Temminck, in his original description, noted that the crab was known to the Japanese for the serious injuries it can cause with its strong claws. The Japanese spider crab is "occasionally collected for food,"and even considered a delicacy in many parts of Japan and other areas in the region. A total of {{convert|24.7|t|lb}} were collected in 1976, but only {{convert|3.2|t|lb}} in 1985The [[crab fisheries|fishery]] is centred on [[Suruga Bay]] and they are caught using small trawling nets. The population has decreased in number, forcing fishermen into exploring deeper waters to catch them. Harvesting of the crab is forbidden during the spring, when crabs move to shallower water to reproduce. Populations of this species of crab have diminished over recent years and there are many efforts to protect them. The average size caught by fishermen is a leg span of {{convert|1.0|-|1.2|m|abbr=on}}.
