01What the data says — and does not say
This page separates the checked GeoNames row for Okayama—724,691, Asia/Tokyo, and source coordinates—from live travel claims. Those fields identify and compare the record; they do not prove current transport, accessibility, census totals, or a City Atlas Club visit.
02This city's dataset fingerprint
The source row behind Okayama is GeoNames ID 1854383. Its recorded administrative path is Okayama Shi → Okayama → Japan, and GeoNames classifies the place as a first-order administrative seat. Okayama 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 2024-12-29; that date belongs to the source record, not to every transport or visitor detail in the real destination.
Within the fixed 1,206-record atlas, Okayama ranks 765 by recorded population. Inside the 34 selected Japan entries it ranks 21; inside the 632 entries in its broad region it ranks 431. Its 724,691 population value is 0.94 times the 769,894 median for the country cohort and 0.72 times the 1,008,426 regional median. Okayama sits in the lower half of this atlas's selected Japan entries. Okayama'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.
Okayama's three nearest other atlas coordinates are Kurashiki at 16.957 km with 483,576 recorded people; Himeji at 72.469 km with 530,495 recorded people; Kobe at 114.375 km with 1,525,152 recorded people. The closest-to-farthest distance spread is 97.418 km. Compared with Kurashiki, Okayama's recorded population is 1.50 times as large. Against Okayama, Kurashiki follows Kurashiki Shi → Okayama → 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 second-order administrative seat rather than first-order administrative seat. Its recorded population is below Okayama's. Against Okayama, Himeji follows Himeji Shi → Hyogo → Japan in the source. Its point has higher latitude and higher longitude; it belongs to the same selected Japan cohort, uses the shared Asia/Tokyo identifier, and carries second-order administrative seat rather than first-order administrative seat. Its recorded population is below Okayama's. Against Okayama, Kobe follows Kobe Shi → Hyogo → Japan in the source. Its point has higher latitude and higher longitude; it belongs to the same selected Japan cohort, uses the shared Asia/Tokyo identifier, and carries the same first-order administrative seat class. Its recorded population is above Okayama's. Its nearest-neighbor distance ranks 236 of 1,206 from shortest to longest in the same snapshot. Okayama's nearest-coordinate gap falls between the tightest tenth and quarter 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 1854383, the coordinate pair 34.6500 / 133.9333, country rank 21 of 34, and neighbor GeoNames 1858311 at 16.957 km bind Okayama to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Okayama's reference point is 34.6500° north and 133.9333° east. The IANA identifier Asia/Tokyo is shared by 34 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Okayama's row carries both second- and first-order administrative labels. Okayama's point falls in the middle-latitude coordinate band used by this atlas's row checks. Okayama's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Okayama, 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.
