Japan shows off futuristic 'railgun' at defense expo
Instead of using gunpowder to shoot an artillery shell, railgun technology uses electromagnetic energy to fire off a projectile along a set of rails at ultra-high velocity
As Japan's biggest defense exhibition kicked off this week, visitors got a close-up look at a model of its futuristic "railgun" that its makers hope will be able to shoot down hypersonic missiles.
Instead of gunpowder, railgun technology uses electromagnetic energy to fire a projectile along a set of rails at ultra-high velocity.
The round will then in theory destroy the target, which could be an enemy ship, drone or incoming ballistic missile, solely with its vast kinetic energy.
Other countries, including the United States, China, France and Germany, are also developing the technology, but Japan's navy last year claimed a world first by test-firing a railgun on a ship.
"A railgun is a gun of the future that fires bullets with electrical energy, unlike conventional artillery," an official from the Acquisition, Technology and Logistics Agency (ATLA) within Japan's Ministry of Defense told AFP.
"It is expected that threats that can only be dealt with by railguns will emerge in the future," said the official, who did not want to be named.
The three-day DSEI Japan Conference defense fair, which began on Wednesday, comes as Japan adopts a more assertive defence policy and looks to sell more military equipment to other countries.
In particular, Japan's Mitsubishi Heavy Industries (MHI) and Germany's Thyssen Krupp Marine Systems (TKMS) are competing for a major contract to supply the Australian navy with new warships.
Winning the multi-billion-dollar Project Sea 3000 contract to supply Australia with Mogami-class frigates would be Japan's largest postwar military export order, according to Japanese media.

Chinese tourists returning to Japan with new travel style
KYODO NEWS - 5 minutes ago - 12:39 | All, Japan, Travel/Tourism Chinese tourists are driving a recent surge in inbound travel to Japan, with arrivals now exceeding pre-pandemic 2019 levels, though their travel habits are shifting noticeably. Previously, Chinese tourism in Japan was defined by large group tours and shopping sprees known as "bakugai." Nowadays, however, more travelers are seeking immersive experiences related to Japanese cuisine, culture and scenery, according to the Japan National Tourism Organization. A total of 3.13 million Chinese travelers visited Japan in the first four months of this year, topping the 2.89 million recorded during the same period in 2019. While the number of visitors from China was slow to rebound after the pandemic, arrivals have steadily increased since the Chinese government lifted its ban on group tours to Japan in 2023, reaching 2.42 million that year and 6.98 million in 2024. Growth has continued into 2025, with year-on-year increases of 135.7 percent in January, 57.3 percent in February, 46.2 percent in March and 43.4 percent in April. The shift in travel preferences is partly driven by Chinese travelers in their 30s and 40s, many of whom have visited Japan before, now choosing family trips with their children over group tours. The JNTO is working to better target that market, including opening an account on a popular Chinese social media platform last fall. Meanwhile, visitor numbers from Hong Kong, which are tallied separately from mainland China, increased 30.8 percent in January from the previous year but declined 5 percent in February and 9.9 percent in March. A Japanese manga predicting a major disaster in Japan this July is believed to have discouraged travel. Posts about the manga "The Future I Saw" went viral after some claimed that its artist, Ryo Tatsuki, also predicted the 2011 earthquake and tsunami in northeastern Japan, among other events. Nevertheless, April saw a strong rebound, marking a 42.9 percent increase from the previous year. At a press conference earlier this month, Japan Tourism Agency Commissioner Naoya Haraikawa dismissed the concerns, saying, "I believe they currently have no real impact."

Trump Hails Nippon Steel as ‘Great Partner' as Deal Awaits Approval
Reuters U.S. President Donald Trump delivers remarks at U.S. Steel Corporation–Irvin Works in West Mifflin, Pennsylvania, U.S., May 30, 2025. WEST MIFFLIN, Pennsylvania, May 30 (Reuters) – U.S. President Donald Trump on Friday lauded an 'agreement' between Nippon Steel 5401.T and U.S. Steel X.N at a political rally but stopped short of approving the companies' diplomatically sensitive merger. On a stage near Pittsburgh, Pennsylvania, decorated with signs celebrating 'American steel,' Trump declared the American steel company would remain American, while extolling its prospective new Japanese partner. 'We're here today to celebrate a blockbuster agreement that will ensure this storied American company stays an American company,' Trump told more than 1,600 people, including hard hat-wearing workers. 'You're going to stay an American company, you know that, right? But we're going to have a great partner.' Later, though, he said the deal still needed his final go-ahead, leaving unresolved whether he would allow Nippon Steel to take ownership, as they had proposed. 'I have to approve the final deal with Nippon, and we haven't seen that final deal yet,' Trump told reporters when he returned from Pennsylvania. The Japanese firm's planned acquisition of U.S. Steel, initially floated in 2023, divided the politically important state of Pennsylvania and its heavily unionized blue-collar workforce. It also introduced tension into normally friendly relations between Tokyo and Washington. Proponents of the transaction had hoped Trump's visit would end a tumultuous 18-month effort by Nippon Steel5401.T to buy the iconic American company, beset by opposition from union leadership and two national security reviews. Trump's remarks on Friday shed little light on the contours of a deal that he would approve or whether a formal green light was in the offing. He vowed to workers that U.S. Steel would be 'controlled by the USA,' no layoffs would occur, and that Nippon would invest billions of dollars to modernize U.S. steel mills to increase production. He later suggested to reporters that the company's board would be U.S.-'controlled.' The president also announced a plan, to be implemented on Wednesday, to double tariffs on imported steel to 50%, from 25%. 'I have to tell you about Nippon, they kept asking me over and I kept rejecting – no way,' Trump said, adding 'I'm going to be watching over it.' The White House and the companies have not responded to requests for comment on the status of deal talks. Trump announced the rally and appeared to endorse the merger last Friday in a social media post, sending U.S. Steel's share price up over 20% as investors bet he would soon give it the go-ahead. On Sunday, he sowed doubt, describing the deal to reporters not as the full takeover Nippon is seeking but as an investment with 'partial ownership.' U.S. Steel is headquartered near Pittsburgh, which symbolized both the erstwhile strength and more recent decline of U.S. manufacturing as the Rust Belt's steel plants and factories lost business to international rivals. Trump won closely contested Pennsylvania in 2024. 'We would not be here today without President Trump, who has secured the company's future by approving our partnership,' said Nippon Vice-Chair Takahiro Mori, who spoke before Trump. In a sign of the many open questions that remain, Japan's top trade negotiator, Ryosei Akazawa, told reporters on Friday he could not yet comment on the tie-up. 'I am aware of the various reports and posts by President Trump on social media. However, there has not yet been an official announcement from the U.S. government,' Akazawa, in Washington for tariff negotiations, said at a briefing at the Japanese Embassy in Washington. Trump technically has until Thursday to decide whether to formally approve or scuttle the deal, after the Committee on Foreign Investment in the U.S. last week completed a second review of the merger. But the timeline could slip. The road to Friday's rally has been a bumpy one. Nippon Steel offered $14.9 billion for U.S. Steel in December 2023, seeking to capitalize on an expected ramp-up in steel purchases, thanks to a bipartisan infrastructure law. But the tie-up faced headwinds from the start, with then-President Joe Biden and Trump both asserting U.S. Steel should remain American-owned as they sought to woo voters ahead of November's election. Following the previous review, Biden blocked the deal in January on national security grounds. The companies sued, arguing they did not receive a fair review process, a charge the Biden White House disputed. The steel giants saw a new opportunity in the Trump administration, which opened a fresh 45-day national security review into the proposed merger last month. But Trump's public comments, ranging from welcoming a simple 'investment' in U.S. Steel by the Japanese firm to suggesting a minority stake for Nippon Steel, did little to shore up investor confidence. Reuters reported last week that Nippon Steel floated plans to invest $14 billion in U.S. Steel's operations, including up to $4 billion in a new steel mill if the deal wins Trump's approval.

Trump says US to double tariffs on steel imports to 50%
WASHINGTON (Kyodo) -- U.S. President Donald Trump said Friday he will raise tariffs on steel imports to 50 percent from the 25 percent that his administration imposed earlier this year. Trump made the announcement during a speech at a United States Steel Corp. plant in Pennsylvania. Trump praised Nippon Steel Corp. for planning to invest $14 billion in the struggling iconic U.S. producer. Calling Nippon Steel a "great partner" for U.S. Steel, Trump said Japan is an "amazing country" and that the two steelmakers will form a "tremendous relationship." Trump's visit to the plant for a rally with steelworkers and his remarks came after he unexpectedly indicated a week ago on social media that the Japanese firm's blocked acquisition deal for the U.S. company had been cleared, referring to it as a "partnership." Nippon Steel and U.S. Steel announced their merger plan in December 2023. However, then President Joe Biden in early January this year issued an order blocking the sale of U.S. Steel to the Japanese firm, citing national security grounds, following a recommendation by a panel of federal agencies. Last month, Trump, who also opposed the sale during the 2024 presidential race, ordered the Committee on Foreign Investment in the United States to conduct another review of Nippon Steel's proposed acquisition.
