There are some great free Japanese knitting patterns but if you don't know Japanese then it can be hard to find them or to know what the links to the pages say.
Luckily, I've been able to find some sites through Ravelry's Japanese Knitting and Crochet group and Yahoo's Knitting In Japan group. If you are anywhere interested in Japanese knitting and crochet patterns, I highly recommend both groups. The people on the lists are so nice and there are some fluent Japanese speakers that are often willing to help with translations of parts of patterns.
One of the best places to find free Japanese knitting patterns and Japanese crochet patterns is on the Pierott (Gosyo Co.,Ltd) website. The first time I got on the site, I was a little overwhelmed because I didn't know where to click for the patterns.
I use the Google search bar with the Translate feature turned on to help me read the words on the pages that aren't images.
Here's a list of some of the them:
Fall and Winter Patterns, Volume 1:
Fall and Winter Patterns, Volume 2
Fall and Winter Patterns, Volume 3
Bags (knit and crochet):
Caps, Mittens, Scarves (knit and crochet)
Tops (knit and crochet)
Tops, vests, ponchos (mostly knit)
Kids and baby (knit and crochet)
Shawls and stoles, with tops and a couple of suits (mostly
Short sleeve tops (knit and crochet)
Shawls, Scarves (knit and crochet)
Just click on an image and you'll be taken to the information page about the pattern. There are usually 4 sections next to the garment patterns.
The first section is the yarn information. The second section is the needle section (Be careful! These are Japanese needle sizes, not US or metric. Use the Basics of Japanese Knitting page for a conversion of needle sizes). The third section is additional items needed. And the fourth section has the link to the PDF pattern.
Unfortunately, the PDFs don't have pictures of the items. So I just print out the information page and the PDF and keep them together.
I could spend hours looking at all the patterns and I have quite a few I'd love to knit. Hope you have fun looking through them too!
