Message

Our DJ business began as a division of Pioneer Corporation in 1994, introducing the world’s first commercially available flat-top DJ CD player, the CDJ-500. It was praised by forward-thinking DJs and, as word spread throughout the dance music world, it received much media attention, glowing reviews, and prestigious awards. As part of the team involved in the design of the CDJ-500, I still vividly remember my pride when it received the highest accolades at international exhibitions.

In 2025, we mark the tenth anniversary of our independence from Pioneer Corporation. Over the past decade, we’ve grown our business, thanks to the unwavering support and collaboration of our customers, partners, and industry professionals. We would like to express our deepest gratitude, so, thank you. This milestone isn’t just a celebration of our past ten years – it’s also the beginning of many more to come.

We’ll continue to evolve while staying true to our roots, create innovative products and services, and strive for the development of the music industry and its culture. At the same time, we’re committed to remaining a company that society values and depends on. We look forward to another great year in music and hope you will continue to support AlphaTheta. As always, everyone at our company will take on new challenges each day to achieve our mission: “One Through Music.”
