Translation guide
A trapdoor is a door in a floor, ceiling, or roof, often hidden or used for access. In Japanese, the most common word is 床下収納 for floor storage, but other terms exist for stage trapdoors, ceiling hatches, and figurative traps.
A door set into a floor, often leading to a basement, crawlspace, or storage area.
Literally 'under-floor storage'. This is the standard term for a trapdoor that opens to a storage space beneath the floor, commonly found in Japanese homes.

Means 'under-floor inspection opening'. Used for access hatches to crawlspaces for maintenance, not necessarily for storage.
床下点検口から配管をチェックした。
I checked the pipes through the under-floor inspection hatch.
The English loanword 'trapdoor' is possible but not common for home contexts. It may be understood, but 床下収納 is preferred.
