Overview

C-one (シーワン) is a commercial facility — specifically a fashion building (ファッションビル) — located in Nagano City, Nagano Prefecture, Japan. It stands at the entrance of the Nishisenro-dori (二線路通り) street, directly across from the Zenkoji exit rotary of Nagano Station, an area lined with shops aimed at younger consumers. Because of this location, the building functions as a gathering point for the region's youth. The facility opened on October 10, 1980. Over the years its operation and management changed hands several times. At an unspecified point it came under the operation and management of Hankyu Shopping Center Development Co., Ltd. (now Hankyu Commercial Development Co., Ltd.), which carried out renovations. Later it came under the operation and management of RE-X Management Co., Ltd. On November 27, 2014, ownership passed to RF929 Co., Ltd., a wholly owned subsidiary of RF. C-one is organized across several floors. The fifth floor houses a cosmetic surgery clinic; the fourth floor has an ophthalmology clinic and miscellaneous goods; the third floor offers men's and women's fashion and sundries; the second floor has women's fashion, sundries, and a Saizeriya Nagano Ekimae branch; the first floor has women's fashion, jewelry, and a Starbucks Coffee Nagano Ekimae branch; and the basement level (BF) contains the LIVE HOUSE J music venue and restaurants. Business hours are 10:30–19:30, excluding the basement shops, Starbucks, and Saizeriya. A partner parking lot, the Minami-Ishido Shopping Street parking lot with 120 spaces, offers one hour free with purchases of 3,000 yen or more per store. The building is about a one-minute walk from Nagano Station on the JR and Nagano Electric Railway lines. A notable episode in C-one's history came in 2003, when a Starbucks Coffee store — the first in Nagano Prefecture — opened on the first floor as the Nagano Ekimae branch. It set a record described as the world's highest first-day sales for a Starbucks opening (about 3 million yen), drawing public attention.

History

C-one opened on October 10, 1980, as a commercial facility in Nagano City, Nagano Prefecture, positioned at the entrance of the Nishisenro-dori street across from the Zenkoji exit rotary of Nagano Station. The location, in an area lined with shops targeting younger customers, made it a gathering place for the region's youth. At an unspecified time, the facility came under the operation and management of Hankyu Shopping Center Development Co., Ltd. (now Hankyu Commercial Development Co., Ltd.), which carried out renovations. Later, again at an unspecified time, operation and management passed to RE-X Management Co., Ltd. A landmark moment came on June 27, 2003, when a Starbucks Coffee store opened on the first floor as the Nagano Ekimae branch — the first Starbucks in Nagano Prefecture. It reportedly set a record for the world's highest first-day sales for a Starbucks opening, about 3 million yen, which became a talking point. On November 27, 2014, ownership of C-one passed to RF929 Co., Ltd., a wholly owned subsidiary of RF. The building continues to operate as a multi-floor fashion and shopping complex, with floors devoted to women's and men's fashion, sundries, jewelry, clinics, restaurants, and a basement live house and dining area. Its official website continues to post news of store openings, events, and closures.
