01What the data says — and does not say
This page separates the checked GeoNames row for Hamamatsu—791,707, 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 Hamamatsu is GeoNames ID 1863289. Its recorded administrative path is Hamamatsu Shi → Shizuoka → Japan, and GeoNames classifies the place as a second-order administrative seat. Hamamatsu 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 2022-09-02; 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, Hamamatsu ranks 701 by recorded population. Inside the 34 selected Japan entries it ranks 17; inside the 632 entries in its broad region it ranks 399. Its 791,707 population value is 1.03 times the 769,894 median for the country cohort and 0.79 times the 1,008,426 regional median. Hamamatsu sits in the second quarter of this atlas's Japan population cohort. Hamamatsu'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.

Hamamatsu's nearest-coordinate gap sits in the second quarter of atlas distances. 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 1863289, the coordinate pair 34.7000 / 137.7333, country rank 17 of 34, and neighbor GeoNames 1851717 at 67.167 km bind Hamamatsu to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Hamamatsu's reference point is 34.7000° north and 137.7333° 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. Hamamatsu's row carries both second- and first-order administrative labels. Hamamatsu's point falls in the middle-latitude coordinate band used by this atlas's row checks. Hamamatsu's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Hamamatsu, 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.
