During the day, 82-year-old Sumiko Iwamuro is making dumplings at the restaurant she’s been running for over six decades, but at night she’s taking over Tokyo’s nightclubs. After her husband died when she was in her 70s, Iwamuro started taking disc jockey classes for a year at a local music school. She then met an event producer and was introduced to the club scene where she is now known by her stage name, DJ Sumirock. Her music is predominantly techno with other bygone styles mixed in including jazz and French chanson. Although her music and restaurant are different, she compares the two saying, “In both, results can be seen immediately. If the customer eats what you have made, it shows on his face if it is delicious; and if a DJ is good, everyone will dance happily."
