Notes
Oitsu has two side platforms linked by an unguarded — no signal, no gate — at-grade walkway, plus one storage siding and one former freight siding that is still used occasionally for rolling-stock deliveries and long-term storage. The station is also pressed into service as the turn-around point for test runs on the Atsumi Line.
