Jappon is an island country in the World of Hunter × Hunter. Being the home country of sushi, ninja, and haiku, it is the fictional equivalent of real-life Japan. Hanzo, Basho, and Nobunaga Hazama are from this country.
- Every Japponese character in the series is named after a famous person in Japanese history.
- Jappon is a portmanteau of the words "Japan" and "Nippon," the formal reading of the kanji "日本" meaning Japan.
- Jappon's real-life counterpart Japan is the only landmark on the real world map that has not been rotated or flipped to produce its counterpart on Hunter × Hunter's world map.
