Lucua1100 is a shopping mall attached to Osaka Station. It runs from two basement floors to ten floors above ground, holding fashion and cosmetics stores, Muji, Tsutaya Books, and restaurants. Shopping floors open from 10:30 to 20:30, and the restaurant floor on the tenth floor operates from 11:00 to 23:00. On Sundays the bookstore is crowded, making it hard to browse at an easy pace.
