Japanese hook sizes - "steel"

I read a lot of japanese crochet patterns. Many of them are thread weight.

There is this beautiful bolero I would like to make into my size, it would be perfect for classic lolita or mori kei or even himegyaru.

Its absolutely gorgeous but even in the book itself its very complicated, so I'm thinking about making this pattern instead. http://www.ravelry.com/patterns/library/p23-bolero . Its slightly simpler.

I can read a little japanese: hirigana, katakana, and some kanji. MEEEH why would you use kanji in a pattern?? Then only those who are absolutely up to reading level in japanese can read it. The people who make these patterns are usually good about making diagrams. I plan on learning japanese more, but for now, diagrams will do. I guess.

Oftentimes these patterns are one size fits all. At least they are good about making them in a size that is highly adaptable, somewhere in between bust size 32 and bust size 38, a medium for a lot of people.

Japanese patterns use an "#/0" symbol for the size of their hooks and needles. US and UK use "size #" for their hook sizes in patterns. I keep forgetting the japanese to metric to US conversion for the needles. I think I'm going to make a chart in english. Or at least borrow one from the Rakuten site: http://www.rakuten.co.jp/gosyo/438728/672881/

I think hooks that don't have labels are just listed in mm size in the pattern.

If I got some info wrong, do comment and I will try to fix it.
