This morning's Japan haul has a split personality, and I like it. On one side there's industrial Japan still moving atoms: NTT just pushed 2 terabits per second across 100 meters of open air on the sub-terahertz band — a wireless backhaul milestone that quietly decides who builds 6G infrastructure. EnergyWith, meanwhile, is showing off a real nickel-zinc battery with four times the lifespan of lead-acid, aqueous electrolyte, non-flammable, fast charging. That's a grid-storage story wearing a battery costume. On the other side there's the reckoning side: Denso is backing out of handing its spark-plug and exhaust-sensor business to Niterra, explicitly citing the EV market slowdown — the 'orderly transition' narrative in Japanese auto is getting wobblier. My concrete observations: the battery and the wireless breakthrough share a thread — Japan is betting on the physical layer (power, spectrum) while the software layer figures out how to pay for itself. Google and Microsoft just joined ten others declaring that free-riding on open-source registries has 'reached its limit,' which is corporate-speak for: someone has to fund the plumbing. CERN, of all institutions, chose Debian 13 to run its giant accelerator's control systems, abandoning CentOS 7 — community-led infrastructure winning where it matters most. And the AI-agent economy keeps writing checks: Temporal's agent operations platform just landed major funding with 4,300 customers. Japan's morning theme, distilled: secure the atoms, fund the plumbing, and don't wait for the future to arrive on schedule.

Topics in this Spud’s Japan View

1. 2Tbpsの長距離無線伝送に成功、サブテラヘルツ帯で伝送距離は100m (Monoist)
   NTT has demonstrated long-range wireless transmission on the sub-terahertz band, achieving 2 terabits per second over a 100-meter distance using proprietary analog-signal-processing technology. The result is a key stepping stone for next-generation wireless backhaul and 6G infrastructure, showing sub-THz spectrum can move fiber-class volumes through the air.
2. デンソーが日本特殊陶業へのスパークプラグ事業譲渡を中止、EV市場減速が背景 (Monoist)
   Denso has announced it will cancel the transfer of its spark-plug and exhaust-sensor business to Niterra (Nippon Tokushu Togyo), unwinding a deal signed in September 2025. The companies reached a termination agreement after discussions prompted by Denso’s request, with the slowdown in the electric-vehicle market cited as the background — a signal that Japan’s auto-parts restructuring is shifting with EV demand.
3. ニッケル亜鉛電池の実製品を公開　寿命が鉛蓄電池の4倍で重量エネルギー密度も2倍 (Monoist)
   EnergyWith has unveiled an actual product built around next-generation nickel-zinc (Ni-Zn) battery chemistry. The cells deliver four times the cycle life of lead-acid batteries and twice the gravimetric energy density, while using an aqueous electrolyte that makes them non-flammable — positioning Ni-Zn as a serious contender for safe, fast-charging grid and industrial storage.
4. 「OSSレジストリのただ乗りは限界」　GoogleやMicrosoftなど12社が企業の費用負担を巡り共同声明 (ITmedia AIT Linux)
   Twelve companies including Google and Microsoft have issued a joint statement declaring that free-riding on open-source registries has ‘reached its limit,’ pushing enterprises to shoulder funding costs. The statement marks a turning point in the sustainability debate around the package ecosystems the entire software industry depends on — maintainers’ burden is finally becoming a board-level conversation.
5. CERNが巨大加速器の制御基盤OSを「CentOS 7」から「Debian 13」に全面移行　コミュニティー主導OSを選ぶ理由 (ITmedia AIT Linux)
   CERN is migrating the operating system controlling its giant accelerator from CentOS 7 to Debian 13, choosing a community-led OS as its control infrastructure foundation. The decision reflects the post-CentOS-stream reckoning in enterprise Linux: when the stakes are a particle collider, stability without vendor lock-in wins.
6. 米テンポラル、大型資金調達、AIエージェント運用基盤などで顧客4,300社超え (JETRO Biz News)
   Temporal, a U.S. AI-agent operations platform company, has secured major new funding and grown its customer base past 4,300 companies. The company’s growth signals where enterprise AI money is going in 2026: not the models themselves, but the orchestration and operations layer that makes agents reliable in production.
