Japan’s AI story is running on two tracks tonight. On the tooling side, engineers are quietly building the scaffolds that let smaller models do real work — the AWS AIDLC workflow kit piece and a sudden 2026 wave of Excel modernization projects both make the same point: harness quality matters more than raw model size. On the adoption side, Google’s Japanese AI certificate drew over 10,000 sign-ups in a single day while public discussion keeps asking why Japan lags and how to catch up. Infrastructure plays continue underneath it — Bitkey pulled another ¥4B from a government fund, and a 700-kilometer remote robot demo pushes 60GHz wireless into real industrial use. Off to the side, US-Iran escalation just ratcheted up again. Reads like a country building, tool by tool, while the world burns at the edges.

• ハーネスエンジニアリングとループエンジニアリングの違いとは？ aws aidlc workflow kitから整理する (Zennのトレンド, In Japanese Language)
  This article breaks down the difference between harness engineering and loop engineering, organized around the AWS AIDLC workflow kit. The author explains that before adopting the kit, humans had to give AI step-by-step instructions (“find the related code,” “implement,” “build,” “fix errors”); once they used the kit, the AI would first produce a plan, investigate existing code, and run builds and tests on its own. Notably, even cheaper models get further reliably now — not because the models themselves got smarter, but because the surrounding harness changed.

• Excel/VBAとモダン開発のあいだ ─ 2026年に相次いだ XLIDE・xlflow・xlsm_devkit (Zennのトレンド, In Japanese Language)
  Compares three projects that appeared in 2026 — XLIDE, xlflow / ExStruct, and xlsm_devkit — and the design philosophies behind each. The author (who developed xlsm_devkit) digs into why the gap between Excel/VBA and modern development practice suddenly became a zone worth building in this year. The narrative is openly written from one of the developers’ perspectives.

• Googleの初心者向けAI講座を徹底レビュー　受ける価値はある？【動画あり】 (＠IT NewsInsight 最新記事一覧, In Japanese Language)
  The Japan Reskilling Consortium launched a Japanese version of the “Google AI Professional Certificate” on April 23, 2026 for people who want to learn AI but don’t know where to start. Over 10,000 people signed up in a single day. This review takes a hard look at whether the course is actually worth taking.

• 700キロ先でも成功、“60GHz帯”無線LANでつないだロボットを低遅延制御　その通信とは？ (＠IT NewsInsight 最新記事一覧, In Japanese Language)
  NTT Group, Fujitsu-affiliated 1Finity, and Mitsubishi Chemical successfully controlled an autonomous inspection robot from 700 km away using a 60 GHz-band wireless LAN for high-capacity, low-latency communication. The article walks through the technique that made it work.

• あるスタートアップの終焉： #IVS 新時代の担い手たち(１) (BRIDGE(ブリッジ), In Japanese Language)
  IVS KYOTO has become a fixture of the Kyoto summer. The author attended this year’s event both as freelance press and to support a handful of portfolio companies, and writes up the shifts they noticed on the ground — including changing signals from the next generation of founders.

• 住宅・オフィス向けプラットフォームのビットキー、政府系ファンドから40億円を追加調達 (BRIDGE(ブリッジ), In Japanese Language)
  Bitkey, which runs the “homehub” and “workhub” connect platform built around identity-based authentication and authorization alongside smart lock products, raised an additional ¥4 billion from JIC Venture Growth Investments, a government-affiliated fund. The feed summary appears truncated — the article has the full funding and round details.
