Muji is holding an exhibition to celebrate 30 years of making its own music for its minimalist household goods, clothing and stationary stores. While your mileage may vary on how exciting that sounds, the company clearly knows what it’s doing, design-wise, with numerous awards and international stores to its name, so it might be worth your time. The exhibition is being held at its flagship Yurakucho store. There’s a map in the link above.
Incidentally, since we’re all cheapos here, Muji have a loyalty card app for smartphones called Muji Passport. You can earn ‘Muji Miles’ in return for surrendering your consumer data which apparently leads to various perks, one of which is a 500 yen discount you receive in the month of your birthday.
