The Ogasawara Islands are one of the breeding grounds in the North Pacific, consisting of three groups.
As it is said, "Whales are creatures at the top of the food chain," their ecological status and role as higher animals in the marine ecosystem are significant. The lower organisms that serve as food for whales show considerable annual variability, and the composition of whale diets responds sensitively to these changes. Additionally, due to the characteristic of higher animals to accumulate pollutants, whales are particularly susceptible to the effects of heavy metals such as mercury and cadmium. Studying whales not only helps to elucidate their ecology but also provides clues to understand changes in marine ecosystems and the realities of marine pollution associated with climate change.

Applications/Examples of results
This is a project in which researchers from six countries (the United States, Canada, Mexico, Russia, Japan, and the Philippines) are collaboratively working to elucidate the ecology of humpback whales in the North Pacific. Researchers from various countries are cooperating beyond the framework of whaling and anti-whaling, conducting ecological surveys based on scientific knowledge, which are planned to take place over three years starting in 2003. The Ogasawara Marine Center serves as the coordinator for the Asian waters (Ogasawara, Okinawa, Philippines) and is not only conducting substantial surveys in the Ogasawara waters but also hosting international symposiums.

Company information
This organization was established in August 1999 with the aim of conserving marine life in the Asian region and the surrounding marine environment. Initially, it functioned solely as the domestic liaison for Yayasan Penyu Laut Indonesia - Pusat Penelitian Penyu Indonesia (Indonesian Sea Turtle Research Center), a local NGO in Indonesia. However, in July 2002, it received certification as a non-profit organization (NPO) and, with its incorporation, began substantial activities in the field. The organization is referred to by the abbreviated name ELNA, which stands for Everlasting Nature of Asia.
