I updated my shop last night and more magazines have been added! (backnumbers/mostly secondhand)
For the past 5-6 years there has been SO MANY lifestyle/home/interior magazines published in Japan, and everytime I go to the bookstore I find something new and they really do inspire me. ku:nel, Lingkaran, Arne, Tennen-seikatsu, Come home! are the popular ones that have been around for quite a long time (unfortunately Lingkaran is now finished) , but the newer or not-so-big-but-actually-quite-good zine-type ones like hibi, murmur, miru by Shiseido can't be missed.
Also though I don't have it in my shop at the moment "kurashi no techo" is the all-time favourite, it's been going since 1948 and is probably the oldest lifestyle magazine in Japan. It's a really great magazine full of useful and inspiring ideas for quality lifestyle, but it has lots of reading stuff so you'd enjoy it more if you read Japanese. Still it's really worth checking out, if you happen to go near a bookstore that sell Japanese magazines do look for this writing "暮らしの手帖"!!
