  Unryu Suganuma (菅沼 雲龍, Suganuma Unryu, born 1964) is a Japanese academic interested in international relations, especially China and Japan.
  
  ## Early life
  
  Suganuma grew up in China and in Japan. He was awarded a master's degree in Chinese Studies at St. John's University in 1992 and he earned a master's degree in International Relations at Syracuse University in 1993. His PhD was conferred by the Maxwell School of Citizenship and Public Affairs in 1996.
  
  ## Career
  
  Suganuma is Associate Professor of Geography at Oberlin University in Tokyo. His research interests focus on the historical justification of territorial space, investigating the historical argument of territorial disputes or irredentism which is conventionally found in debates claiming "new territory" by many states. His major thesis is that people living in different places during different periods have different concepts of territorial space.
  
  Suganuma is known for arguing "if there is a flash point to ignite a third Sino-Japanese War, it will be the ownership of the Diaoyu Islands in the East China Sea".
