Source identity and administrative path
The source row behind Ōta is GeoNames ID 8469289. Its recorded administrative path is Ota-ku → Tokyo → Japan, and GeoNames classifies the place as a second-order administrative seat. Ōta occurs once as a primary city label in this atlas sample; the numeric ID remains the durable source key if names change. The city row itself was updated 2025-06-02; that date belongs to the source record, not to every transport or visitor detail in the real destination.
Population position inside fixed cohorts
Within the fixed 1,206-record atlas, Ōta ranks 734 by recorded population. Inside the 34 selected Japan entries it ranks 18; inside the 632 entries in its broad region it ranks 416. Its 748,081 population value is 0.97 times the 769,894 median for the country cohort and 0.74 times the 1,008,426 regional median. Ōta sits in the lower half of this atlas's selected Japan entries. Ōta's recorded value stays within one quarter of the country-cohort median used here. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Nearest-reference pattern
Ōta's three nearest other atlas coordinates are Kawasaki at 4.527 km with 1,538,262 recorded people; Tokyo at 14.428 km with 9,733,276 recorded people; Yokohama at 15.431 km with 3,777,491 recorded people. The closest-to-farthest distance spread is 10.904 km. Compared with Kawasaki, Ōta's recorded population is 0.49 times as large. Against Ōta, Kawasaki follows Kawasaki-shi → Kanagawa → Japan in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Japan cohort, uses the shared Asia/Tokyo identifier, and carries the same second-order administrative seat class. Its recorded population is above Ōta's. Against Ōta, Tokyo follows Tokyo → Japan in the source. Its point has higher latitude and lower longitude; it belongs to the same selected Japan cohort, uses the shared Asia/Tokyo identifier, and carries capital of a political entity rather than second-order administrative seat. Its recorded population is above Ōta's. Against Ōta, Yokohama follows Yokohama Shi → Kanagawa → Japan in the source. Its point has lower latitude and lower longitude; it belongs to the same selected Japan cohort, uses the shared Asia/Tokyo identifier, and carries first-order administrative seat rather than second-order administrative seat. Its recorded population is above Ōta's. Its nearest-neighbor distance ranks 38 of 1,206 from shortest to longest in the same snapshot. Ōta's nearest-coordinate gap belongs to the tightest tenth of the atlas. This pattern can reveal whether other catalog references are geographically close, but it cannot establish whether a border crossing is possible or practical, or whether rail, road, fare, or journey-time connections exist. Read as one record signature, GeoNames 8469289, the coordinate pair 35.5613 / 139.7161, country rank 18 of 34, and neighbor GeoNames 1859642 at 4.527 km bind Ōta to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Coordinate, time-zone and class cohorts
Ōta's reference point is 35.5613° north and 139.7161° east. The IANA identifier Asia/Tokyo is shared by 34 city rows in this catalog, while the GeoNames class PPLA2 is shared by 341 rows. Ōta's row carries both second- and first-order administrative labels. Ōta's point falls in the middle-latitude coordinate band used by this atlas's row checks. Ōta's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Ōta, so the profile preserves that missing value instead of guessing terrain. Together these fields form a reproducible identity check for this page, not a claim about walkability, climate or accessibility.
