Kobe Marui, Fashion retail complex in Sannomiya-chō, Japan.

Kobe Marui is a fashion building in Sannomiya-chō, Kobe, on the site of the former Phoenix Plaza, a Hanshin-Awaji earthquake recovery support facility. Takenaka Corporation built the six-storey structure; floors 1 to 5 hold 6,940 square metres of sales space, with floors up to 3 for women's goods, 4 and 5 for men's, and offices on the sixth floor. About 70 brands are represented.

Marui had long planned to enter the Kansai market and opened an office in Osaka in 1986, but the plan fell through and the office closed. Kobe Marui opened in 2004 on the site of the demolished Phoenix Plaza, a Hanshin-Awaji earthquake recovery support building at the Sannomiya intersection. It was Marui's first store in Kansai, built by Takenaka Corporation.

The name is read "Marui" though written "OIOI"; before opening, posters outside the store explained the reading, since recognition in Kansai was under ten percent. The first year drew about 4.5 million visitors, with middle-aged groups and mothers shopping with their thirties daughters. Local Kobe tastes shaped the floors: casual denim on the third floor sold less than the calmer second floor, so staff paired casual clothes with quieter bags.

The building sits near Sannomiya Station and features several entrances plus clear floor directories making navigation straightforward. During operating hours the different levels are easy to reach and finding your way inside is simple.

Marui's name recognition in Kansai was under 10 percent before opening, so the company handed out posters near the site reading "○I○I is read as Marui" and advertised with the phrase "'OIOI' written, read as Marui". The store opened as Marui's first in the Kansai region.
