ageHa (also as 'AGH') is a nightclub and event space in Shin-Kiba, Kōtō, Tokyo, Japan. The club opened in December, 2003. The venue is also known as Studio Coast. The word Ageha is Japanese for 'Swallowtail butterfly'. The club's name has recently been presented in the 3-letter-version 'AGH' in capital letters, for instance on the official staff shirts. If the three letters are pronounced separately in German, they are pronounced as "ah-geh-ha", similar to the Japanese pronunciation of the club's name.
