Overview

SunSunCity Mago (サンサンシティマーゴ) is a locally led shopping center located at 516 Kurachi, Seki, Gifu Prefecture, Japan. It is operated by Sun Strace Co., Ltd. (株式会社サン・ストラッセ), a company established in April 1988 with headquarters at the same address in Seki. The center opened on September 23, 1994, with Jusco Seki Store as its core anchor and 57 specialty stores. Over the decades it expanded through multiple phases: a major enlargement in December 2000 that roughly doubled its floor area and increased tenants to about 100; the opening of the Cinema Hall in November 2003, which introduced the first cinema complex in the Chuno area; the addition of the Kurachi Onsen Mago-no-Yu hot spring facility in July 2010; the Sports Hall anchored by Himaraya in November 2010; and the Mago West complex in October 2017, which brought MEGA Don Quijote and Nitori among eight tenants. The center now comprises four main buildings—the Main Hall, Sports Hall, Cinema Hall, and Mago West—plus the hot spring facility. Its core tenants include AEON Seki Store (formerly Jusco Seki), Himaraya, Cinex Mago, MEGA Don Quijote, and Nitori. Sun Strace also operates a second hot spring facility, Tokoname Onsen Mago-no-Yu, which opened in 2015 within the AEON Mall Tokoname site in Tokoname City, Aichi Prefecture. The center is known for its community-oriented programs, including the Mago Kids Club launched in August 2008—one of the earliest such programs among shopping centers—and the Mago Point Card loyalty scheme. It also runs free shuttle buses on weekends and holidays from Seki Station on the Nagaragawa Railway. The facility has been a fixture of the Chuno region's retail landscape for over three decades, celebrating its 30th anniversary in 2024 with a major renovation of the Main Hall's second floor, including the opening of GU and expansion of UNIQLO.

History

Sun Strace Co., Ltd. (株式会社サン・ストラッセ) was established in April 1988 with its headquarters at 516 Kurachi, Seki, Gifu Prefecture, Japan. Its business scope covers the development, operation, and management of commercial facilities and hot spring facilities. The company opened SunSunCity Mago on September 23, 1994, in Seki City, with Jusco Seki Store as the core anchor and 57 specialty stores. In December 2000, the Main Hall was expanded, roughly doubling the floor area and increasing the number of tenants to about 100. On November 22, 2003, the cinema complex Cinex Mago opened in the new Cinema Hall, which also featured an amusement facility operated by SEGA; this was the first cinema complex in the Chuno region. In the same year, a Starbucks opened on the Main Hall's first floor where the Dream Plaza had been, causing the Dream Plaza to relocate to the second floor directly above. On July 17, 2010, the hot spring facility Kurachi Onsen Mago-no-Yu opened. In November 2010, the Sports Hall opened, anchored by the large sporting goods store Himaraya. In 2015, Sun Strace opened a second hot spring facility, Tokoname Onsen Mago-no-Yu, in Rinku-cho, Tokoname City, Aichi Prefecture, within the AEON Mall Tokoname site. On July 9, 2016, a connecting passage between the Sports Hall and Cinema Hall opened, directly linking the Main Hall, Sports Hall, and Cinema Hall and allowing movement between them on the second floor. On October 28, 2017, the mixed-use complex Mago West opened, featuring eight tenants including the first MEGA Don Quijote in the Chuno area and Nitori. On April 18, 2023, a Starbucks opened in the northwest Cinema Hall parking area. On September 13, 2024, to mark the 30th anniversary of its opening, the Main Hall's second floor underwent a major renovation, including the opening of GU and an expansion of the UNIQLO store area. The center is composed of four buildings—Main Hall, Sports Hall, Cinema Hall, and Mago West—plus the hot spring facility Kurachi Onsen Mago-no-Yu. The Main Hall is anchored by AEON Seki Store, the Sports Hall by Himaraya, the Cinema Hall by Cinex Mago, and Mago West by MEGA Don Quijote and Nitori. Cinex Mago is operated by Gifu Tochi Kogyo Co., Ltd., a local entertainment company that also runs the mini-theater CINEX and the revival cinema Royal Theater in Gifu City. It has eight screens with a total of 1,389 seats, and each screen has two wheelchair spaces. Sun Strace was also a central company in the movement to revive the Meitetsu Gifu City Line, Mino-machi Line, and Ibi Line, which were abolished on April 1, 2005, though the revival was not realized. The center is accessible by car from the Tokai-Hokuriku Expressway Seki IC, by community bus from the Mago-mae bus stop, and by free shuttle bus from Seki Station on the Nagaragawa Railway on Saturdays, Sundays, and holidays.
