About IJ
IJ is a compact regional carrier operating primarily between Japan and China, which tells you almost everything about its strategic logic. With 14 non-stop routes spread across 8 airports, this isn't an airline chasing global domination — it's threading a specific needle in the Japan-China corridor, where demand is real, competition is fierce, and margins are thin. NRT serves as the operational center of gravity (7 of 14 routes flow through there), which makes Tokyo Narita less a hub and more the entire spine of the network. If NRT sneezes, IJ catches a cold.
Why fly IJ?
The honest case for IJ is geographic specificity. If you're moving between Japan and China — particularly into or out of NRT — IJ has built its schedule around exactly that flow. Nine routes touch Japan, five touch China, and the longest haul in the network is NRT-PEK at 2,135 km, which is a comfortable medium-haul distance that most carriers handle reasonably well. The total network spans just under 22,000 km, meaning IJ isn't pretending to be something it isn't. For travelers who want a carrier that actually knows its lane — rather than one that's stretched thin across four continents — that focus can translate into better operational reliability on the routes it does serve.

Tips for booking IJ
NRT is your use point with IJ. Seven routes originate there, so connections through Narita give you the most flexibility if plans change. The secondary hubs — NGB, PVG, and HIJ — each carry a single route, which means they're essentially spoke operations with limited recovery options if something goes sideways. Don't build a tight connection through Hiroshima expecting IJ to bail you out. Book directly where possible, check whether your fare class earns anything useful if you hold status elsewhere, and treat the single-route hubs as final destinations rather than transit points.
