* Some of the BEMANI musicians play their own games, with varying degrees of success. ''REFLEC BEAT'' sound director DJ YOSHITAKA has [[https://www.youtube.com/watch?v=Y1ANh5bzCfQ shown himself to be able to play his own game very well]], and DJ TOTTO is a Kaiden[[note]]highest ''[[KyuAndDanRanks dan]]'' rank[[/note]]-level ''beatmania IIDX'' player. Meanwhile, ''pop'n music'' sound director wac is somewhat notorious for his appearance at JAEPO 2013, where he shows that his ''pop'n'' abilities...have a lot of room for improvement. (To be fair, he ''did'' play Ongaku [EX], one of the hardest charts in the entire ''pop'n'' series.)
* BadExportForYou:
** Arcade BEMANI games are released not only in Japan, but also other Asian regions, such as South Korea, Taiwan, and Southeast Asia. Unfortunately, only the Korean versions are translated; players in other non-Japanese [=eAMUSEMENT=] regions don't get translated versions.
** BEMANI cabinets at Round 1 US locations are Japan-region, and thus come with all the perks of playing with PASELI and drawbacks of playing with regular credits. The problem: ''no Round 1 location in the US has PASELI enabled'', meaning that, among other things, you can't get extra stages in ''IIDX'' or anti-GameOver insurance on games that offer it.
* ExecutiveMeddling: Inverted with "Brain Power" being removed from ''VideoGame/SoundVoltex'' and ''VideoGame/{{MUSECA}}'': [[https://twitter.com/noma113/status/844211648566984705 it was NOMA and not Konami who chose to not have the song's contract renewed]]. Played straight in the reasoning though: [[https://twitter.com/noma113/status/844211994198650880 The contract gave Konami the rights to "Brain Power"]], and as such it could not be used in non-Konami media or gigs, not even NOMA's own, without having to ask Konami, and NOMA wanted to be able to have control over his own song. That said, NOMA has stated that it's not the ''permanent'' end to "Brain Power" as a music game track; [[https://twitter.com/noma113/status/844213993719832576 there's the option to modify and renew the contract at a future date]]. In fact, right after it vanished from ''Sound Voltex'', it re-appeared on the non-Bemani music game ''Neon FM'' (which also [[AscendedMeme ascended]] the meme associated with the song).
* FanNickname
** 185 BPM is known by some as the "Yoshitaka constant" or variants thereof, due to DJ YOSHITAKA's strong tendency to use this speed in a large number of his songs.
*** In fact, it's such a prominent constant in his songs that [[spoiler: people initially thought that Rche was DJ YOSHITAKA's alias simply because of the use of repetitive chords and its bpm.]]
** "Soflan", a term used for sudden and dramatic BPM changes. The term originates from "SOFT LANDING ON THE BODY" from ''VideoGame/BeatmaniaIIDX 2nd Style'', which shuffles between 79, 159, and 318 BPM. Bonus points if the song itself does not actually change BPM but the scroll BPM does.
* FanworkBan: From 2011 to 2015, the online service ''Programmed World'' allowed players on current BEMANI cabinets in [[NoExportForYou countries not served by the eAMUSEMENT network]] to enjoy functions and features that are otherwise exclusive to [=eA=]-connected machines. Unfortunately, in March 2015, Konami sent a cease-and-desist order to arcades running PW-connected cabinets as well as the PW staff, forcing the service to go offline. It is speculated that Konami is planning to expand [=eAMUSEMENT=] service to outside of Eastern and Southeast Asia, as on the same weekend, the [=eAMUSEMENT=] website [[https://twitter.com/polyphonicroom/status/574415118366175232 announced plans to provide global website service to players outside of Japan]], although whether this will actually lead to global [=eAMUSEMENT=] service has yet to be seen. (Hint: it won't.)
* HeAlsoDid:
** Naoki Maeda:
*** ...once went by another identity, ''Ensoniq Maeda'', and composed music for other Konami games, such as ''[[VideoGame/{{Gradius}} Salamander 2]]''.
*** ...is the producer of the ''VideoGame/CrossBeats'' series.
** kors k composed music for ''VideoGame/{{DJMAX}}'', under the alias ''Oriental [=ST8=]''.
** Tatsh, best known for "Xepher", has produced songs for ''VideoGame/{{Cytus}}'', under the alias ''Persona''. In Taito's music games ''Music [=GunGun=]!'' and ''VideoGame/GrooveCoaster'', he produces songs under the alias ''Xeami'', although he also makes songs under his usual "Tatsh" handle.
* KeepCirculatingTheTapes: At least ''[=DanceEvolution=] Arcade'' gets offline kits. As for ''Miraidagakki''? There's no legal way to play it anymore, and ''[=BeatStream=]'' will fall to the same fate on September 1, 2017.
* NoExportForYou:
** If you were to make a pie chart of the number of BEMANI games released in Eastern and Southeast Asia and the number of BEMANI games released overseas, the result would be Pac-Man with a nearly-closed mouth. It got worse in 2012 when Konami started requiring BEMANI games to be connected to the [=eAMUSEMENT=] network, as well as making their games lease-only as part of the [=eAMUSEMENT=] Participation program rather than outright purchasable. . There are efforts to run a third-party clone of the [=eAMUSEMENT=] network, but see FanworkBan above for what this can lead to.
** [[Music/{{VOCALOID}} "Senbonzakura"]] is available on five different BEMANI games...but that number drops to ''one'' if you're playing in South Korea.
* {{Vaporware}}: ''Otoiroha'' was shown at JAEPO 2016 but ended up being quietly cancelled nearly a year later.
