Appare Jipangu! (Amazing Japan!) is pure comedy, Watase did this series as a light hearted manga to get away from the heavy drama that takes over Ayashi no Ceres, which she was doing at the same time.
Appare Jipangu follows Yusura, an orphan who when her adoptive parents found her she had with her a Kongomaru, which when she grows up will be used to fight sadness by becoming a Hikeshiya .... charging a small fee for her work, of course. With her sidekick, Minekichi; and love interest, blind as a bat, Samon, and a whole bunch of other rowdy characters, will Yusura ever find her birth parents? Or figure out that she's fallen in love?
Tankoubon, or better known as Graphic Novels, compile manga chapters into book format. Below you can find release date information as well as ISBN numbers to help you track down a copy of your own. Because of the long time gap between the release of volume two and volume three, it was decided to re-release the first two volumes. Appare Jipangu has not been released in English.
Bunko, or pocket editions, are smaller versions of the tankoubon. They compress the series into a smaller amount of volumes, to make it easier for new readers to collect. Bunko have no extras like the authors comments, or extra illustrations that the tankoubon have. Its just the manga, nothing more, nothing less.
