Overview
INTJINTPENTJENTPINFJENFJINFPENFPISTJISFJESTJESFJESTPISTPISFPESFP is a song by the Japanese rock band 3markets[ ], fronted by vocalist and guitarist Takafumi Kazama. Its title, at 64 characters, is the longest song name in the maimai series, surpassing the previous record held by the similarly maximalist 私の中の幻想的世界観及びその顕現を想起させたある現実での出来事に関する一考察. The title is a single unbroken concatenation of all 16 personality types from the Myers-Briggs Type Indicator (MBTI): INTJ, INTP, ENTJ, ENTP, INFJ, ENFJ, INFP, ENFP, ISTJ, ISFJ, ESTJ, ESFJ, ESTP, ISTP, ISFP, and ESFP.
Released for maimai でらっくす CiRCLE on January 16, 2026 as a Japan-exclusive POPS&ANIME track, the song carries a deliberately ironic lyrical stance. While the title parades the full MBTI taxonomy, the lyrics push back against reducing people to four-letter acronyms. Lines such as "I can't understand you with four alphabet letters" (アルファベット4文字で あなたのことはわかんねぇ) and "I don't want to be diagnosed without my consent" (勝手に診断されたくねえ) voice frustration with unsolicited personality typing, while the chorus repeats the demand not to categorize friends. The music video was directed by Yasuyuki Yamaguchi (山口保幸).
The song originally appears on 3markets[ ]'s self-titled 2024 single/album, as well as their major-label debut album SUPER DUST BOX. The band, led by Kazama Takafumi, was previously active under the name 3markets(株) until October 2014.
The maimai charts were designed by はっぴー, who signed the MASTER chart under the pseudonym はっぴー(INFP), a self-referential MBTI joke, as INFP is one of the 16 personality types. The MASTER chart (level 13, constant 13.3) stands out for its high Slide note count of 176 out of 926 total notes, characteristic of はっぴー's design style.
