As is to be expected of a game set in Shibuya, TWEWY makes enough Shout-Outs to require a megaphone.
- A few pins in the Japanese version of the game are shout-outs to the big four gaming magazines in Japan (they were changed to stereotypical Japanese things in the international version).
- What should show up while reading minds but "Ouendaaaan!"? And the corresponding item (the Head Honcho outfit) has the characters for "ai rabu yuu"
. - The second ESPer Rank, after "Only Human", is "Spoon-Bender".
- The pins Lefty Cat, Brainy Cat, and Righty Cat make a trifecta of power, courage, and wisdom.
- In the English version in "Another Day", Higashizawa uses the phrase "Dilly dally, shilly shally" to lure contestants into Molco. This is widely known as the exceedingly confusing phrase blurted out by Tifa to Cloud in Final Fantasy VII: Advent Children in an attempt to make him put his past behind him about being powerless to stop Aerith's death. Neku, rightly, is confused. (The Japanese version instead had him say "motto motto", a motivational way to say something along the lines of "don't give up".)
- And on the subject of Final Fantasy VII, there's a food item called Mako Synergy.
- For Final Fantasy in general, there are pins named Bahamut, Ifrit, and Shiva. Progfox's "fusion" form and the attack it uses are pretty blatant references to some of Bahamut's incarnations, as well.
- One of the Swag items makes a shout-out to the original Final Fantasy, with Matoya's spell.
- Beat says "Booyaka!", a form of Totally Radical invented by Selphie from Final Fantasy VIII that failed to take off in that game, despite her best efforts.
- Talking with Hanekoma about Joshua's ability to 'see things', Neku will ask if he means "The 'I see dead people' kind of sees things?"
- Darkstalkers. Uzuki's battle sprite has her holding her arms in a manner identical Morrigan's signature fighting stance, and her and Kariya's Fusion resembles Morrigan's usual Level 3 Super with Lilith.
- Marble Sentai Slashman (or Tin Pin Slammurai in the english version) is a phenomenon in the world of TWEWY. Several NPCs are talking about it, and you can buy Slammurai costumes in Another Day.
- Rhyme's shoes look oddly familiar.◊ Also, Uzuki's reaction when she sees Kariya slacking off? "Kariya, you lazy bum!"
- Red's "It's all about manly spirits slamming into each other!!" is a direct quote from a certain man named Kamina.
- The shopkeeper of Molco's Tigre Punks is a punk-rocker named Nana. There's also the R-inscribed padlock necklace sold there.
- Before fighting Kariya (aka "Lollipop"), Beat says "How many licks could it take!?", referencing the famous Tootsie Pop commercial.
- In the US version, the Wild Boar shop has equipment called "Sabotage" and "3 MCs 1 DJ", both of which are references to Beastie Boys songs of the same or similar names.
- "Game Over", one of the tracks on the soundtrack, mentions 2channel in its lyrics.
