With the spread of digital cameras, the minilab market shrank rapidly, and the company's performance substantially.

(Noritsu Precision, which originated from the photo processing equipment division of the former Noritsu Koki, has the largest share of the global market for film photo processing equipment, a market that will remain professional in the 2020s.)

Currently, as a holding company, the company focuses on the "manufacturing" business through Teibow, which has a 50% share of the global market for felt-tipped pen nibs, and AlphaTheta (formerly Pioneer DJ), a manufacturer of audio equipment known for its Pioneer DJ brand, which has a 70% share of the global market for DJ equipment, as well as the "healthcare" business through JMDC (formerly Japan Medical Data Center), a medical big data company.

Later, as Fujifilm and other major Japanese photographic equipment manufacturers began to develop their minilab businesses, Noritsu established Noritsu America in 1978, making it the first company in Japan to enter the North American market.

In the 1980s, Noritsu achieved great success in North America and became synonymous with minilabs in the U.S., gaining the top share of the global minilab market and the company expanded rapidly, becoming listed on the First Section of the Tokyo Stock Exchange in 1997.

DPE stores affiliated with photographic material dealers such as Fujicolor Shop installed minilabs made by their affiliated manufacturers, while other independent DPE stores often installed minilabs made by Noritsu.

Under the leadership of the second president, Noritsu Koki sought to continue the minilab business by forming an alliance with rival Fujifilm in 2006 to jointly develop a digital minilab, but the founding family (wife and daughter of Kanichi Nishimoto), Noritsu Koki's major shareholders, dismissed all directors in 2008.

In the fiscal year ended March 2010, Noritsu Koki posted a huge loss of 20.6 billion yen on sales of 27.9 billion yen, partly due to the impairment of the minilab business, and the company returned to profitability in the fiscal year ended March 2013.

Noritsu Precision, together with Fujifilm, was one of the last two companies to develop and sell developing machines for film photography, sharing the global market with Noritsu's QSS series and Fujifilm's Frontier series.

Noritsu Precision is the last of the two companies to develop and sell film photo processing machines.

In 2015, the company relocated its headquarters from Wakayama City, the site of its original business, to Minato Ward, Tokyo.

There are still some former affiliates in Wakayama City, such as Noritsu Precision Headquarters, which produces photo-related equipment.

In 2019, the company announced its mid-term management plan, setting its core businesses as "manufacturing" and "healthcare".
