- Cash Cow Franchise: This series was one of Konami's cash cow back in the late 90s, especially the first game. It had so much merchandise, it even had books detailing said merchandise. Here is a page for a Mad Scientist in the game called Yuina Himoo. And she's not even the main girl, nor the top 3 popular. Yet just her alone spawned so much merchandise, including utensils, albums and pillows.
- Creator Couple:
- With Omi Minami voicing Tamami, both husband and wife seiyuu have now worked for the TokiMemo series. Her husband is Yuji Ueda who played Yoshio in the original Tokimemo game and later Motoharu in the Girl's Side: Second Kiss game.
- With Show Hayami who voicing Goro and his wife Rei Igarashi who played one of the main datable girls Mira Kagami in the original TokiMemo game, another husband and wife seiyuu team have now both appeared in the Tokimemo franchise.
- Executive Meddling:
- Back then, Konami organized a character poll on the famous magazine Famitsu, in which the readers would decide which character will become the heroine of the second Drama Series game, the would-be Irodori no Love Song. Despite the poll results giving a large victory to Miharu Tatebayashi, for various reasons the producers decided to go with the poll runner-up, Ayako Katagiri. They still later recognized Miharu's popularity by making her the co-heroine of the 3rd Drama Series game, Tabidachi no Uta.
- More recently, as part of the streamlining of their business practices, Konami has outright ended the Tokimeki Memorial series, with no new games in the main series since 2009, and the last major spin-off was in 2012.
- Fan Translation:
- The SNES version of the first game is sadly notable for having lots of attempts at creating a translation patch; all of them invariably went to stall for a reason or another.
- However, fans did extensive work on the first Tokimeki Memorial Girl's Side game for the Nintendo DS during 2010, and a full, bug-free translation patch was released in December 2010. The Tokimeki Memorial Girl's Side 2 translation was finished and released in May 2011.
- Follow the Leader: It's the game series which defined the non-hentai Dating Sim genre, after all.
- Keep Circulating the Tapes: All of the main series games are out of print. As a result, they tend to be sold at high prices on Amazon and other retailers, locking out players who started with the new generation of games unless they use emulators or have a friend willing to loan them a copy. While the first and second TokiMemo games are available on the PlayStation Network and the original release of TokiMemo is available on the PC Engine Mini as of 2020, the wallets of those without a PlayStation 3, a PlayStation Portable, a Play Station Vita, a PC Engine Mini or who would rather play the games on their original systems are in for a rough time.
- Name's the Same: Kasumi Asou must not be confused with the Phantom Thief of the same name of City Hunter. When their names are written in Japanese, the only difference is their first name, City Hunter Kasumi's being written in Hiragana, while Tokimemo 2 Kasumi's is written with Kanji.
- No Export for You: None of the games are available outside of the Japanese language (bar the first game).
- One-Hit Wonder: Yumi Saotome is the only role her seiyuu Yoshiki Kurin ever voiced.
- Portmanteau Series Nickname: "TokiMemo"
- Post-Release Retitle: The first TokiMemo game added the forever with you subtitle when it was re-released for the PlayStation in 1995, the Sega Saturn in 1996, Windows 95 in 1997 and the PlayStation Portable in 2006. For the Super Famicom re-release, the Densetsu no Ki no Shita denote subtitle was added.
- Referenced by...: Being a defining and popular game series in Japan, the Tokimemo games got their fair share of those in pop culture. To cite a few works containing such parodies: Excel Saga, Gintama, Great Teacher Onizuka, Kochikame, La-Mulana, Gravity Falls...
- Remade for the Export: In 2007, Konami tested the waters in America by creating Brooktown High, an American High School version à la Sims of Tokimeki Memorial. But what they failed to notice, is that what made the success of Tokimeki Memorial is its beautiful anime graphics, and its humor and light-hearted atmosphere; no wonder a game with fugly 3D designs, insipid characters and crappy dialogue like Brooktown High, already not helped by its concept and by virtually non-existent publicity, bombed royally.
- Star-Making Role: Mami Kingetsu became famous for her role as Shiori Fujisaki and went on to have a successful career.
- Talking to Himself: Hikari Tachibana voices both Shirayuki twins, and as such this occurs in a few scenes where both are present (most notably the Girl with Psycho Weapon scene described above, as well as the scene where they finally reveal their switcheroo game to the protagonist).
- What Could Have Been: According to the Japanese version of The Other Wiki, Yukari Koshiki is a shining example of this trope. Indeed, Yukaris initial name was Shouko Hoshino (星野翔子), but because the PC-Engines Kanji system couldnt display the kanji 翔 (shou), her name was changed to the current Yukari Koshiki. Even more memorable is that, in the games developments initial stage, she was planned to be the games second heroine at Shioris side (and be hostile towards her), but the idea was ultimately scrapped. Her personnality was also radically different: she was planned as a Delinquent instead of the Cloud Cuckoo Lander she is in the final version. Finally, there was a planned game sequence in which, when you phone her to set a date, sometimes the call would be redirected to her Overprotective Dads cellphone: a brilliant idea that was also scrapped in the end. Several of those ideas would be used 15 years later in Tokimeki Memorial 4, to create Yukari's Expy, Kai Ryukochi.
