Tokyo Designer's Block

worth going to? Of course if one happened to have the spare pile of cash to fund a flight and a weekend stay in Tokyo.

or is it a repeat of Milan/London etc…?

I think it’s worth to go to if you do not mind paying $ 500-$1000 usd (from China to Tokyo) flying there and closed to $ 100 per night for hotel.
Japanese design is very different from the European, their uses of material, shapes, color… it’s just interesting.
Tokyo is such a fun place to be. Don’t forget stop by Shibuya to get some cool night life sight-seeing.
