NTT's IOWN (Innovative Optical and Wireless Network) all-photonics network reached 50% deployment in Tokyo and Osaka metro areas by June 2026. Key specs: 1/200th the power consumption of traditional electronic switching, 125x capacity, <1ms latency between Tokyo-Osaka. Commercial applications: (1) remote surgery - surgeons at Keio University Hospital operated on Kyoto patients with <2ms round-trip latency (2) financial - HFT firms using photonics for Tokyo-Osaka arbitrage (3) data center - NTT's photonics-based data centers reduce cooling costs by 60%. Global telcos (AT&T, Deutsche Telekom) are licensing IOWN technology. Challenge: last-mile fiber upgrades are expensive ($50-100B nationally). Within Japan, IOWN positions NTT as infrastructure leader for the AI era. Outside Japan, export depends on geopolitical alignment.
