Japan to Lead Charge on International Rules for Space Debris Removal; U.K., N.Z., Developing Countries Eyed as Partners
A satellite operated by Astroscale Holdings Inc. captures an image of space debris created by a rocket launch.
GENEVA — With the aim of creating international rules for space debris removal, the government is set to form a group of like-minded countries to discuss related challenges.
Japan aims to take the initiative in establishing the rules by leveraging its technological advantage in the field. Its goal is ensuring the security of outer space and expanding the space business market.
Minoru Kiuchi, state minister for science and technology policy who is in charge of space policies, will reveal the plan at a U.N. meeting to be held in Vienna on Wednesday.
Along with defunct satellites, debris is also generated by rocket launches. Such debris orbits the Earth at extremely high speeds, and the amount is rapidly increasing amid a surge in space development. According to NASA, there are currently more than 20,000 pieces of debris, both small and large.
The United Nations Committee on the Peaceful Uses of Outer Space compiled guidelines in 2007 due to the risk of collision between operational satellites or the International Space Station and space debris. The guidelines ask countries to design probes and satellites which do not generate space debris when launched.
However, the guidelines are not legally binding, so any response by a country is voluntary. There are also no rules for the removal of existing space debris, raising concerns among companies seeking to enter the space business.
In Japan, Astroscale Holdings Inc., a Tokyo-based startup, has been developing its own space debris capture technology where tools such as robotic arms on a satellite capture debris and drop it into the atmosphere where it burns up before reaching the surface. The company is a global leader in the field.
The government has decided to take on establishing international rules with countries that share a common understanding of the importance of space debris removal. It plans to discuss legal issues such as the removal of space debris generated by other countries, envisioning the results to be incorporated into future U.N. guidelines.
The government expects the United Kingdom and New Zealand, countries which share an understanding on developing international rules with Japan, as well as developing countries seeking to enter the space business, will be founder members of the group.
Japan aims to take the initiative in establishing international rules as soon as possible, as space debris removal technology could potentially be utilized by a country to neutralize another's satellites. It also seeks to establish order in space to head off China, which aims to become the space power.

The real nuclear moonshot is here on Earth
In America in 2025 it's tough to know which we will see first, the Epstein files or a nuclear power plant on the moon. The Trump administration certainly seems more committed to the latter. Transportation Secretary and acting head of NASA Sean Duffy wants a lunar-ready reactor by 2030. This is certainly one way of pushing more federal funding toward advanced reactor research. It also magnifies, through a fantastical lens, the broader hype around new nuclear power — and the daunting challenge of getting it deployed to meet our more immediate needs for carbon-free power back here at home. Developing extraterrestrial nuclear power is a worthy research project. If we are to someday establish permanent settlements on the moon, they will require a lot of energy for melting ice, growing food, mining crypto and whatnot. Nuclear power offers the benefit of requiring relatively little fuel for high output and, unlike solar power, could keep running through the roughly two-weeklong lunar night. NASA already has an ongoing effort to develop a 40 kilowatt reactor design, the Fission Surface Power project. A typical nuclear plant is one gigawatt, or 25,000 times that, and even so-called small modular reactor, or SMR, designs usually aim for tens of megawatts. Duffy is aiming for a 100 kilowatt unit. The U.S. has certainly designed nuclear reactors for demanding environments before, like beneath the Greenland ice cap or inside submarines sailing the ocean depths. But developing one that can operate safely in the face of the moon's ultraextreme temperatures, low gravity and exposure to solar radiation, to cite a few wrinkles, is far beyond that. It would also have to be carried almost a quarter-of-a-million miles through space and deposited gently on the lunar surface. The transport cost alone would be literally astronomical. NASA has previously targeted a reactor weight of under six metric tons. Even assuming that could be met, before taking into account the cost of designing and building the thing, shipping it skyward could cost $7 billion alone — or, on a per kilowatt basis, roughly 6,000 times the estimated cost of building a regular nuclear plant on Earth. Putting dollars towards this when ordinary household power bills are taking off possibly doesn't present the best optics. Conceivably, Space Exploration Technologies, or SpaceX, might eventually cut that shipping cost dramatically. But this rather assumes we are all happy putting fissile material on rockets that have sometimes spontaneously disassembled in spectacular fashion as well as U.S. President Donald Trump allowing such a contract to go to one of Elon Musk's companies in the first place. You don't go to the moon to save money, though. The bigger problem here is the five-year goal. True, the U.S. crushed that 1960s end-of-decade space deadline. But the U.S. nuclear power industry's track record is less inspiring. One of the main pitches for SMRs is that they offer a solution to the time and cost overruns that have plagued conventional plants. As of today, however, only one developer, NuScale Power, has received approval from the Nuclear Regulatory Commission for its reactor, and there are no commercial reactors under construction. Trump has signed several executive orders to reinvigorate the U.S. nuclear sector by streamlining approvals and directing national laboratories and the military to pitch in, calling for 10 gigawatts of new capacity to get under way by the end of this decade. Strategic considerations mean the ambition is laudable enough and there are signs of growing interest in nuclear power, from Silicon Valley's hyperscalers to New York's governor. But interest does not a nuclear renaissance make — and certainly not one that delivers at scale this side of 2030. The inherent risks and higher costs involved in first-of-a-kind deployments of new nuclear capacity mean potential customers would rather see someone else take the plunge first. Even the hyperscalers, with their deep pockets and power-hungry AI ambitions, remain long on intent and short on binding commitments. There is much government push but less in the way of market pull, as Bloomberg NEF's Chris Gadomski summed up in a recent report. Yet you wouldn't know that from looking at the stocks of SMR startups, which have launched early. Duffy's lunar ambitions will no doubt add to the enthusiasm. But for the SMR darlings, delivering on such high-priced expectations, just for here on plain old planet Earth, is a moonshot already. Liam Denning is a Bloomberg Opinion columnist covering energy.

Japan's Nikkei 225 breaches 43,000 for first time ever
Tokyo stocks rose to a record high for a second consecutive day as inflation figures released overnight suggested that interest rates could soon fall in the United States and on positive tariff-related news. After hitting 42,999.71 intraday on Tuesday , the Nikkei 225 stock index breached the 43,000 level for the first time ever on Wednesday and continued higher from the open with some conviction. The benchmark ended the day up 1.30%, at 43,274.67. "If the market continues in this fashion, it does appear that 45,000 is the next target that you're going to be facing,' said Takeo Kamai, head of execution services at CLSA Japan. Shares in Toyota Motor, Japan's largest company by market capitalization, rose 0.7% on Wednesday and is up about 6.4% over the past week. Sony Group shares rose 3.46% while Recruit Holdings gained 5.10%. Mitsubishi Heavy Industries shares were up 3.79% and are trading at all-time highs. Its share price has more than doubled over the past year and has risen 14-fold over the past five years. The yen was steady on Wednesday, strengthening slightly to about ¥147.8 to the dollar. Tuesday's strong performance in Tokyo — with the Nikkei 225 ending the day up 2.15%, at 42,718.17 — was in part triggered by a 90-day trade-war truce between the U.S. and China, Kamai said. On Monday in Washington and Tuesday morning in Beijing, the White House and China's Commerce Ministry issued a statement extending the suspension of higher-rate tariffs on each other for another 90 days to allow for further negotiations. 'I think that was enough to trigger the Nikkei to break new record highs,' Kamai said. 'And then once you break the new record highs, and you see short covering, you see retail buying leveraged ETFs, and then the momentum just builds up to the upside.' On Tuesday, the United States reported that inflation remained steady in July and below expectations, raising hope that tariffs will have a limited effect on prices and allow the U.S. Federal Reserve to start lowering interest rates. Inflation in the United States was 2.7% in July, the Bureau of Labor Statistics reported, lower than the 2.8% forecast by analysts and the same as the June figure. In overnight trading, the Nasdaq Composite index and the S&P 500 index both closed at record highs following the release of the inflation data. A trade deal reached between Japan and the United States on July 22, and subsequent clarifications of the terms of that deal, have also continued to support stocks, Kamai said. 'There's a little bit more, I guess, belief that the rally can continue,' he added. Risks still exist given that trade relations between Japan and the U.S. remain 'murky,' he noted, adding that the market tends to overlook underlying risks these days. The two countries remain at odds over the exact meaning of Japan's $550 billion investment pledge included in the trade agreement, while a drop in auto tariffs has been promised by the United States but not yet implemented. 'The headline risks are definitely out there, so any kind of negative headlines will probably see a quick turnaround in terms of profit taking,' Kamai said.

Man Group's Japan fund buying bank stocks in bet on inflation
An investment manager at the world's largest publicly traded hedge fund, Man Group, is adding Japan's financial shares to her portfolio on the view the nation's central bank will need to hike interest rates to tame inflation. The relative stability in the yen also provides room for the Bank of Japan to act, according to Emily Badger, a co-manager of the Man Japan CoreAlpha Fund, which has £2.45 billion ($3.3 billion) of assets and outperformed 93% of its peers over the past three years, according to compiled data. "Inflation is higher than last year, the yen-dollar is more stable than last summer,' said the U.K.-based portfolio manager. "We have therefore taken the opportunity in the short term to increase our position in the bank sector slightly, as we think the path is clearly towards normalization.' While buying may be slight, the shift for the long-only fund is notable given that it was underweight Japan's financial sector at the start of the year. And back in late 2023, when investors were split on the fate of bank stocks ahead the BOJ ending negative interest rates, Badger was among those who viewed the benefits of future tightening as already priced in. BOJ Gov. Kazuo Ueda last month rebutted claims the central bank was behind the curve in raising interest rates, which tempered expectations of near-term hikes. Although the BOJ raised inflation forecasts at its last meeting that concluded on July 31, investors viewed the overall stance as dovish. Overnight index swaps now suggest a 55% chance for a hike by the end of the year, down from 79% before the July BOJ decision. Swaps had suggested 100% before U.S. President Donald Trump's barrage of "liberation day' tariff threats in early April. "Once the trade situation and the political uncertainty die down, the policy rate will be pushed towards 1%,' said Badger. Badger describes the increase in her fund's bank holdings as "very gradual,' adding that her larger positions remain in the auto sector and factory automation, where she anticipates a rally once there's more clarity on the U.S.-Japan trade deal. She is hopeful further corporate governance improvements will boost Japanese stocks, which struck record highs this month but still lag their regional peers year to date. She said the next phase of corporate governance reforms will involve enhancement of longer-term profitability and growth. "Because of that we think that long term Japanese equities remain an opportunity,' she said.
