Funnily enough I'm writing this in London right now, stuck here due to weather (oh well, there's way worse places to be stuck!). But let's get back to Tokyo...
Another of the neighbourhoods we totally loved was Shimokitazawa. It seemed worlds away from the buzzy shopping districts like Shibuya, and had a lovely lo-fi charm all its own with - again - tons of fantastic vintage shops, clothing stores and little places selling Japanese crafts and loads of great neighbourhood cafes. I made friends with a local who was hanging outside of a hair salon, and we hit the vintage motherload in a store called Haight & Ashbury which carried a beautifully curated collection and included that completely wacky and craft-tastic huge tree entirely knitted/crocheted of wool in the middle of the store. For more in Shimokitazawa check out BlinkLondon.
Finally, back on the design side of things and back in Shibuya we totally enjoyed a run through a department store called Loft which included a 60 Vision section, a cool collection of re-issued Japanese 1960's designed furniture (that's the Lobby sofa by Karimoku below), accessories and even some rather tasty looking cookies.
