Wall jump in the room above, on the right wall of the doorway, immediately before the door transition. To get to the ledge: If the room above has normal physics, hold right in this room. If the room above has water physics, shoot to break spin while holding right in this room.

Wall jumping expands Samus' hitbox vertically, making it possible to trigger the door transition with upward momentum. Failing this trick will likely result in a soft lock.

Entrance condition:

{
  "comeInNormally": {},
  "comesThroughToilet": "no"
}

Requires:

{
  "notable": "Wall Jump Entry"
}
"canSuitlessMaridia"
"canPreciseWalljump"
"canPrepareForNextRoom"
"canMidairWiggle"
"canCarefulJump"

Dev note: Strat starts before entering this transition. FIXME: The midair wiggle is only needed if the room above has water physics. That's not something in the logic for vertical doors currently. Also if the room above is heated, these may require some heat frames to set up.
