Japan's SoftBank to Trial ‘Flying Base Stations' From 2026; System to Initially be Used to Support Disaster Response, Areas with Weak Signal
HAPS, which is referred to as 'base stations in the sky,' is a telecommunication platform comprised of communication devices such as antennas for mobile phone base stations, which are loaded on aircraft that fly in the stratosphere at an altitude of 20 kilometers.
SoftBank will invest about ¥2.2 billion in the U.S.-based company Sceye Inc., which develops lighter-than-air airship-type HAPS aircraft buoyed by helium and will begin using Sceye's platform. The technology will be utilized for restoring communications during large-scale disasters.
HAPS are powered by solar panels and batteries, can remain airborne for extended periods and are able to cover a wider area than ground-based base stations.
SoftBank will procure one Sceye aircraft of 65 meters long and begin test operations in Japan. The pre-commercial service will be limited to select users to accumulate operational data. Commercial services for general users are expected to begin after 2027, being used for disaster response and in areas where ground-based base station signals cannot be picked up, such as on remote islands.

Softbank to begin trial runs of ‘base stations in the sky' in 2026
Softbank Corp. said it will start trial tests of the High Altitude Platform Station (HAPS) system in Japan in 2026. (Provided by Softbank Corp.) Telecom giant Softbank Corp. announced it will begin trials of a telecommunications system that operates closer to Earth than satellites. The High Altitude Platform Station (HAPS) sends radio waves to the ground surface from an altitude of 20 kilometers. Trials of the 'base stations in the sky' are set to begin in Japan in 2026 with full-fledged telecommunications services eyed in 2027 or later. Each HAPS measures 65 meters and relies on the buoyancy of helium gas to remain airborne. The airships will be manufactured by Sceye Inc., a U.S. maker of aerospace parts. The HAPS system can deliver radio waves to a broad ground-surface area measuring 200 km across, which makes it ideal when restoring communications in times of disaster and providing network access to hard-to-reach areas such as mountainous regions. The system can also be used to communicate with drones. The HAPS vehicles are closer to the ground surface than satellites, such as those of the Starlink constellation operated by Space Exploration Technologies Corp. (SpaceX) of the United States. They can be used to provide voice calls, internet access and other services in much the same way that terrestrial networks do. HAPS services will be able to deliver radio waves within hours of a disaster occurring, Softbank officials said. 'We want to restore communications in a disaster in the three stages of immediate response by satellites, HAPS services to be made available within several hours, and finally, ground-based station services,' a Softbank official said.

Mizuho partners with SoftBank on AI to boost efficiency
Mizuho Financial Group said Friday that it has signed a strategic partnership agreement with SoftBank to introduce cutting-edge artificial intelligence to streamline operations and improve customer service. Mizuho will be the first in the financial sector to introduce "Cristal intelligence," which is being developed jointly by SoftBank and OpenAI, the U.S. developer of the ChatGPT generative AI tool. Mizuho expects the latest AI technology, which optimizes corporate tasks, to help the company increase revenue and cut costs, resulting in positive effects totaling ¥300 billion by fiscal 2030. Using the technology, Mizuho plans to analyze transaction data and market trends to quickly provide corporate customers with management advice. The financial group also expects the technology to help boost productivity in its sales activities more than twofold and reduce low-value operations by up to 50%. Mizuho and SoftBank will also conduct research and development on a large language model dedicated to the financial sector.

Japan Inc. takes global credit by storm with record sales
Debt bankers and investors are bracing for what is shaping up to be the next big trend in the global credit market: Japan Inc. raising billions abroad. A string of recent megadeals is setting the tone. A giant sale by telecom giant NTT has already driven Japanese nonfinancial corporate issuance in euros and dollars to a record this year, based on data compiled by Bloomberg. One Morgan Stanley banker in London has even come up with a nickname for such bonds: reverse Samurai. Japanese companies are heading overseas to borrow as their local market is becoming too volatile and rates are rising. They are finding there is buoyant demand for credit among dollar and euro investors in much deeper and more stable pools of capital. "We see a decent pipeline for the year ahead,' said Matteo Benedetto, EMEA co-head of investment-grade syndicate at Morgan Stanley, one of the lead banks on NTT's and Nissan Motor's sales. "While strategic projects take time, we could potentially see a growing trend of Japanese borrowers tapping the international market.' The latest trio of Japanese sales, comprising NTT, Nissan and technology group SoftBank Group, totaled more than $26 billion and drew over $128 billion in orders. NTT's deal was the second biggest of the year in the entire U.S. market. Chipmaker Kioxia sold dollar notes on Wednesday in its debut bond issuance, having upsized the deal to $2.2 billion. Behind all this is a historic shift: Japan's bond market — a vast and formerly tranquil pool of capital — is becoming unpredictable for companies looking to raise funding. Government yields, previously kept in check by the Bank of Japan, are jumping as traders are concerned about government spending ahead of a July 20 election. For example, a seven-year, single-A corporate bond denominated in yen would be expected to pay about 1.6%, according to BVAL pricing. That's double the amount recorded about 18 months ago and far above the near-zero levels back in 2021. And with higher government bond rates, the extra yield on corporate bonds is no longer the only way to earn positive returns for yen-based investors. This has the potential to dampen demand for new credit issuance in the Japanese currency. Meanwhile Japanese firms, excluding financial institutions, have ¥13.2 trillion ($89 billion) of bonds coming due by the end of 2026, which along with acquisitions could drive the need for debt issuance, according to Sharon Chen, a credit analyst at Bloomberg Intelligence. "Utilities, transportation and telecom companies have large refinancing needs and might be more likely to tap the dollar bond market to raise long-term funding,' she said. "The dollar and euro markets' depth and longer tenors could make them more attractive than the domestic market.' By contrast to the Japanese market, borrowing costs for high-grade credit in both U.S. dollar and euros have either remained stable or fallen in the past couple of years, based on data compiled by Bloomberg. And investors in the U.S. and Europe are flush with cash from relentless investor inflows and ready to put money to work. NTT's multitranche issue raised $17.7 billion — a record for an Asian corporate — after drawing orders of more than $100 billion. "There are companies that want to fund and are being a little bit opportunistic, but they wouldn't be able to do it if there wasn't demand,' said Andreas Michalitsianos, portfolio manager at JPMorgan Asset Management. "That's the thing about supply. It only comes when there's demand and syndicate desks are very good at that.' To be sure, no offering will be guaranteed success. There's the chance of investor fatigue after a flood of recent borrowing. And there are plenty of risks from unpredictable U.S. trade policy. Still, global investors have a lot of capacity to add exposure to Japan. The country's borrowers account for only about 2% of the dollar high-grade index and 1.6% of the euro benchmark. It's a similar picture in junk bond trackers. This opportunity to buy little-seen names was among the selling points of bankers when placing the NTT issue. It could be their pitch for potential future deals as well. "There is so much interest right now for U.S. dollar and euro credit, especially in the context of diversification opportunities,' said Morgan Stanley's Benedetto. NTT "was a must buy.'
