The Ogasawara Islands, also known as the Bonin Islands, are a remote archipelago located approximately 1,000 kilometers south of Tokyo, Japan. This chain of over 30 subtropical islands is situated in the Pacific Ocean and is divided into three main groups: Chichijima, Hahajima, and the Mukojima islands. The islands boast dramatic landscapes characterized by rugged coastlines, lush vegetation, and pristine beaches.

A unique feature of the Ogasawara Islands is their volcanic origin, contributing to a variety of underwater topographies that make for extraordinary diving experiences. The islands’ isolation has also resulted in a high degree of endemism, with many species found nowhere else on earth.

How to Get There

• Logistical Tips:
  • Book in Advance: Given the limited frequency of the ferry service, it is advisable to book tickets well in advance, particularly during peak travel seasons.
  • Prepare for Seasickness: The ferry ride can be rough, and travelers prone to seasickness should take precautions with medication or other remedies.
  • Plan for Limited Services: The remote nature of the islands means that services such as Internet and phone connectivity may be limited. It is wise to download necessary maps and information beforehand.
