Yoshinori Kataoka, President and CEO

The year 2020 marks 25 years of the Pioneer DJ business. In 2015 Pioneer DJ became independent of Pioneer Corporation as our own company. I'm proud of our success and would like to take this opportunity to offer my sincere thanks to the many customers who engaged with our products, as well as our suppliers and so many others who helped us to design and build those products. Thank you all for your understanding and support.

I formally assumed office as President of the company on January 1, 2020. As part of our commitment to continual organizational progress on the path toward further growth, we decided to change the company's name to AlphaTheta Corporation. The new name is inspired by alpha waves that are produced by the brain when relaxing to music and theta waves that are generated while creating music or when a person is absorbed in a performance. We want to position AlphaTheta as a provider of products and services that help people to reach their full potential through the medium of music and in turn fill the world with a sense of joy, wonder, and positive emotion.

AlphaTheta will continue to make an active contribution to the music industry through the development of innovative and attractive products and services for the Pioneer DJ, rekordbox, KUVO, TORAIZ and Pioneer Professional Audio brands.

We look forward to your continued support in the years to come.

Business overview

DJ and Club Equipment Business

Our core business, the DJ and club equipment business, has passed its 25-year milestone. In all this time, while enjoying a strong reputation among the world's top DJs and club professionals, our philosophy has always been to provide our customers with "wonder and emotion." In recent years, there's been an increase in the number of people who want to become professional DJs, as well as those who enjoy DJing with their friends and take it up as a hobby. We'll continue to offer a range of DJ equipment and applications tailored for these customers too. We aim to push ahead with innovative product development, design, and sales, so we can continue to lead the industry.

Professional Audio Equipment Business

Leveraging our experience in the DJ and club business, and the sound creation expertise that we've cultivated over many years, we develop and design club speakers and other types of professional audio equipment. In 2013, we introduced the XY Series of high-quality PA speakers and in 2016, the high-grade active PA speakers, the XPRS Series, enabling us to deliver the sounds of "wonder and emotion" from our audio equipment business also. We'll continue to work on product development, design, and sales in the pursuit of ever-more powerful, high-quality sound.


Music Production Tool Business

Our music production tool business serves the needs of music producers, creators, and live performers. We provide a range of equipment to support music production, such as professional samplers that enable music creators to quickly and intuitively reproduce musical phrases they've imagined, and tools such as monitor headphones and speakers that are essential for accurate sound production in the studio. In this field too, we aim to become the industry standard and we'll continue to pursue product development, design, and sales that can produce "wonder and emotion".

Application and Service Business

For dance music fans we provide an online dance community. In 2014, we started this new club culture entertainment service, KUVO, for clubs, DJs, and clubbers. Our aim is to create an environment where anyone who enjoys dance music can participate in KUVO anytime, anywhere, with anyone – to experience the same joy of dance music and DJs' performances found on the dancefloor, and communicate easily with each other while helping DJs get distributed royalities when their music is played in the club. We also develop DJ schools that channel "wonder and emotion" as part of our effort to spread DJ culture among more and more people.
