This is the flagship store of a fun chain of discount shops selling mainly electronic products all over Japan. It’s found near the west entrance of Shinjuku Station. Comprising nine specialised stores, including those for cameras, watches, games and repairs, it is a must-visit destination for appliance fanatics. The store sees around 80,000 visitors every weekday, and almost three times as many at weekends and on holidays. They hold regular classes for PC novices (bookings required).
