Courtesy of another beautiful, dedicated tumblr fan (smallhirodork @ tumblr), you can download the entire Hiro's Journal book, which details Hiro's point of view of all the events of the film. Needless to say, major spoilers.
A compilation of quite a few non-spoiler, no-context quotes spoken by Tadashi Hamada. Quotes were obtained from the Junior Novelization. Huge thanks to hxneylemon @ tumblr for posting all of these!
