This assessment is based on seal analysis from the submitted photo. We recommend provenance review and, when possible,
physical inspection by an expert.

Explainable AI reasoning
The seal border continuity and stroke density align strongly with authenticated reference clusters. The internal
stroke topology shows consistent negative-space structure typical of Edo-period carving styles. Ink diffusion and
paper texture cues are consistent with aged materials, within the limitations of a single photo.
Seal match: strong
Forgery risk: low
Confidence: medium-high
Recommended next steps
- Provide a close-up photo of the seal area (straight angle, high resolution).
- Share provenance documentation (receipts, prior appraisals, catalog entries).
- If high value: request expert physical inspection and material analysis.
Limitations
- Photo compression / blur can reduce confidence.
- Partial seals may reduce match reliability.
- AI results are probabilistic and should support—not replace—expert judgment.
