There is a good Japanese image board for pictures of seiyuus. In fact it even has a second section. Lots of good photos show up. The only problem is that the custom of the board is not to say who the photos are of. Like a lot of Japanese message-board discussion, it is only for the cognoscenti.
There's no problem with these recent magazine photos of Inoue Marina from the board: her name is written on the pages of the feature on Highschool of the Dead, in which she stars as Rei. These are the most provocative pics of her I've seen. Click photos to enlarge.
I've never been a huge fan of her work. But perhaps it's just that she doesn't play in animes, or play characters, that I like. However, I do find myself admiring her evident strength and ability. She went to girls' schools up until college, and is supposedly a graduate of a university attended by the upper classes.
She apparently got into seiyuu work when she started college. She realized that in a co-ed setting she could not play the male roles she always did in the drama club at school, so she became one of two thousand entrants in a Sony seiyuu competition in 2003, when she was 18...and won the Grand Prize.
I also came across this old photo of her in her pre-seiyuu cosplaying days (cosplaying a baby). It was in a 2channel anti-Marina thread, and was held up as an example of what a bad person she is, since she used to be cosplayer and work on doujins in high school, and could have been described as a fujoshi. Those all seem like good things, to me.
Most of the criticism is of her supposedly being too proud of her good looks, ability, and success, and too hard on people who don't have them. Maybe. But sometimes it's hard for very capable people to accept anything less than their own standards, and I'm sometimes willing to accept their pride for the sake of everything else they bring to the table.
There are also unsupported (in my opinion) rumors that she and Nakamura Yuuichi are living together. I wouldn't hold that against her, either.
Other people say he is going with Sugita Tomokazu, and his friendship with Marina is a smokescreen. Yadda, yadda.
