FDI is the missing piece of Japan’s puzzle

Noahpinion • 7058 implied HN points • 17 Dec 25
💼 Business Manufacturing
  1. Japan should focus on attracting greenfield FDI — foreign firms building new factories and research centers — because these projects bring fresh investment, local jobs, and direct technology transfer.
  2. Increasing exports is crucial to strengthen the yen and offset a shrinking domestic market, and greenfield platform FDI is an effective way to create export-oriented production and accelerate learning-by-exporting.
  3. Japan already has strong selling points for investors (a weak yen, skilled suppliers, national security/‘friendshoring’ appeal, efficient permitting, and global desire to live there), so policy should target and scale greenfield platform FDI across multiple high-value industries beyond semiconductors.

Chinese Peptides

ChinaTalk • 607 implied HN points • 20 Feb 26
🔬 Science Manufacturing
  1. Chinese factories and online sellers are mass-producing and exporting a wide range of peptides — from approved drugs to experimental research chemicals — at far lower prices than brand-name medicines. They advertise on social apps and ship directly to foreign customers with fast turnaround and bulk incentives.
  2. Many popular peptides lack robust human trials and can contain hard-to-detect impurities, so injectable dosing and sterility carry real health risks. Regulatory enforcement is murky: sellers use “research use only” labels to dodge oversight and FDA actions have varied with political leadership.
  3. Demand is driven by biohackers, athletes, and people chasing weight loss or faster healing, and injections have become socially normalized after drugs like Ozempic. That demand meets China’s large-scale peptide manufacturing capacity, creating a booming gray market that outpaces formal clinical research.

The only thing worse than sweatshops is no sweatshops
