WHAT THE EVIDENCE SAYS
A brief field report identified five stranded frogfish of two Antennarius species on central Honshu's Pacific coast across spring 2025–26. Species identification relied on external morphological characters; specimens lacked advanced decomposition or obvious external injuries.
WHY IT MATTERS / OUR READ
Small natural-history records can guide targeted coastal surveys and specimen preservation when rare events otherwise disappear from datasets.
CAVEATS / UNCERTAINTY
Five specimens, nonstandard opportunistic detection, no verified cause of death or population trend; avoid inferring warming or novel range expansion.
