Japan-filtered NSMT Octopodoidea occurrence records

Japanese National Museum of Nature and Science (NSMT) Octopodoidea occurrence records filtered to the Japan bounding box (latitude 25–50, longitude 125–150) and standardized to the common column set shared across all datamuseum Japan data sets. Unlike other sources, coordinate columns were already named Latitude and Longitude in the raw data and required no renaming. SciName is constructed from Genus, Species, and Subspecies, with trailing NA strings removed to handle records without a subspecies. This is the only source to incorporate a subspecies component in SciName. No rows were removed by the NA filter, giving the highest retention rate of all five sources at 79.9% of raw records.
