hi.. i wan to visit the osaka market. is it worth going if i go around 10am? after a lunch there, i thought of making a trip to sayamaike museum, a building by Tadao Ando. is it far from osaka town? i understand that i can take the Nankai Koya Line , and exit at the Osakasayamashi Station. How far will the journey be? I will be staying at the Swissotel Hotel, is the namba station (the one at the bottom of the hotel) where i take Nankai koya line?
