Jiyugaoka is one of Japanese ladies' favorites
Recently, the area surrounding Jiyugaoka Station was voted the place where young women would most like to live. In addition to the foreign brands that have shops there, there are literally dozens and dozens of independent shops and cafes. Great to just explore.
(Can be crowded on weekends. I recommend to go during the week. It is much less likely that you will need reservations for restaurants.)
