I just finished chart A (there are 4 charts) and the easiest part of the shawl - because it starts with 7 stitches and grows on either side of a center stitch ending with 367 stitches. So far so good.
I looked up the name "Sakura" and it means cherry blossom in Japanese. I think it is looking more like peacock feathers. Either way, the pattern is very pretty.
