1. She'll have to get two Temporary Visitor's (aka tourist) visa statuses.
2. To my knowledge there is no transit visa in Japan, instead they usually get the standard "Temporary Visitors" status (like a regular tourist would).
3. For the second visit for 10 hours she might be able to get a "Shore Pass" granted on site, however this is at the discretion of the Immigration Officer.
