Method
AO.news collects the push notifications of hundreds of news apps as they are delivered, and records each one the moment it lands. This page counts the 205 notifications NHK WORLD sent from 1 Sep 2025 to 31 Aug 2026, stamped in Asia/Tokyo local time. Front-page headline robots are excluded, and the window always ends at the last complete month, so these figures update monthly rather than live. Two honest caveats: an app added mid-window shows artificially quiet early months, and a push sent only to a personalised or regional segment may not reach us. This page shows aggregates only, never the notifications themselves; the live stream is in the deck.
