| Risk-Weighted Assets (Billions of Yen) | 68,664.5 | 3,934.1 | 64,730.4 |

Material Changes Versus Prior Period
Compared to the March 31, 2022 quarter-end, the consolidated group experienced a decline in all major capital ratios. The Total Capital Ratio decreased by 1.30 percentage points, and the CET1 Ratio decreased by 0.70 percentage points. This decline was driven primarily by a significant increase in Risk-Weighted Assets (RWA), which rose by approximately 3.9 trillion yen (6.1% increase). While Tier 1 Capital and CET1 Capital saw slight absolute increases (6.1 billion yen and 12.9 billion yen respectively), the growth in RWA outpaced capital accumulation, resulting in lower ratios.
Guidance, Outlook, and Risks
The filing text does not provide management commentary, future guidance, or specific risk factors beyond the disclosure of capital adequacy metrics. The document serves strictly as a regulatory announcement of the June 30, 2022 capital position.
Investor Verification Checklist
- Verify the drivers behind the 3.9 trillion yen increase in Risk-Weighted Assets to determine if it stems from loan growth or changes in risk weighting.
- Confirm that the decline in capital ratios remains well above regulatory minimum requirements and internal targets.
- Review the full quarterly earnings release for revenue and profit data, as this Form 6-K contains only capital ratio information.
- Assess the impact of the capital ratio decline on the company's ability to pay dividends or conduct share buybacks.
