Monday evening in Japan's tech world kept one eye on the sky and the other on the inbox. Rakuten and AST SpaceMobile agreed to build a domestic network that lets ordinary smartphones talk straight to low-orbit satellites, no dish required — the kind of infrastructure that makes 'no signal' a rarer excuse. Closer to the ground, the scams got physical: police arrested a man in Ginza for running a fake base station on the street to push fraud SMS, while docomo confirmed customer data leaked from its online shop and My docomo app. SpaceX, meanwhile, is aiming to catch its Starship itself on the November 14 test flight, and on the factory floor Mazda posted record first-half sales while a small eyewear brand showed that 3D printing can fit glasses to a face the way a tailor fits a suit.

Topics in this Spud’s Japan View

1. スマホと衛星の直接通信、国内インフラ整備へ　楽天とASTが新会社設立で合意
   (Direct smartphone-to-satellite communication heads for domestic infrastructure: Rakuten and AST agree to found a new company)
   (sorae)
   Rakuten Group and AST SpaceMobile agreed on November 9 to establish a new joint company, Rakuten AST, to build a domestic communications network in which low-orbit satellites connect directly with ordinary smartphones. The venture aims to bring satellite-to-phone service into Japan's infrastructure, extending coverage to places terrestrial networks struggle to reach — mountains, remote islands, and disaster zones — without any special handset hardware.
2. 偽基地局を使った詐欺SMSの送信についてまとめてみた
   (Fake base stations used to send scam SMS — a roundup)
   (piyolog)
   Tokyo's Metropolitan Police Department announced on November 9 that it had arrested a 31-year-old man in Ginza on suspicion of operating a fake base station from a street in the shopping district. The man, a Chinese national living in Kita-ku, allegedly ran the rogue station on the afternoon of November 7 to send fraudulent SMS messages, impersonating legitimate senders to lure victims — a reminder that the most convincing phishing can come from hardware on the sidewalk, not just the internet.
3. ドコモオンラインショップとMy docomoへの不正アクセスについてまとめてみた
   (Unauthorized access to the docomo Online Shop and My docomo — a roundup)
   (piyolog)
   NTT docomo confirmed on November 5 that customer information leaked after unauthorized access to its docomo Online Shop and My docomo services. An alert on the morning of November 4 triggered a response that shut the services down, briefly restored them, and then halted them again as the investigation continued. The incident lands days after the MUJI breach widened, making November a rough month for Japanese consumer data.
4. スペースXが「スターシップ」第15回飛行試験を日本時間11月14日にも実施予定　初の宇宙船キャッチへ
   (SpaceX plans Starship's 15th flight test as early as November 14 Japan time, aiming for the first catch of the ship itself)
   (sorae)
   SpaceX announced on November 7 that it is preparing Starship's 15th flight test for as early as November 14 Japan time, with a first: the company will attempt to catch the Starship upper stage itself, not just the Super Heavy booster. The test is the next step for the vehicle NASA plans to use for lunar landings, and each successful catch brings reusable super-heavy lift a little closer to routine.
5. マツダが2026年度上期売上高で過去最高、下期もコスト削減で通期見通し必達へ
   (Mazda posts record first-half revenue for fiscal 2026, vows cost cuts to hit its full-year outlook)
   (Monoist)
   Mazda reported record first-half revenue for fiscal 2026, the highest in the company's history, when it presented its second-quarter results and full-year outlook. The automaker said it will lean on cost reductions in the second half to deliver on its full-year forecast, a disciplined message in a year when Japan's carmakers are juggling tariffs, electrification costs, and a shifting domestic market.
6. 眼鏡も洋服のようにサイズを選ぶ、3Dプリントで多サイズ展開を実現
   (Choose glasses like clothes by size: 3D printing enables a multi-size lineup)
   (Monoist)
   Glass Factory is expanding its 3D-printed eyewear brand GLAFU with a new collection that treats glasses like clothing: three front sizes and four temple sizes, so wearers can choose a fit for the shape of their face. The company reworked its manufacturing process and materials and added spring hinges for comfort, betting that made-to-measure frames — printed, not bent — can move eyewear from one-size-fits-most to genuinely personal.
