The sustainability timetable gets real
Japan puts Prime companies on a phased sustainability clock
What changed: Japan’s plan for mandatory sustainability reporting is starting to look less like a broad policy aspiration and more like a compliance calendar.
Why it matters: Companies with an average market capitalization of ¥3 trillion or more would have to apply the SSBJ standards from the year ending March 2027. The next wave, companies averaging ¥1 trillion to under ¥3 trillion, would start in the year ending March 2028.
What to watch: Still, this is a roadmap, not the finished operating manual. The source bundle is an agenda and related briefing material for the subcommittee’s first meeting, not a final company-by-company implementation guide.

Management pressure and company read-throughs
SHIFT scraps Secure One and centralizes more of the group
What changed: SHIFT decided its cyber reorganization needs fewer layers. On May 26, the company said it was scrapping a March plan to create a wholly owned subsidiary tentatively named Secure One, which had been due to launch on June 1, and will instead have SHIFT itself absorb SHIFT SECURITY plus its subsidiaries KRAF and MAS Lab.
Why it matters: Under the earlier plan, Secure One would have been the surviving company in the merger. Under the revised scheme, SHIFT becomes the surviving company and will comprehensively inherit the contractual positions and other rights and obligations tied to SHIFT SECURITY, KRAF and MAS Lab.
DyDo’s rebound is real, Turkey accounting is still the catch
What changed: DyDo Group Holdings got back to first-quarter operating profit, but the cleaner read on the quarter is that the business recovered faster than the reported earnings line suggests.
Why it matters: The operating recovery was split between a less painful domestic drinks business and a strong overseas beverage business.
FSA wants top management in the loop on frontier AI cyber risk
What changed: Japan’s Financial Services Agency is telling financial institutions to treat frontier AI as an immediate management issue, not just a task for the security team.
Why it matters: The regulator’s concern is about time. The FSA says cyber threats are rising as AI is used in attacks, increasing their speed and scale.
Hakuhodo DY is ahead on margins, still chasing gross profit
What changed: Ahead on margin, behind on gross profit
Why it matters: Hakuhodo DY Holdings has already crossed one of the biggest hurdles in its midterm plan running through March 2027: profitability.
Japan says overseas safeguards do not replace domestic ringfencing
What changed: Japan’s latest Payment Services Act package draws a bright line for firms handling electronic payment instruments and trust-backed products: matching exposures with safe assets is not automatically the same thing as keeping returnable assets ringfenced in Japan.
Why it matters: In the domestic-holding paper, one commenter asked why an electronic payment instrument exchange service provider must include the value of users’ electronic payment instruments it manages when determining assets to be held, even though a comparable item is not required for.
