reporting after careful investigation
A formal, bureaucratic term for submitting a report based on thorough examination. Rare in modern Japanese; likely encountered only in historical or official documents.
Edo-period officials submitted their findings to the shogunate as a report after careful investigation.
Compound of 勘 (intuition, investigation) and 進 (advance, submit). The exact historical derivation is uncertain; it appears to be a specialized bureaucratic term from the Edo period or earlier.
