Narrative:

Operating ZZZ-ZZZ1 did not receive notoc (notice to captain) paperwork or have apparent indication of hazmat onboard. First officer (first officer) performed main deck cargo inspection and did not report any issue. Flight operated routinely with no event. During layover post flight received email indicating hazmat was indeed loaded on aircraft. Subsequent review of flight document revealed notoc 'yes' was notated on west/B (weight and balance). Suggestions: although familiar with the west/B; the notoc yes did not standout during this instance. The lack of actual notoc paperwork did not raise a flag. In this instance the system failed. It would be helpful if possible to have notoc yes or no more prominent on west/B. There was a breakdown of communication between first officer and myself and better communication regarding checking main deck cargo would possibly have caught the error.

Title: B-747 Captain reported a communication breakdown between Captain and First Officer resulting in transporting DG cargo without required documents.

Narrative: Operating ZZZ-ZZZ1 did not receive NOTOC (Notice to Captain) paperwork or have apparent indication of HAZMAT onboard. F/O (First Officer) performed main deck cargo inspection and did not report any issue. Flight operated routinely with no event. During layover post flight received email indicating hazmat was indeed loaded on aircraft. Subsequent review of flight document revealed NOTOC 'YES' was notated on W/B (weight and balance). Suggestions: although familiar with the W/B; the NOTOC YES did not standout during this instance. The lack of actual NOTOC paperwork did not raise a flag. In this instance the system failed. It would be helpful if possible to have NOTOC YES or No more prominent on W/B. There was a breakdown of communication between F/O and myself and better communication regarding checking main deck cargo would possibly have caught the error.
