DJ-Exclusive Room "DJ ROOM in BIG ECHO by AlphaTheta" Opens Second Location at Big Echo Nerima on July 3rd

Dai-ichi Kosho Co., Ltd. (hereinafter, "our company"), in collaboration with DJ equipment manufacturer AlphaTheta Corporation (hereinafter, "AlphaTheta"), will open "DJ ROOM in BIG ECHO by AlphaTheta" (hereinafter, "DJ Room") at Big Echo Nerima store (Nerima-ku, Tokyo), operated by our group company Josai Dai-ichi Kosho Co., Ltd., on July 3, 2026.

The first DJ Room was newly established at Big Echo Nakameguro Yamate Dori store in November 2025 with the aim of making DJ equipment more accessible. Customers can casually experience AlphaTheta's professional DJ equipment, which boasts an overwhelming global market share, and immerse themselves in DJ play without worrying about volume in the highly soundproof environment unique to karaoke rooms, gaining support primarily from young people.

To allow more customers, including DJ beginners and groups of friends, to experience DJing in their daily lives, we are opening our second DJ Room at the Big Echo Nerima store, located in front of the station on the railway line. It offers an easy way to engage with DJ culture as an entertainment option that fits into daily life.

The room is equipped with DAM's flagship model "LIVE DAM WAO!". It is a hybrid space where customers can enjoy not only DJ play but also the latest karaoke.

Our company will continue to develop attractive stores and services that meet customer needs and pursue customer satisfaction, aiming to become a karaoke store chosen by more customers.
