First Store in Gunma Prefecture! form forma Opens Formal Specialty Store in Takasaki City

Tokyo Soir Co., Ltd. (Headquarters: Chuo-ku, Tokyo; President and Representative Director: Junichi Koizumi), which develops women's formal wear, will open its formal concept shop "form forma" in Aeon Mall Takasaki (Takasaki City, Gunma Prefecture) on July 17, 2026 (Fri), marking its first store in Gunma Prefecture.

We will develop a store that makes formal wear more accessible to customers in Gunma Prefecture, an area where music and cultural activities are thriving.

[Background of Store Opening]

Takasaki City continues to develop as Gunma Prefecture's largest commercial city and is also attracting attention as a relocation destination from the Tokyo metropolitan area. According to the National Census, Takasaki City's household count in 2025 is projected to be 169,000 households, the highest in Gunma Prefecture, an increase of 2,600 households compared to five years ago. *1

The increase in household numbers is supported by childcare support measures such as free medical care for children up to 18 years old. Furthermore, to promote the settlement of families, Takasaki City offers a "Takasaki City Relocation Support Grant" of 1 million yen per household to those relocating from the 23 wards of Tokyo, with an additional 300,000 yen for households with family members under 18 years of age.

Meanwhile, Gunma Prefecture, including Takasaki City, is also active in cultural and artistic activities. According to a survey by the Japan Orchestra Federation *2, 148 orchestral performances are held annually in Gunma Prefecture, ranking second nationwide in the number of performances per 100,000 population. The Gunma Symphony Orchestra's total annual attendance exceeds 120,000, fostering a culture where many citizens regularly enjoy concerts and cultural events.

Against this backdrop, while there are many occasions in the Takasaki area requiring formal wear for events such as weddings and funerals, entrance and graduation ceremonies, recitals, and concert attendance, specialty stores where one can purchase formal wear along with related items like bags and accessories in one stop are limited.

Our company will offer a total proposal ranging from black formal wear, ceremony suits, and party dresses to related accessories, and as a community-based formal specialty store where "necessary attire can be obtained in one place when needed," we will meet the needs of customers in Takasaki City and surrounding areas.
