This is one of the advertisement for Muji
I really like his design Japanese graphic designer and curator Kenya Hara.
He is art director of Muji since 2001 and designed the opening and closing ceremony programs of the Nagano Winter Olympic Games 1998.
Kenya Hara is considered a leading design personality in Japan and in 2000 had his own exhibition “Re-Design: The Daily Products of the 21st Century”.
Here is some link about his design…
It is looks simple but it is let people feel like comes from our life and useful.
