While we have no other details at this time, via their official Facebook page, the Australian anime publisher Madman Entertainment confirmed that they were aiming to release Nichijou – My Ordinary Life during March 2013. As this has not yet been formally announced expect this to possibly change in the coming weeks.
Nichijou’s acquisition was announced by the company during the Sydney Supanova 2011. Given events that have occurred with Bandai Entertainment, the previous North American licensor for the show over the year it is likely to be a subtitled release on DVD.
While its availability will possibly change once a physical release is announced, if you reside in Australia you can check out Episodes 1 – 26 via the Madman Screening Room HERE.
