LUMINE EST
Located right by JR Shinjuku Station East Exit, this is a fashion building with convenient access. Many fashion, fashion accessories, interior goods, cosmetic shops are located between B2F and 6F. The shops are open late in the evening so it is easy to drop by on the way home.
I originally just came here with a friend to eat at the PINGU-themed restaurant, but after eating, I found a ton of women's clothing stores and ended up going on a shopping spree! Guys don't need to worry—there are some men's stores too, just not as many. There are also plenty of restaurants to choose from, so after shopping till you drop, you can grab a bite and then shop some more.
