Japan's privacy watchdog issues administrative guidance to KDDI over leak of 12.23 million people's data
The Personal Information Protection Commission announced on the 19th that it has issued administrative guidance to KDDI over unauthorized access to the company's email system that leaked personal information on approximately 12.23 million people. The commission pointed out that KDDI failed to take measures to limit the spread of damage from the unauthorized access, and demanded a report on any secondary damage and on measures to prevent recurrence. It also issued administrative guidance to businesses that used the email system, citing inadequate management practices such as storing personal information without encryption, and called for improvements. According to the commission, multiple businesses were hit by unauthorized access in June, resulting in the leak of personal information on about 12.23 million people, but no secondary damage from the leak has been confirmed.
Oasis says it will not support buyout offer below 3,640 yen per share for Kakaku.com
Hong Kong fund Oasis Management said on the 19th that among multiple buyout proposals for Kakaku.com, in which it holds about 19.5% of shares, the tender offer of up to 3,640 yen per share currently proposed by the LINE Yahoo consortium is the best option for minority shareholders. It also said that as long as the price of the rival tender offer by European investment firm EQT, at 3,570 yen, is below the LINE Yahoo camp's offer, it has no intention of tendering its shares to EQT. Kakaku.com has expressed support for EQT's buyout proposal, and on the 13th the price was raised from 3,450 yen to 3,570 yen per share. LINE Yahoo, teaming up with US investment fund Bain Capital, set the purchase price at 3,520 yen per share if it launches a tender offer for Kakaku.com, and at 3,640 yen if it signs an agreement under which major shareholder KDDI will not tender. LINE Yahoo has made Kakaku.com's expression of support a condition for launching the tender offer. KDDI has already signed a non-tender agreement with EQT, and can tender to a rival offer only if that rival offer is launched at a price more than 2% above EQT's tender offer price. For this reason, Kakaku.com regards the 3,640 yen price as unfeasible, but Oasis said that if EQT's tender offer fails, the main obligations under the existing contract would lapse, making a tender offer at 3,640 yen feasible. It also called on Kakaku.com to take steps such as withdrawing its support for EQT's proposal.
KDDI to end roaming provision to Rakuten at the end of September
KDDI President Hiroji Matsuda revealed on the 7th a policy to terminate the current contract for providing mobile network roaming to Rakuten Mobile at the end of September. From October onward, provision in urban areas will be discontinued, while it will continue for a certain period only in some rural areas where Rakuten's base station deployment is lagging. This is to focus on improving communication quality for its own brand users, and President Matsuda stated, "The network is experiencing more congestion than expected. Ending the contract will resolve this." KDDI has been providing roaming to Rakuten since October 2019, but due to delays in Rakuten's 5G base station deployment, the termination of provision may lead to a decline in communication quality.
Nokia Insiders Buy Shares as Nvidia Partnership Fuels AI Network Ambitions
Nokia insiders have been quietly accumulating shares, signaling confidence in the company's AI-driven network strategy backed by a $1 billion investment from Nvidia. In late May, Victoria Hanrahan, chief of staff to the CEO, bought 44,682 shares on the NYSE at an average price of about $15.81 per share, a purchase worth just over $700,000.

The buying spree follows Nokia's October 2025 strategic partnership with Nvidia to pioneer an AI platform for 6G, which includes Nvidia's $1 billion equity investment at $6.01 per share and plans to integrate Nvidia GPUs into Nokia's base stations. T-Mobile US has agreed to trial Nokia's AI RAN designs starting in 2026, and Nokia is building an AI RAN center in Dallas with partners like KDDI and SoftBank to develop AI-powered radio networks.

According to the three companies, this is the first initiative in Japan to simultaneously advance the conservation of endangered species and support for artists with disabilities using blockchain technology.

Soracom cuts SG&A ratio by 6 points with generative AI, leveraging field data and telecom tech for competitive edge
Ken Tamagawa, President and CEO of Soracom, which operates an IoT platform, announced at the annual event SORACOM Discovery 2026 that the company reduced its selling, general and administrative expense ratio against revenue by 6 percentage points in one year through the use of generative AI. After declaring internally that it would become a post-AI organization, the company restructured into small teams for each business combined with AI, resulting in generative AI writing nearly 100 percent of source code and cutting SG&A costs without reducing headcount. Tamagawa noted that as AI foundation models become commoditized, competitive advantage lies in accumulating company-specific field data and token capital, the ability to master AI. Leveraging its strength in developing telecom as cloud-based software in-house, Soracom holds the gateway for feeding field data into AI. The newly announced AI agent service, SORACOM Agent, provides conversational support from IoT planning to operations and accumulates business knowledge as long-term memory. The company also jointly developed an IoT SIM with KDDI supporting the new eSIM standard SGP.32 for remote SIM rewriting, and began commercial provision. Furthermore, it announced a business selling core network software to telecom operators, with commercial use already underway through a joint venture with the Marubeni I-DIGIO Group.
Verizon Partners With KDDI to Provide 5G Connectivity for New BMW Vehicles in the U.S.
Verizon Communications has partnered with KDDI Corporation to provide 5G Standalone and LTE connectivity for newly manufactured BMW Group vehicles in the United States.

NTT Docomo, KDDI, SoftBank and two other mobile carriers announced on the 8th that they are postponing the introduction of phone numbers starting with 060.
