Girl group NMIXX will hold a solo concert in Tokyo, Japan in August as part of its first world tour 'NMIXX 1ST WORLD TOUR (Episode 1: Zero Frontier)'. JYP Entertainment officially announced the news on March 4, first by opening NMIXX's official Japanese X (formerly Twitter) account at noon, followed by posting a concert poster at 6 p.m. According to the announcement, NMIXX will perform two shows on August 8 and 9 at Tokyo Keio Arena. This solo concert marks NMIXX's return to Tokyo approximately one year and two months after their previous fan concert tour 'NMIXX 2ND FAN CONCERT NMIXX CHANGE UP: MIXX LAB', which took place in January 2025 and from May to June. The 'hexagonal girl group' NMIXX is expected to showcase their solid performance skills and versatile charms at this welcome solo concert. Additionally, JYP Entertainment soft-launched NMIXX's official Japanese fan club on March 4 at 6 p.m. During the soft-launch period running until May 31, members who join will receive a set of six photo cards featuring images of the members. The official opening date for the full fan club will be announced later. With the launch of the official Japanese X account, the announcement of the solo concert, and the soft launch of the fan club, NMIXX is beginning full-scale activities in Japan.
