The order covers 24 critical-infrastructure operators in the power sector. The trigger was Anthropic's Claude Mythos Preview, announced April 7, which surfaced a 27-year-old bug chain in OpenBSD's TCP SACK code among others. The UK's AISI reached a more measured verdict. How Japan's penalty-free approach compares with CISA's OT principles and the EU's NIS2.
GPU-to-GPU optical interconnects were forecast to arrive around 2033. NVIDIA just pulled them in by five years, putting co-packaged optics into the NVLink switch of its 2028 Feynman generation, and locking in supply with $2 billion investments in each of Lumentum and Coherent. Furukawa Electric is spending 38 billion yen to more than quintuple DFB laser chip capacity; Sumitomo Electric supplies core components for NVIDIA's Quantum-X Photonics switches but was left out of the funding round. Where Japan's optical suppliers stand, and how NTT's IOWN runs on a different clock.

Chinese G.657.A2 optical fiber went from 32 yuan to 240 yuan per fiber-kilometer in a year, a 650% jump. The visible driver is AI data centers; the hidden one is disposable fiber-optic drones on the Ukraine front. China holds 60% of preform capacity, Japan leads on 13,824-core cables, and the US holds the hyperscaler demand.
JPX CEO Hiromi Yamaji says listing crypto ETFs on the Tokyo Stock Exchange is something the exchange can do anytime once the law and tax treatment are settled, with 2027 the earliest window.

Kioxia and Sandisk have achieved a world-first technological milestone toward 3D NAND flash memory exceeding 1,000 layers. Their multi-stacked cell array CMOS (MSA-CBA) structure with wafer-to-wafer Cu direct bonding successfully demonstrated QLC operation, and will be unveiled at the VLSI Symposium 2026 in Hawaii this June. We break down the technology, the three-way stacking race against Samsung, SK hynix, and Micron, and what soaring AI data center demand means for the NAND market.
On May 1, 2026, Epic Games Store and Fortnite finally returned to iPhone in Japan, ending nearly six years of exile. The launch follows Japan's Mobile Software Competition Act, but Epic accuses Apple of leaving 'barriers everywhere'—a 9-step install flow, a 5% Core Technology Commission, and transaction-monitoring rules that scared off third-party developers.
