Female singer Erika performs outside of the south exit at Shinjuku Station, Tokyo, Japan.
Recently, this area outside of Shinjuku Station has become popular for performers to show off their artistry, whether by singing, dancing, or other performing arts, outside of the world's busiest train station.
As such, it's a great place to spend some time listening, observing, and even take photos and video of the performers. A unique way to take in the local culture, and perhaps discover new music.
