OMORI has multiple locations players can choose to explore throughout the game's story. These segments are split into two different worlds: the imaginary world of HEADSPACE and the real world of FARAWAY TOWN.

Note that FARAWAY TOWN is only explorable if the player chooses to let SUNNY go outside by answering KEL knocking on the door instead of staying indoors. Another thing to note is that the BLACK SPACE areas all depend on the ROUTE taken by the player, following either a confined, linear story trajectory or an expansive, non-linear hub which can be accessed at any time.

WHITE SPACE You've been living here for as long as you can remember.	NEIGHBOR'S ROOM A memory-laden room where your best friends AUBREY, HERO, and KEL live. BIG YELLOW CAT watches over the trio, eagerly awaiting them to return from their latest adventure.	VAST FOREST A gentle glade surrounded by giant pinwheels. Located in the center of HEADSPACE, the soft inviting environment leads to a suitable home for many children.
OTHERWORLD A giant moon orbiting HEADSPACE. Luckily it never moves, as a ladder is the only means of getting there.	JUNKYARD Trash. Lots of trash. OTHERWORLD's local garbage dump that is filled with various pieces of trash and antiques the residents throw out everyday.	ORANGE OASIS Home of DINO'S DIG and a popular tourist spot, this dessert desert also holds it's fair share of mystery.
RAIN TOWN Where VEGGIE KIDS are born. It's constantly raining, which makes visiting uncomfortable no matter the time of year.	PYREFLY FOREST A huge, mist covered forest surrounding a giant castle. Spiders prey on the weak, and shadows whisper in your ears.	SPROUT MOLE VILLAGE A large village housing a majority of HEADSPACE's SPROUT MOLES. A lot of SPROUT MOLES died in the process of migrating here. Young SPROUT MOLE children born here have the privilege of not knowing that pain.
SWEETHEART'S CASTLE A massive castle owned by the titular princess, SWEETHEART. Holds a large SPROUT MOLE population, a majority of which live in THE DUNGEON.	NORTH LAKE A mysterious lake covered in fog and mist. It once held fragments of the truth inside a distant lighthouse. Remember, you've seen "her" leave through a curtain multiple times before...	LAST RESORT A seedy casino resort run by GATOR GUYS, all contractually bound to work forever with no pay. This is where you must reunite with your missing friends.
GHOST PARTY A party thrown by a dapper ghost, all managing to fit inside the confines of a swimming pool. Many describe this place as a spooky area but it isn't all that bad!	DEEP WELL A long toll road with many roadside stops and a network of caves to aid fare evasion. Can either go on infinitely or not depending on the skill of the driver.	DEEPER WELL A cursed trench found at the bottom of the ocean, filled with unexplainable life and various forms of coral. Its residents seem to be aware of the truth surrounding HEADSPACE and their existence. Be careful of who to trust...
HUMPHREY The oldest lifeform in HEADSPACE not only houses three witches, but also has a fully functional laboratory built inside of him. Avoid getting on HUMPHREY's bad side and you'll be good to go.	SNOWGLOBE MOUNTAIN A secluded mountain sealed away for people who need to get away from it all. Nostalgia fills you with memories you're not sure you had.	THE ABYSS The subterranean chasm that few people enter, and even fewer leave. Some say those who stay too long are transformed beyond recognition.

FOREST PLAYGROUND A colorful playground where the youthful residents of VAST FOREST can play their games and have fun! MARI and BASIL are waiting for you to join their picnic.	BASIL'S HOUSE A peaceful old shoe that serves as the home of BASIL. When helping him fix the PHOTO ALBUM, BASIL discovers "something" horrible, one that he shouldn't have discovered in the first place...	PINWHEEL FOREST A windy and breezy forest located above VAST FOREST. Those who visit here often fly their kites to relax.
TRAIN STATION The local train station of VAST FOREST. Many are currently waiting for the train to arrive while ordering LEMONADE. There were originally more trains running before an unknown incident reduced the number to one single train available.	TRAIN A train surrounded by various shadowy figures and their luggage. The lights flicker constantly, and a strange creature suddenly emerges from the shadows.	SPACE BOYFRIEND'S HOUSE The crescent-shaped home of SPACE BOYFRIEND, who is currently lovesick over his recent breakups with the duchess SWEETHEART. See you, SPACE BOYFRIEND...

SMOL'S HOUSE The dragon-shaped house of SMOL, the world's smallest centaur. Gaze upon his many achievements he proudly presents to his audience!	PESSI'S HOUSE An obnoxious-looking house... where one of SWEETHEART's biggest fans presents his love for the duchess... even to the point of cosplaying as her.
TV GIRL'S HOUSE A tv-shaped house where TV GIRL runs her many programs while occasionally drinking COFFEE during her small breaks.	FROZEN LAKE A snowy lake where bystanders can buy frozen treats such as a SNO-CONE. The igloo there might lead to somewhere... very chilling and desolate.	CATTAIL FIELD A peaceful field filled with purple-colored cattail plants. It also serves as a great place to stargaze too. On some occasions, memories of the past slowly blend into these fields...
SPROUT MOLE COLONY The former residence of the SPROUT MOLES. Only a few remain here, trying to sustain their lives in an empty hole of nothingness... One can only hope someday they will slowly return to this place and start rebuilding.	DINO'S DIG The main attraction of ORANGE OASIS, hosted by the founder DINO and his dino buddies. Have a Dino-tastic adventure digging out new treasure!	BREAVEN A dough dungeon. Rumor has it that two eccentric twins reside there making bread for all eternity while guarding ORANGE OASIS under their watchful eye.
DONUT HOUSE A donut-shaped house full of sentient donuts! One of them appears to be the grandmother of SWEETHEART... How interesting.	RELL'S HOUSE A small, crowded home where RELL and his family reside. While there's not much happening there, it sure is a sight to see this chaotic family!	PALMIE'S HOUSE The warm cottage of PALMIE, who takes in any children lacking families to give them a house where they can feel safe and comforted.
ORANGE JOE'S HOUSE The home of the optimistic ORANGE JOE and his brother ORAGNE JOE. As they always say: Hope and vigor! Hope and vigor!

THE ROYAL LIBRARY A long library filled with various books. The GUEST MOLE there is currently trying to dispose of any guests that don't match the dress code.
THE ROYAL THEATER The movie theater within SWEETHEART'S CASTLE is filled with tons of movies... that only showcase SWEETHEART's beauty. Nonetheless, watching them is an intriguing sight for all visitors	THE ROYAL KITCHEN The kitchen needs more people to help them bake a delicious cake. Be careful not to make a mess here for the CHEF MOLE!	THE ROYAL BALLROOM Various guests dance here, and the SPROUT MOLE choir needs some encouragement and motivation. Just make sure to continuously pelt them with tomatos to keep the show going.
LOST LIBRARY An abandoned, long forgotten library filled with old excerpts containing memories of someone's past, buried deep underground. It once contained remnants of the truth before being moved somewhere else.	CLUB SANDWICH A series of local bar joints owned by both HOAGIE and REUBEN. Many who come here often lounge and drink away their sorrows.	MUSTARD SUB DEEP WELL's local cafe run by five mermaid sisters, and is well-known for its deliciously baked cheeseburgers.
BOSS RUSH A simulator located deep inside of HUMPHREY. Challengers have the option to refight bosses from the main story to earn four trophies. What a thrill!	BORING ROOM Also known as the LAMP ROOM. The BORING ROOM is a plain room that appears to be simple and clean as it is. Presumably represents one's thoughts of longing for a better life.	NEIGHBOR'S BEDROOM After "rescuing" BASIL from BLACK SPACE, you find all of your friends sleeping. Once both of you fall asleep, you find yourself reliving another endless cycle of escapism. Only this time, you'll be PLAYING FOREVER.
