I thought I had seen the vast majority of most Studio Ghibli projects, but it seems I missed out on one: Omohide Poro Poro, or Only Yesterday as it is known in English. The film has been released in the UK and Australia, but still has not been picked up by Disney for a release in the US. It tells the story of a woman named Taeko as she makes a journey into the countryside and remembers her past. Sounds like perfect Ghibli material -- I can see myself tearing up already.
Anyway, the film has been adapted into a musical which will run at Tokyo's Ginga Gekijō theater from April 16 to 29, 2011. This marks the first Ghibli film to be adapted into any sort of stage production. After it finishes its run at this location, it will move to Semboku City in the northern prefecture of Akita from May 8, 2011 to January 3, 2012 and then it will go on a national tour. I wish I could go see it! I bet it's wonderful.
