Japan's Monday morning is a study in contrasts. The Linear Chuo Shinkansen — the maglev line meant to shrink Tokyo–Nagoya to forty minutes — is stuck underground in Shinagawa, its tunnel boring machine damaged and work halted for at least half a year. That's the concrete cost of building the future: even the best machines break. Meanwhile the cyber picture is grimly real: one ransomware hit on a single cloud provider cascaded into 495 companies and local governments, a reminder that Japan's digitization keeps outrunning its defenses. Meta, by contrast, is leaning in, shipping new SDKs and a proper development environment for its AI glasses — the platform race is moving from phones to faces, and Japan's developers are getting the tooling to play. On the energy front, Welion's semi-solid-state batteries push EV and ship electrification forward with safer, denser cells. And in the trenches of the post-quantum transition, a Cloudflare Workers experiment shows ML-KEM actually working in the browser's crypto API — the math of the next decade is quietly becoming deployable. Even the humble SQLite got about 4% faster; some mornings the infrastructure just works.

Topics in this Spud’s Japan View

1. Damage to Tunnel Boring Machine Halts Tokyo Maglev Work
   (News on Japan Tech)
   The Linear Chuo Shinkansen project in Tokyo's Shinagawa Ward faces at least another six months of suspension after damage was discovered in several components of the tunnel boring machine digging its underground route. The maglev line is slated to slash Tokyo–Nagoya travel time to about 40 minutes, so every delay pushes back Japan's next-generation rail flagship — and shows how punishing subterranean construction in a megacity can be.
2. Cyberattacks Spread Across Japan
   (News on Japan Tech)
   A ransomware attack on a single cloud service provider rippled across 495 companies and local governments nationwide, while a wider wave of intrusions disrupted business operations and exposed millions of customer records across Japan. The scale of the fallout from one compromised provider is a stark warning about concentration risk as Japanese firms and municipalities accelerate their cloud migration.
3. Meta、新デバイス対応のSDK最新バージョンやAIグラス向け開発環境、2D/3Dゲーム制作ツールを発表 ほか
   (Meta announces latest SDK versions for new-device support, an AI-glasses development environment, and 2D/3D game-creation tools (and more))
   (Think IT)
   Meta unveiled updated SDK versions supporting its newest devices, a dedicated development environment for its AI glasses, and new 2D/3D game creation tools. The announcement signals Meta's push to make smart glasses a first-class developer platform — the same playbook that turned smartphones into an app economy, now pointed at your face — and gives Japanese developers the tooling to build for it.
4. 気候テック10：半固体電池でEVや船の電動化を進めるウェリオン
   (Climate Tech 10: Welion advances EV and ship electrification with semi-solid-state batteries)
   (MIT Tech Review JP)
   China's Welion New Energy is developing semi-solid-state batteries that are safer and more energy-dense than conventional lithium-ion cells, targeting electric vehicles and ship electrification. Semi-solid cells sit between today's batteries and the long-promised all-solid-state breakthrough — and if Welion's approach scales, it could shorten the wait for heavier-duty electric transport.
5. 耐量子暗号ML-KEMとは？Cloudflare WorkersのWeb Cryptoで共有秘密を生成・復元してみた
   (What is post-quantum cryptography ML-KEM? Generating and restoring a shared secret with Cloudflare Workers' Web Crypto API)
   (DevelopersIO)
   Cloudflare Workers' Web Crypto API successfully generated and restored an ML-KEM-768 shared secret in a local experiment, demonstrating that the NIST-standardized post-quantum cryptography algorithm is already usable in edge runtimes. The walkthrough shows the flag-gated API working end-to-end — a practical milestone on the long road from quantum-vulnerable encryption to quantum-resistant infrastructure.
6. 「SQLite 3.54.0」リリース ─ 約4％の高速化、CLIとクエリープランナーを改善
   (SQLite 3.54.0 released — roughly 4% faster, with CLI and query-planner improvements)
   (Think IT)
   SQLite 3.54.0 delivers roughly 4% faster performance, with improvements to the command-line interface and the query planner, plus a new disk-usage check feature. The release also ends support for Windows versions before XP — a notable cutoff for the world's most widely deployed database engine, which quietly underpins nearly every app you own.
