Template:THE iDOLM@STER Game Infobox THE IDOLM@STER (アイドルマスター Aidorumasutaa?) was an arcade game released on July 25, 2005, where the player becomes the Producer of a new talent agency called 765 Production where their main goal is help produce their newly scouted idols.

With the popularity of the game, it received a Xbox 360 port on January 25, 2007 under the same name.

The termination of the game's online service and mobile site was announced on May 28, 2010, and officially ended on September 1, 2010[1]. In October 2017, repair support was also terminated[2][3].


The Producer has a choice of nine idols from 765 Production to produce. In the beginning, the Producer can only choose one, but as they gain more experience they'll be able to produce up to three and make them a unit with a custom name. With the selected idols, the game depicts the activities between the Producer and idols for a day within an in-game week.

Players can also compete against other Producers in Japan with the "Newcomer Producer" network, which would rank them based on their performance as a Producer.

Idol and Unit Production

The process of producing idols and units are the same, and the production follows this general flow:

  1. The player selects the idol(s) they wish to produce.
  2. For units, the player then chooses the unit name.
  3. The player will gain fans with their idol(s) by completing Lessons, Communications, or Auditions.
    1. With Lessons, the idol(s) will mainly increase their stats and fan gain will relatively low. The same applies to Communications, where the idol(s) will build up Memories to be used in Auditions.
    2. With Auditions, if the idol(s) succeeds, they will be able to make TV appearances to gain fans and the amount of fans gained corresponds with the level of the Audition. However, if they fail to pass the audition, their fan count will decrease, but there is a rare chance that it will increase slightly,
  4. If the required amount of fans are gained, the rank of the idol(s) will increase. However, if they fail, the idol(s) will no longer be able to do any activities and a retirement concert will be held.


The Office serves as a main screen as players start their production here in the Morning, and return after completing which production style they chose to complete at Night.


In the morning, the player can:

  • Check the date and how much time is left in the production period, the rank up limit, and how many of fans the idol(s) have.
  • Choose to either greet the idol(s) to begin work, or give them the week off.
    • If a player gives their idol(s) two weeks off in a row, they will have the option to retire.
  • See their options of Lessons, Communications, or Auditions.
  • Change the song or costume for Auditions.
  • Choose their production style for the week.


At night, the player can:

  • See the rank of the idol(s) and the rank up limit after the production for the week.
  • See fan mail, presents, or letters of misfortune.


With the selected idol(s), the Producer has three in-game activities to complete to gain experience: Lessons, Communications, and Auditions.


Lessons are made up of five mini-games: Voice Lessons, Pose Lessons, Lyric Lessons, Dance Lessons, and Expression Lessons. The goal of these lessons are to level up an idol's four main stats: Dance, Visual, Vocal, or Character. The lessons are divided into six parts, and the overall performance in each part will be ranked from Bad, Normal, Good, or Perfect. However, unlike the other activities, Lessons aren't always available.


Communications have the Producer talk with their chosen idol, along with choosing jobs for their idol to complete to raise their idol rank. These will create good or bad memories for the idol which will be ranked from Bad [4], Normal [5], Good [6], and Perfect Communication [7]. The memories created can then be used during auditions and lives.


Auditions have the Producer choose a song and costume for their idol to perform and wear while they are judged to determine if they pass or fail. There are three types of Auditions: Limited, National, and Special. Limited Auditions are for idols ranked E or F,  National Auditions are for idols of any rank, and Special Auditions can only be done after completing certain conditions. Once the audition type is chosen, Producers will be matched with other players who are currently doing the same audition type or matched with random NPCs. 

During the audition, three judges representing the Vocal, Dance, and Visual stats will give out points depending on the idol's appeal. The interest level is represented by gauges which will increase or decrease depending on the success of the appeal which is determined by staying within the song's rhythm and the good memories used. Each audition is made of three segments with nine attempts at an appeal proceeded by a mid-audition review, and at the end of each segment the idols with the three highest scores in each category will receive stars and idols with the lowest scores in each category will lose stars. The amount of stars your idol has at the end will determine if they pass or not.

If the idol is able to pass the audition, they will be able to do a televised performance with the song and costume previously chosen which will increase an idol's fan count and in turn their rank.


If an idol or unit is unable to reach the minimum rank within the required period, the idol or unit is able to reach the maximum rank by the end of the period [8], or the idol or unit has taken the week off two times in a row, a Retirement concert will be held. The process of the the Retirement concert follows:

  1. Venue Selection
  2. Costume and Song Selection
  3. Communication
  4. Concert
  5. Communication
  6. Credit Sequence

Development and Cabinet

The development of the game began in 2001, with Namco designer Akihiro Ishihara's desire to create a game that would utilize the progress-saving magnetic stripe cards found in some arcade games. With the main goal being a game that players would return to everyday, in order to create an emotional bond with the characters, a raising simulation where players befriend girls and young women was chosen.

To fit in with the competitive nature of other arcade games, the characters were to be idols where players raise their own to compete against others to become the top idol. In order to create realistic characters that weren't perceived as being too moe, various idol groups, such as Morning Musume, were used as inspiration for designs by Toshiyuki Kubooka.

The game was announced at the All Nippon Amusement Machine Operators' Union in February 2004. Despite worries and criticisms that the game would be awkward to play or unsure in its premise, when the game was tested in arcades, it's popularity quickly spread through word of mouth.

The design of the cabinet consists of a live tower and the touchscreen Rewritable Stage arcade cabinet. On the live tower, the nationwide rankings and TV appearance images of the idols are displayed, but can be easily skipped to the next ranking display. The main station cabinet has a touchscreen display in the center, a coin slot and headphone jack on the right side, and a card slot on the left side.

Mobile Site

During the run time of the arcade game, multiple iterations of a mobile tie-in were made.

Happening ☆ Location

This was the first mobile title, released in July 2005. The main premise is a Sugoroku-like game, where by rolling die, players could visit real life locations and obtain in-game items and communication events with an idol. The game could be found on DoCoMo, SoftBank, and au devices, as well as some BREW devices, or a lower-quality web version could be played. Each idol was given a specific city, and also received an alternate casual outfit.

  • August 2005: "Happening ☆ Location Chihaya Kisaragi in Okayama"
  • September 2005: "Happening ☆ Location Azusa Miura in Nagoya"

  • June 2006: "Happening ☆ Location Yukiho Hagiwara in Hokkaido"
  • August 2006: "Happening ☆ Location Yayoi Takatsuki in Osaka and Kobe"

Arcade Link

This would allow players to link their phone to their arcade account. From this, they could view their status, nationwide unit rankings, and more.

Mail ☆ Please

After linking their phone to their account, they had a chance of receiving one of the following types of mail:

  • Registration Complete: a mail from an idol currently being produced.
  • Enthusiastic: a mail from when a new unit is produced.
  • Everyday: mail from an idol's daily life.
  • Boost Mail: if given a specific date and time, the tension of the idol will be at a fixed MAX for one week and stats will increase. This includes Enthusiastic, Link, and Audition mail.
  • Link: mail connected to an in-game communication event.
  • Audition: mail that corresponds with the result of an Audition.
  • Retirement: mail from the produced unit (excluding Yayoi) after retirement.
  • Mistake: mail from another idol (excluding Yayoi) that isn't being produced.

Memories ☆ Please

A tool that allows players to download still images from in-game TV appearances. In March 2006, players could submit their saved images for a calendar that would displaya new image everyday.

Accessory Shop

From points earned from Happening ☆ Location, they can be exchanged for Mobile Accessories or Arcade Accessories.


In the Office, players can form teams with one another.

Attendance Record​

A tool that allowed players to see which arcade and stores they've played at, as well as the number of times they played in a month. A campaign was run in March 2006 until the end of April, where players would be rewarded based on total number of times they played at a NAMCO store.

  • Create, play, and retire a new unit within the event period.
  • Enter the unit on the official mobile site.
  • The unit can only be produced with one song that cannot be changed once chosen. (THE IDOLM@STER is excluded.)
  • One or more of the Special Auditions[9] must be passed.
  • To rank the players, the number of fans by the players' retirement point would be added and adjusted by the idols included in their unit and the players' producer rank.
