Okayama Momotaro Airport is a low-elevation field at 806 ft (246 m), positioned at 34.7569° N, 133.8550° E in the Northern subtropics. The runway snapshot lists 1 runway and a longest runway of 9,843 ft / 3,000 m. The airport clock uses Asia/Tokyo (JST, UTC+09:00), so cross-date arrivals should be checked against this zone rather than the airline origin city.
Sōja is the closest retained city-time anchor at 13 km. HIJ Hiroshima is the closest retained airport alternative at 93 km.
OKJ is compared with HIJ Hiroshima at 93 km, TKS Tokushima at 98 km, UKB Kobe at 126 km, KIX Osaka at 132 km, ITM Osaka at 145 km inside the retained Japan airport set, which is useful when backup airports share the same country context but differ by city, route network, and clock behavior.
OKJ-HIJ Hiroshima: 93 km, about 57m, +0h. OKJ-TKS Tokushima: 98 km, about 57m, +0h. OKJ-UKB Kobe: 126 km, about 1h 0m, +0h. OKJ-KIX Osaka: 132 km, about 1h 0m, +0h. These are distance and timezone references, not live flight availability claims.

OurAirports classifies OKJ as a large airport with scheduled service, which gives it stronger planning value than a code-only lookup.
OKJ (RJOB) is a low-elevation field at 806 ft (246 m) in the subtropics, kept in the curated set for its route, timezone, and market-planning value.
OKJ sits in a broader regional network with 5 nearby curated alternatives, so airline choice and connection strategy are part of the planning story here.
OKJ's runway record lists 1 runway, with the longest runway at 9,843 ft / 3,000 m and source surfaces recorded as asphalt.
Civil aviation oversight for OKJ runs through Japan Civil Aviation Bureau (JCAB); a more specific operator record is not currently in our source set.
These operational notes prefer the structured airport facts snapshot, then fall back to the accepted airport reference at okayama-airport.org, then blend that with local timezone, route, and city-access data already on this page.
These are the specific situations where this airport page earns its keep: time-zone conversion, city transfer planning, nearby airport backup logic, and source-confidence checks before acting.
OKJ uses Asia/Tokyo (JST, UTC+09:00). Use this before overnight arrivals, cross-date departures, and same-day connections.
Okayama Momotaro Airport is about 14 km from central Okayama; build that transfer into arrival and check-in planning.
HIJ Hiroshima is the closest retained alternate at 93 km, time difference +0h.
okayama-airport.org is listed as the official airport website in the airport facts snapshot; live schedules, gates, routes, terminals, and NOTAM-sensitive operations still need official airport or airline verification.

OKJ ranks #15 in the curated Japan airport set when large airports are listed before medium airports, then sorted by IATA code. The retained country set has 18 airports.
OKJ shares Asia/Tokyo with CTS Sapporo JP · FUK Fukuoka JP · HIJ Hiroshima JP · HND Tokyo JP · HSG Saga JP · ITM Osaka JP. This helps separate same-clock airports by city, country, code, and geography.
