver said service was restored but weak. He expressed hope it would improve so he could use messaging apps with family and friends. Both spoke on condition of anonymity for security reasons.
Prices spiked during the shutdown, with residents in Tehran at times paying around $7.50 per gigabyte. Prices are back down to around $2.25 for 30 gigabytes, roughly where they were before the protests.
Even then, Iran tightly controlled access to popular social media sites, leading many to rely on virtual private networks, or VPNs. The cost of those workarounds soared during the shutdown, making them unaffordable for many as the economy was battered.
Businesses have started reappearing online, announcing their return with posts on sites like Instagram and Telegram.
A gamer and tech influencer in the central city of Isfahan said the shutdown had caused him to lose a lot of his audience on YouTube and Instagram, where he had spent years building up a large following.
“All my views and interactions are way down. I’ve been erased from the algorithm,” he said in a voice note sent by WhatsApp, adding that his internet connection was still slower than before the shutdown.
“The situation is such that many content producers have had their income reduced to zero, have moved on to other jobs, or have been forced to sell their equipment to survive,” he said. He spoke on condition of anonymity for fear of reprisal.
Iranian authorities first shut down the internet in January during mass anti-government protests that were eventually stamped out in a violent crackdown. Thousands of people were killed and tens of thousands detained.
That cutoff was just starting to ease when the government imposed a complete internet blackout after the start of the war, when U.S. and Israeli strikes killed Iran's supreme leader and other top officials.
The government faced criticism for the prolonged shutdown, which caused even more harm to an economy devastated by inflation, strikes on key industries and a U.S. blockade on Iranian ports.
The internet cutoff cost an estimated $30-40 million daily, with indirect losses likely twice that much, a member of Iran’s Chamber of Commerce, Afshin Kolahi, told a local newspaper last month. About 10 million people have jobs that depend on internet connectivity, according to Communications Minister Sattar Hashemi.
Iranians still had access to a national net, but that has a far narrower reach, and users complained of poor service and heavy censorship. Senior government officials are given SIM cards granting them access to the global internet. Under pressure, the government expanded access to the SIM cards to some professions during the shutdown.
