Oricon

• 1. Introduction

  ›

  Oricon is the name most Japanese music fans associate with a single question: what sold the most this week? But behind that simple chart number is a story that stretches back to November 1967, when a former milk products promoter named Sōkō Koike decided the Japanese music industry needed better data.

  Koike had worked for Snow Brand Milk Products before turning his attention to music. He founded Original Confidence Inc. that year, and within weeks the company was publishing a singles chart on an experimental basis. Few outside the industry took notice at first. The chart was, like the Tokushin Music Report that had preceded it since 1962, strictly a trade publication, available only to people who worked in music.

  What happened next is the real story: how Koike pushed his charts into living rooms across Japan, how the company grew into the closest thing the country has to a Billboard, and how a journalist's pointed questions about statistical transparency once landed Oricon in a legal battle that drew the attention of Reporters Without Borders.

  On the 4th of January 1968, the singles chart Koike had been testing went official. Its name was already in place, and the chart had structure. What it lacked was an audience beyond the industry insiders who received it.

  For roughly a decade, Original Confidence operated in that insider world, the same lane occupied by Tokushin Music Report since 1962. It was Koike who changed the trajectory. Through the 1970s, he ran an intensive promotional campaign across multiple media channels, including television programs. He was pushing not just his company's product but the very idea that a weekly chart ranking could matter to ordinary listeners.

  By the late 1970s, it had worked. The hit parade had become known to the general public by its abbreviated nickname, Oricon. Koike had essentially created a brand from a trade publication. The company's name caught up with the nickname in 1992, when it formally shortened its name to Oricon. Seven years later, in 1999, it restructured into a holding company with several subsidiaries.

  Sōkō Koike did not live to see all the chart categories his creation would eventually produce. After his death, Oricon passed into the hands of his relatives, and Ko Koike held the CEO role with a stake of 2.75% as of March 2012.

• 3. How the Charts Work

  ›

  Every Monday, data arrives at Oricon from roughly 39,700 retail outlets across Japan. By Tuesday, ranked results are announced and published in Oricon Style, the company's magazine, produced through its subsidiary Oricon Entertainment Inc.

  The process sounds straightforward, but there are meaningful gaps built into it. Certain retail channels simply do not report to Oricon. The pop group NEWS released a debut single exclusively through 7-Eleven stores, which fall outside Oricon's data collection. Those sales never appeared in the charts. Oricon itself does not claim otherwise: the company acknowledges its rankings are not a complete picture.

  Before electronic data collection, the entire system ran on faxes sent from record shops. The shift to electronic reporting removed some friction but did not eliminate coverage gaps. What Oricon does track spans a wide range: CDs, DVDs, video games, manga, books, and karaoke. The company also runs panel survey-based popularity ratings for television commercials, a service listed on its official website.

  On the 19th of December 2018, Oricon launched its Combined Chart, which pulls together CD sales, digital sales, and streaming data into a single ranking, reflecting how listeners were actually engaging with music by that point in time.

• 4. The Lawsuit That Tested Free Speech

  ›

  In 2006, a journalist named Hiro Ugaya gave an interview to Saizo magazine. In it, he questioned whether Oricon's statistical methods were transparent enough to be trusted, and suggested the charts might be skewed to benefit certain management companies and labels, specifically naming Johnny and Associates.

  Oricon's response was swift. On the 17th of November 2006, the company filed a lawsuit against Ugaya personally, not the magazine, accusing him of making mendacious comments. The damages sought were 50 million yen, which at the time equated to roughly 318,000 euros.

  Ugaya framed the suit as a SLAPP: a strategic lawsuit against public participation, a legal tactic designed to silence critics through the cost and burden of litigation rather than to vindicate a genuine legal wrong. NGOs rallied behind him, including Reporters Without Borders, which condemned the lawsuit as a violation of free expression.

  A Tokyo District Court initially found against Ugaya and ordered him to pay one million yen. He appealed to the Tokyo High Court, and the case dragged on for 33 months. Oricon ultimately dropped its claim. A settlement was reached in which the publisher of Saizo magazine apologized both to Ugaya for publishing inaccurate comments without permission and to Oricon for discrediting the chart. The publisher paid Ugaya 5 million yen. Oricon waived its damages claim, and Ugaya waived a counterclaim he had filed. No criminal charge was ever brought against him.

  Dropping a lawsuit is genuinely unusual in Japan. Only 0.1% of cases that concluded in 2007 ended because the plaintiff voluntarily walked away.

• 5. A Timeline in Charts

  ›

  The Singles Chart, which went official on the 4th of January 1968, is the oldest chart Oricon still publishes. The Albums Chart followed on the 5th of October 1987. In between, Oricon tracked formats that no longer exist commercially: an LP Chart ran from January 1970 through November 1989, and a VHD Chart covered the same period. A Cartridges Chart and a CT Chart both ran from December 1974 through April 1978.

  The Karaoke Chart launched on the 26th of December 1994, a reflection of how central karaoke had become to Japanese popular music by that decade. A Comic Chart started in February 1995, was suspended in March 2001, and then revived in April 2008 alongside new Book and Bunkobon charts. The Blu-ray Disc Chart began on the 7th of September 2008, and by October 2013 Oricon had a combined Music DVD and Blu-ray Disc ranking.

  Digital formats arrived later. A Digital Albums Chart launched in November 2016, a Digital Singles Chart in December 2017, and a Streaming Chart in December 2018. The breadth of that list tells its own story about how formats rose and fell in Japan over five decades.

  Looking at the top-selling artists by year reveals other patterns: Yōsui Inoue led in 1974, Pink Lady in 1977, Yellow Magic Orchestra in 1980, and Seiko Matsuda in 1984. B'z topped the chart in both 1991 and 1998. Hikaru Utada led in 1999, 2002, and 2004. AKB48 dominated from 2011 onward for several years, Arashi appeared multiple times including 2019, and BTS topped the annual ranking in 2021, the first non-Japanese act to do so in the table's recorded history.
