I was elated when I found that the Japanese section in Kinokuniya sold Japanese pattern books. Whenever I am there, I'd grab a few of them. Since they are in Japanese, it takes some time to understand the patterns but mostly fairly easy. I still think the US patterns are better. Very detailed with notches and step by step explanation, one can almost not get it wrong when sewing.
This is one of my favourite book by Yuri Kaneko. Simple sewing but with very elegant results.
The author and designer herself.
She wrote about how she love the 50's jacket seen below. I cant read Japanese, but in the intro, there was mention of 50's and this was the picture and what captured my attention to buy the book. I am in love with the pattern but have not find the courage to sew a jacket as of now.
Another simple skirt design I love, I love the cardigan even more but there was not pattern.
Whether one understand Japanese or not, it does not matter. The patterns are fairly easy to follow and their instructions are very clear. However, some comes with basic pattern and no step by step picture instructions, so one has to figure out how to sew them. Maytbe for someone sewing for the first time, they may find the instructions a bit confusing but if you have a little experience, you will sail through this.
If only I have more time.
