nocall.ai is a generative AI voice service that takes over phone work for businesses in Japan. Operated by nocall Inc., headquartered in Shinagawa, Tokyo, it launched at the end of 2023 and has focused on making AI phone calls work reliably in real conditions, including noisy environments such as a caller standing on a train platform.
Japanese phone conversations have specific challenges, such as the natural back-channel responses and pauses that make speech feel polite and human. nocall.ai is built to handle these while meeting the high service quality Japanese enterprises expect.
The service is used across automotive, financial services, recruiting and IT. Automotive marketplace MOTA used nocall.ai to automate appraisal appointment confirmation calls and reduced same-day cancellations from about 15% to 5.7%. Raccoon Financial replaced a long-used robocall system with nocall.ai for collections and saw its rate of securing payment promises rise three to four times.
In September 2026 nocall raised about 800 million yen in a Series A co-led by JAFCO and Archetype Ventures, with existing investor Coreline Ventures participating. Cumulative funding now exceeds 1 billion yen. CEO Shogo Hayashi leads the company, which plans to invest in hiring and product development.
