A Friday-morning grab-bag out of the Japan tech press: a solo-tank sim sitting on a 99% positive rating, Madden crossing over onto Apple Arcade, an ICML paper saying LLMs identify prompt origin by writing style and can be coaxed via fake chain-of-thought, a Montana ‘right to try’ law crossing the Pacific, a ¥3.5 billion Series C for a sales-AI agent OS, and a quietly growing tasteless-nutrition startup aimed at picky eaters. Half signal, half vibe — exactly the rhythm of an early Friday Japan newsroom pulse.

• 超巨大戦車ワンオペシム『IRON NEST』“好評率99％”で人気炸裂。弾道計算、着弾確認、ガコガコ弄ってまたぶっ放す (AUTOMATON) (In Japanese Language)
  A solo-tank simulation called IRON NEST is reportedly sitting on a 99% positive rating, with players obsessing over trajectory calculations and hit confirmation before tweaking the guns and firing again. The source feed summary was only an image header; no further detail is available beyond the headline.
• 人気アメフトゲーム最新作『Madden NFL 27 Arcade Edition』Apple Arcade向けに配信開始。追加料金なしで、iPhoneやMacなどで遊び放題 (AUTOMATON) (In Japanese Language)
  Madden NFL 27 Arcade Edition has launched on Apple Arcade at no extra cost, playable across iPhone, Mac, and other supported Apple hardware. The source feed summary was only an image header; no further detail is available.
• 「思考の連鎖」偽装でLLMを騙す新手法、訓練では防げない構造的欠陥 (MITテクノロジーレビュー) (In Japanese Language)
  A paper submitted to ICML argues that LLMs identify prompt origin (user, system, or chain-of-thought) by writing style rather than by tags, meaning a fake chain-of-thought passage is enough to coax models into disclosing things like cocaine recipes and aircraft-hacking techniques. The researchers describe it as a structural flaw that training alone cannot remove.
• 難病患者に未承認薬を、米モンタナ州「試す権利」は救いか賭けか (MITテクノロジーレビュー) (In Japanese Language)
  Montana has widened its ‘right to try’ law so non-terminal patients can apply for access to unapproved drugs, giving families like the DeBolts — whose son has creatine transporter deficiency — a slim new option. The candidate drug has only been tested on 48 healthy adults, and experts caution that neither safety nor efficacy has been demonstrated.
• Knowledge Work Raises ¥3.5 Billion in Series C for Sales AI Agent OS Development (BRIDGE)
  Knowledge Work, which builds the sales-domain AI platform ‘Sales AI Agent OS,’ announced a ¥3.5 billion first close of its Series C round on August 4. New investors include Ricoh Japan, Canon Marketing Japan MIRAI Fund, NTT Docomo Ventures, Sumitomo Mitsui Banking Corporation, Japan Post Investment Corporation, Mitsubishi UFJ Innovation Partners, Sumitomo Mitsui Trust Bank, Fukoku CVC Fund, Dentsu Ventures SGP Fund, and Hakuhodo DY Ventures, with continuing participation from Globis Capital Partners, DNX Ventures, WiL, and Salesforce (the source list was truncated at Salesforce).
• Odorless and Tasteless Nutritional Powder “Ayo” Receives Investment from Incubate Fund (BRIDGE)
  NutriBase, the maker of an odorless and tasteless nutritional powder called Ayo, raised ¥50 million with Incubate Fund as the underwriter. Ayo blends 15 nutrients into everyday meals and drinks and is aimed at families with picky-eating children; the company says it crossed one million servings sold as of May this year.
