P4 Parking

3,087 outdoor spaces right at Haneda T2 in P4

P4 Parking sits by Terminal 2 at Haneda and holds 3,087 spaces, making it the biggest short-stay option in the T2 cluster. It’s marked by the airport as an outdoor facility with reservation parking, so you lock in a spot but your car stays exposed to sun, rain, and winter dusting instead of under a roof like P1–P3.

Haneda codes this as a Terminal 2 short-stay lot, so this is the straightforward choice if you’re flying ANA or other T2 carriers and want to park close. It’s inside the main P1–P5 complex, charged on the same structure as the other terminal lots, and typically suits trips of a few hours up to several days rather than long-term off-airport pricing plays.

The key angle: P4 is the only T2-area lot explicitly flagged for outdoor reservation parking, while P1–P3 don’t carry that same note on the airport site. You can reserve through Haneda’s system and still keep flexibility: one FlyerTalk regular reports terminal parking reservations are 100% refundable up to eight days before your parking date, which makes it easier to hold a slot while your flight plans settle.

Watch out for crowding warnings on Haneda’s own parking page: in peak holiday periods across P1–P5, the airport says you might face several hours of wait time just to get into the complex. That’s not just a P4 issue, but if you’re relying on day-of drive-up, it can blow up your schedule and kill any time savings from being right at T2.

Practical tip: in Golden Week, Obon, or New Year, treat the several-hours-possible entry delay as real and pair a P4 reservation with an earlier airport arrival than usual, so you’re not watching departure time tick closer while queuing for the barrier gate.
