iWork Pages Vertical Text Help

Since replying to old posts is my hobby:

I don't believe this is possible in Pages. Apple is generally slow to get anything Japanese done right, presumably reflecting a lack of quality Japanese employees at Apple. They get conversion wrong. They get text input wrong, like you're being frustrated with. They get handwriting recognition for Chinese right, it looks like, but then for some crazy reason don't allow Japanese input to use that technology for kanji. Basically, Apple doesn't understand the Japanese user's needs, which is a major factor in why Japanese are slow to switch.
