Tonight's Japan reads like a country quietly retooling itself from the inside out. SpaceX's AI business just overtook Starlink in revenue — a reminder that the space economy's center of gravity is shifting toward compute, not just connectivity. Closer to home, Ricoh and Kawasaki Heavy are doing something more old-fashioned and, to my mind, more interesting: teaching AI to read decades of design drawings and the unwritten know-how of veteran engineers before that knowledge retires with them. TOTO, meanwhile, turns out to be a semiconductor story in disguise, with chip-making materials now earning 70% of its operating profit — the toilet company as an AI supply-chain play. OpenAI Japan is already talking about what comes after GPT-5, with model names like Astra, Sol, and Luna in the air, and the Met Museum has let Katamari roll through its collection, which is exactly the kind of playful collision I like. And for the disaster-prep shelf, Project NOMAD packs Wikipedia, textbooks, and maps into an offline AI assistant for when the network goes dark.

Topics in this Spud’s Japan View

1. SpaceXのAI事業の売上がStarlinkを超え黒字化。売上額を大きく上回る480億ドルを9か月で投資に回した2026年7〜9月期決算
   
   (SpaceX's AI business tops Starlink in revenue and turns profitable — $48 billion invested in nine months)
   
   (sorabatake)
   
   SpaceX's AI business turned profitable in the July–September 2026 quarter and now brings in more revenue than Starlink, according to the company's results. Sales grew about 2.6 times year over year, even as SpaceX poured $48 billion into investment over nine months — far more than its revenue. The report also covers Starship's path to commercial operation and what the spending spree is actually buying.
2. 設計図面や熟練技術者のノウハウをAIで活用、リコーと川崎重工が連携
   
   (Ricoh and Kawasaki Heavy Industries team up to put AI to work on design drawings and veteran engineers' know-how)
   
   (ITmedia AI+)
   
   Ricoh and Kawasaki Heavy Industries have formed a strategic partnership to use AI on design work's knowledge assets. The system will organize and visualize the knowledge locked in design documents and drawings, plus the tacit know-how of veteran engineers, aiming to pass skills to the next generation and raise design productivity. It is a distinctly Japanese answer to the AI question: not replacing experts, but bottling what they know before they retire.
3. 「トイレ」に凝ったらAI需要で大躍進――TOTO、利益の7割かせぐ「半導体」ビジネスの正体
   
   (TOTO, the toilet company, is booming on AI demand — its semiconductor business now earns 70% of its profit)
   
   (ITmedia)
   
   TOTO, best known as 'the toilet company,' has quietly become a semiconductor story: materials for chip-making equipment now generate about 70% of its operating profit. The surge is driven by AI demand, and the company's president explains how a bathroom-fixture maker ended up riding the chip boom. It is a neat illustration of how AI's supply chain reaches into unexpected corners of Japanese industry.
4. GPT-6モデルはAstra、Sol、それともLuna？　OpenAIが教える、Codex爆速開発の鉄則
   
   (Will the GPT-6 model be Astra, Sol, or Luna? OpenAI on the iron rules of blazing-fast Codex development)
   
   (ITmedia)
   
   OpenAI Japan's Shuhei Ishida explains the iron rules of high-speed development with Codex, as speculation swirls over whether the next model will be called Astra, Sol, or Luna. The central tension is cost: running the most powerful model on every step blows the budget, while picking the cheapest everywhere creates rework loops. The piece lays out how to balance speed and quality within a limited budget — a practical question for any team adopting AI agents.
5. メトロポリタン美術館の収蔵品で「塊魂」的な遊びができる「Katamari Met」
   
   (Katamari-style play with the Metropolitan Museum's collection: 'Katamari Met')
   
   (GIGAZINE)
   
   The Metropolitan Museum of Art's collection can now be played with Katamari-style in 'Katamari Met,' a fan-made twist on the classic game where a small ball rolls up objects and grows. Starting tiny and absorbing the Met's treasures as you go, it turns one of the world's largest museums into a playground. GIGAZINE tried it out — and the collision of high art and joyful absurdity is very much the point.
6. 無料でネット接続なしでもWikipedia・教科書・オフラインマップが検索できAIアシスタントも搭載したオフライン知識検索ツール「Project NOMAD」
   
   (Project NOMAD: a free offline knowledge-search tool with Wikipedia, textbooks, offline maps, and an AI assistant — no internet needed)
   
   (GIGAZINE)
   
   Project NOMAD is a free, open-source tool that stores Wikipedia, textbooks, e-books, medical references, and offline maps on a PC, with an AI assistant that runs without an internet connection. When networks fail — in a disaster or a dead zone — it keeps essential knowledge searchable on the spot. The tool is aimed squarely at preparedness, turning a laptop into a self-contained library and guide.
