Mizuho launches conversational AI assistant "Aomaru Bank"

Mizuho Bank has developed a conversational AI assistant, “Aomaru Bank,” using OpenAI technology.

The first rollout will start in September on the Mizuho Direct app, focusing on answering customer inquiries.

The assistant uses the bank’s official mascot and is designed to understand customer needs through dialogue, not just fixed chatbot flows.

Future plans include handling procedures, asset-building consultations, and expansion to other digital channels.
