EVOLUTION
YUKI Precision Co., Ltd.
1950
Saburo Otsubo founded Otsubo Screw Manufacturing in Honson, Chigasaki.
The company started as a small screw factory. Back then, we focused on producing tiny screws for use in communication equipment and similar devices. We machined them using a lathe—a machine that rotates parts—and employed various handmade tools to achieve diverse shapes.
We produced products with such high precision that it was hard to believe they were made by hand.
1961
Relocated to Yahata, Chigasaki City and established Yuki Precision Industries Co., Ltd.
The company name has been changed to Yuki Precision Industries Co., Ltd.
1982
NC Automatic Loading System Implementation
By the 1980s, the era of NC [numerical control] automatic lathes arrived, replacing cam-type automatic lathes. NC automatic lathes did not require creating dedicated cams when switching products; instead, they produced various shapes by rewriting the program.
While they couldn’t match cam-type automatic lathes in terms of the time required to machine a single part, they held an overwhelming advantage when considering design flexibility and setup speed. Yuki Precision switched all its automatic lathes to NC by the mid-1990s.
1991
Technological Innovation and Production System Transformation
In 1991, we introduced NC machining centers, achieving process consolidation and high-precision machining. Following the collapse of the IT bubble in 2001, we shifted from mass production to high-mix low-volume production, steering our course toward orders for high-value-added components.
2006
Launch of the Development Department
In addition to our existing precision component machining, we have established a mechanical design department to meet the challenging demands of manufacturers and research institutions.
Currently, all product development for YUKISEIMITSU AUDIO is conducted within this design department. The fusion of precision machining technology and design expertise enables us to create truly unique audio equipment.
2010
Aquired Aerospace QMS JIS Q 9100:2004 Certification. [Chigasaki Factory]
This enabled the production of parts meeting international quality requirements, leading to expanded business in the aerospace sector.
2011
First-time exhibitor at the Paris Air Show, the world's largest aerospace trade show
Through disseminating our technology on the international stage, we pursued expansion into the global market and the creation of new business opportunities.
2015
Establishment of French Subsidiary “YUKI Précision SAS” / Chigasaki Plant Obtains Medical Device Manufacturing Registration Certificate
We obtained a medical device manufacturing registration certificate, enabling us to manufacture components for the medical field.
We established an advanced quality management system, achieving expanded business with medical device manufacturers.
We established a wholly-owned subsidiary, “YUKI Précision SAS,” in Lyon, France, advancing the expansion of our overseas operations.

2021
Won the analog Grand Prix Special Award
“AP-0” won the Grand Prix Special Award in Analog magazine, Vol. 71.
2022
HIGH END MUNICH / OTOTEN First-Time Exhibitor
At HIGH END Munich, the premier international audio trade show, we made our overseas debut with the analog record player “AP-0.” The booth drew large crowds, demonstrating strong interest in the product and resulting in a highly successful event.
That same year, we also made our first appearance at an audio event in Japan through a joint exhibition. During listening sessions, so many visitors came that the room couldn’t hold them all, and our commitment to sound quality and design resonated deeply with many.
2023
Announcing the Analog Record Player AP-01 / Full-Scale Launch of Overseas Expansion
Announcing the analog record player “AP-01”. Developed as a flagship model based on the “AP-0” with all functions completely redesigned. This launch also marked the full-scale start of overseas exports, accelerating our expansion into the global market.
2024
Announcing the AP-01EM Analog Record Player with Armless Design
AP-01EM
Building upon the AP-01’s inherently vivid musical experience, we developed the AP-01EM to maximize the unique character of each manufacturer’s tonearm.
The turntable achieves “empathy” with the arm, delivering a new value where sound and technology merge.
Analog Quarterly VOL.83: Awarded the highest honor, the Gold Award
The AP-01 received the highest honor, the Gold Award, at the analog Grand Prix 2024 hosted by the audio specialist magazine analog (published April 3, 2024).
2025
The AP-01 was featured in the January 2025 issue of the U.S. audio magazine “The Absolute Sound.”
The AP-01 was featured in the January 2025 issue of The Absolute Sound, a world-renowned audio magazine founded in 1973.
It received high praise in a review written by Michael Fremer, a widely recognized music journalist in the high-end audio industry.
