A healthy appetite is all you'll need to take to the Manpaku festival at the Green Culture Zone of the Showa Kinen Park (Tachikawa Park) in Tachikawa, western Tokyo. "Manpaku" is a play on the words "manpuku" ("enjoy food to the fullest) and "mankitsu hakurankai," which roughly translates to "enjoying to the fullest exhibition," so expect to leave fully satiated.
