Verification notes

Shutdown: This record covers the separately named AI Nana-chan conversation service and its LINE friend account, not LINE, the television series or the underlying goo AI technology. Nippon Television Network Corporation, NTT Resonant Inc. and Forecast Communications Inc. jointly provided it as a drama promotion. Their September 18, 2019 issuer announcement explicitly confirms service ended on September 17; the original product page independently says it has ended. September 18 is the dated retrospective announcement, not a claim about the earliest advance warning. The actual cutoff hour and timezone are unknown. Tokyo is a current headquarters-city proxy for cooperator Nippon Television Network Corporation, not a verified historical product-team office. AI Kahoko and AI Ie Uru Onna are separately named services, not platform variants of this product. Closure source

Launch: The operator’s September 18, 2019 retrospective explicitly dates the public service launch to August 4, 2019. This is the chatbot’s launch, not the television series premiere.
