All National Parks of Japan

This group collects the 34 Protected Areas: National Park subcategory members that the atlas places in Japan, identified from each park's own sourced entity-description text, the same word-boundary country-dictionary method used for the subcategory's seven world-region groups. It sits as a second-level group nested under National Parks of Asia, one of the subcategory's seven world-region groups, giving a reader looking for a national park in Japan a direct path instead of scanning all of Asia's national parks or the whole subcategory beyond that. No country group under National Parks of Asia passes the atlas's hundred-member threshold on its own (the largest, India, holds 51 of the subcategory's Asia members), so none needs a further split at this time. Parks in every other Asian country the atlas covers at this same level sit in their own separate country group rather than here, and this group only covers national parks the atlas already places in the Asia region; a park the atlas places in a different world region sits under that region's own top-level group instead.
