Hi Angelia, I got some writeups here on Osaka shopping centers...
RINKU PREMIUM OUTLETS home to 119 stores including Bally, Coach, Fulra, Brooks Brothers and many more. Located 30 miles south of Osaka, on Osaka Bay - near the bridge to Kansai International Airport. In a relatively urban location served by a first-rate transportation infrastructure that brings shoppers by road, rail and air.
DIAMOR OSAKA an underground shopping arcade surrounded by seven stations. Was built according to the city planning to set main pedestrain passages underground to avoid traffic congestion on ground level. Diamor Osaka consists of four streets names Fashionable Street, Casual Street, Market Street and Variety Street.
HERBIS PLAZA located on basement second up through the 3rd floor in the building complex named Herbis Osaka with 190 meter high-rise which accomodates the world famous luxury hotel, The Ritz-Carlton Osaka and office tenants.
HEP FIVE a vertical shopping mall comprising of over 100 speciality stores, food/restaurants, amusement and an event hall. On the 7th floor, there is a spectacular Feris wheel that goes up to 348 feet high.
CRYSTAL NAGAHORI largest underground space in Japan with total floor area of 81,800 sq metres. Built as part of development for a major east-west transporation arterial of Osaka. B1F is a shopping mall with connection to 3 stations, with parking on B2F-B4F. Shopping mall stretches 730 metres with a total of 101 tenants, making up 9,500 sq metres of retail area.
HOOP a speciality store complex annexed to Abenobashi Terminal Building.
Think all these should be pretty easy to go to, since all near some stations.
