Discover Japan’s Ogasawara Islands: Things to Do and Much More

  • The Ogasawara Islands (小笠原諸島) are a group of 30 islands located about a thousand kilometers away from Tokyo (東京) to the south of Izu Islands (伊豆諸島). These are also known as Bonin Islands (ボニン諸島) which translates to “uninhabited islands” in Japanese. The archipelago is a UNESCO World Heritage Site and is mostly referred to as “the Galapagos of the East” due to its disconnection from the continent.

    Ogasawara Islands

    Although initially uninhabited, the islands were later discovered by the European and Japanese in the late 16th and 17th centuries, respectively. It is claimed that the Spanish explorer, Bernardo de la Torre, has discovered Ogasawara around 1543 A.D. The islands was under US occupation for a while and the inhabitants had a unique creole language.

    Chichi-jima (父島) and Haha-jima (母島) are the two main inhabited islands in the archipelago. These two are referred to as “Father Island” and “Mother Island,” respectively, and both of which come under the Ogasawara Village of Ogasawara (小笠原村) Subprefecture of Tokyo.

    Chichi-jima is the largest island that acts as an entrance to the archipelago. Formed due to underwater volcanic activity, it is rare to see flatland on any of the islands of Ogasawara. Chichi-jima is filled with short mountains and dense scrub forests with a total population of around 2,000 as per 2009 census. The highest mountain is Mt. Chuo (中央山) with an altitude of 319 meters.

    With beautiful, pristine beaches, clear turquoise waters, and coastal vegetation, Chichi-jima is truly a tropical paradise. The climate is mostly dry with warm temperatures all year round. There is an observatory called the Nagasaki Observatory (長崎展望台) located on a cliff to observe the skies. One can find remains of World War II such as shipwrecks and aircraft belonging to the US Army on beaches such as Sakaiura (境浦) and Kopepe (コペペ). These beaches are also great spots for snorkeling. Scuba diving, snorkeling, and dolphin watching are some of the recreational activities you can do in Chichi-jima.

    If you are looking for stores or bars to stroll around in the evening, you can head to the downtown area of Omura (大村) District near Futami Port (二見港). There are a couple of inns in the area for you to stay at.

    There is a variety of marine life you could encounter during your activities in Chichi-jima. You can also see the rarest lava pillows on beaches like Kominato (小港) on the island.

    Haha-jima, the second largest island, has a population of 450 as per 2009 census. It is located 50 kilometers to the south of Chichi-jima. There are a few unique species of snails and birds such as the Bonin white-eye on Haha-jima. You cannot find these animals anywhere outside of Ogasawara. It is said that there used to more number of unique birds and fish wandering but were put on extinction due to increasing human interaction.

    The highest mountain on Haha-jima is Mt. Chibusa (乳房山) which has an altitude of 463 meters. There is also another mountain called Mt. Kofuji (小富士) which is termed as “Japan’s Southernmost Local Fuji,” from whose top you can get to see the sunrise and sunset before entire Japan does. During sunsets, you can see an interesting phenomenon of green flashes from the sun as it goes down the horizon.

    There is a village called the Oki Village (沖村) on the southern part of Haha-jima whose residents make a living out of commercial fishing. The village is also famous for its unique blend of rum. Moreover, there are beautiful coral reefs on the southern tip of the island called the Minamizaki (南崎) peninsula.

    The whole island was settled by Europeans before becoming a part of Japan. It was also severely destroyed during the World War.

    There are a few small uninhabited islands that form as part of the Hahajima-retto (母島列島) or Hahajima Cluster such as Muko-jima (向島), Ane-jima (姉島), Imoto-jima (妹島), and Mei-jima (姪島).

    There are a few more islands that come under Ogasawara which are called Volcano Islands or Kazan-retto (火山列島). Although geographically a part of Nanpo Islands (南方諸島), the surrounding “Volcano Islands” are administratively grouped under Ogasawara Municipality. The Volcano Islands are a group of 3 active volcanoes that lie to the south with a population of approximately 380. The Japan Self-Defense Force operate from an air base here.

    Flora and Fauna

    Due to its long distance from the mainland, the Ogasawara archipelago has some unique species alive. The islands are home to more than 140 species of flora and fauna. There used to be many other unique species that are native to these islands but went into extinction.

    There are some legends surrounding unique species that are spotted here. For example, the giant squid that can grow up to 13 meters has been first photographed near Chichi-jima. It is impossible to find these giant creatures as they live at a depth of nearly 300 to 1000 meters under sea level.

    Bonin petrel

    There are a few unique bats that are endemic to the islands called the Sturdee’s pipistrelle that were recorded only once in 1915, and the Bonin flying fox which is an endemic fruit bat. Some of the birds that are native to the islands are the Bonin petrel, the Bonin grosbeak, and the Japanese wood pigeon. These are either critically endangered or completely extinct due to the loss of their habitat. There are also different varieties of snails that are endemic to the islands which have been discovered.

    Coming to the flora side, it is said that nearly 43 percent of the total number of species of plants one can see in Ogasawara are endemic to the place. The archipelago is home for some of the outliers of plant species that are seen elsewhere in the world. Because of long isolation, the plants here have developed some unique characteristics.

    Green sea turtle

    When it come to marine life, Ogasawara remains a natural habitat for species such as green sea turtles. These green sea turtles are present in the Pacific Ocean, in the warm tropical and subtropical waters. However, they are endangered due to increased human activity. The locals of Ogasawara used to hunt them for a source of protein. Now, the government has taken measures by curbing illegal fishing which is leading to an increase in their number again. There are also different varieties of corals and tropical fish that can be seen in the waters of this isolated archipelago.

    Because of these interesting species of flora and fauna that have exhibited unique evolutionary characteristics, Ogasawara is proudly known as “the Galapagos of Japan” and “the Galapagos of the Orient.”

    Things To Do

    Ogasawara-mura or Ogasawara Village is an administrative subdivision that encompasses all the major islands of the Ogasawara archipelago. To reach the northernmost inhabited island of Chichi-jima, one has to take a ferry from Takeshiba (竹芝), Tokyo. It usually takes around 25.5 hours to reach the Futami Port of Chichi-jima from Tokyo.

    To see different places in either Chichi-jima or Haha-jima, one has to take a bus or rent a bike. There is a regular ferry service from Chichi-jima to Haha-jima which usually takes around 2 hours on a clear day.

    Here are a few things to do when you are in Ogasawara:
