Last updated: Oct 5, 2026

Japan's Financial Services Agency has no AI-specific binding rule for banks: its position is the AI Discussion Paper, published as Version 1.0 on 4 March 2025 and updated as Version 1.1 on 3 March 2026, which keeps a technology-neutral stance (existing laws apply regardless of whether AI is used) and encourages sound adoption. The updated paper adds findings from the FSA AI Public-Private Forum (June to December 2025) on customer-facing AI and AI agents. On 22 May 2026 the FSA and the Bank of Japan jointly requested financial institutions to take nine short-term measures, over roughly one month, against the cyber threat of frontier AI. The discussion papers are non-binding and the request builds on existing cybersecurity supervision.

## Overview

The FSA's discussion paper is built on a survey of 130 firms in autumn 2024 and rejects a rules-first approach: legal regulation should be limited to areas where self-regulation cannot be expected, so principles and guidelines would be revised before any legal change. Version 1.1 records that customer-facing generative AI had begun in limited-scope deployments, groups risk mitigation for such services into four perspectives, and gives the FSA's reading of securities-sector questions on outsourcing data, access to corporate-related information and solicitation.

Frontier AI changed the agenda in 2026. After an FSA-hosted public-private meeting on 24 April 2026 and a first practitioner working group on 14 May, the FSA and the Bank of Japan issued a request on 22 May 2026 asking institutions, under direct management involvement, to prioritise critical systems, secure patching capacity, make patching risk-based and prepare for proactive shutdown of services. The request follows the national government's Project YATA-Shield package of 18 May 2026.
