Nishinoshima Island in the Ogasawara Islands had erupted since 2013, and the island was
broadly covered with lava, creating new land. The island lies in an isolated spot in the Pacific
OceanNPDZD\IURPWKHQHDUHVWODQGWKHUHIRUHLWLVRQHRIWKHEHVWSODFHVLQWKHZRUOGto observe the primary succession of an ecosystem on an oceanic island without
anthropogenic effects. In September 2019, the first comprehensive academic survey was
conducted to record the current state of the island’s nature. Using a biological and geologicalapproach, the aim was to investigate the changes that had occurred, such as the process offormation of volcanic islands, the impact on the biota due to the eruption, and the situation at
the start of primary succession.

This survey was conducted in cooperation with the Ministry of the Environment, theUniversity of Tokyo, and the Japan Broadcasting Corporation. A total of 22 members,
including experts in ornithology, entomology, soil zoology, botany, marine biology, geology
and volcanology, and support squads, landed on September 3-5. During the survey, quarantine
measures were implemented to prevent the invasion of alien organisms to Nishinoshima andminimize the human impact of the survey. Considerable attention was given to safety
management during landing operations and minimizing risks from volcanic activity.
