Given the question: Information: - Geology. The Oki Islands are volcanic in origin, and are the exposed eroded summits of two massive stratovolcanoes dating approximately 500 million years ago to the Tertiary and Quaternary periods. The oldest rocks in Japan have been found on the Oki Islands. - , originally , was a Japanese legendary prince of the Yamato dynasty, son of Emperor Keik, who is traditionally counted as the 12th Emperor of Japan.

The total area is 389.53km. - The Sea of Japan (see below for other names) is a marginal sea between the Japanese archipelago, Sakhalin, and the Asian mainland. The Japanese archipelago separates the sea from the Pacific Ocean. It is bordered by Japan, North Korea, Russia and South Korea. Like the Mediterranean Sea, it has almost no tides due to its nearly complete enclosure from the Pacific Ocean. This isolation also reflects in the fauna species and in the water salinity, which is lower than in the ocean. The sea has no large islands, bays or capes. Its water balance is mostly determined by the inflow and outflow through the straits connecting it to the neighboring seas and Pacific Ocean. Few rivers discharge into the sea and their total contribution to the water exchange is within 1%. - History.

The current Japanese orthography for Kumamoto literally means "bear root/origin", or "origin of the bear". - The is an Iron Age era in the history of Japan traditionally dated 300BCE to 300 CE. It is named after the neighborhood of Tokyo where archaeologists first uncovered artifacts and features from that era. Distinguishing characteristics of the Yayoi period include the appearance of new Yayoi pottery styles and the start of an intensive rice agriculture in paddy fields. A hierarchical social class structure dates from this period. Techniques in metallurgy based on the use of bronze and iron were also introduced to Japan in this period. - India, officially the Republic of India ("Bhrat Gaarjya"), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country (with over 1.2 billion people), and the most populous democracy in the world. It is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the northeast; and Myanmar (Burma) and Bangladesh to the east.

Its capital is New Delhi; other metropolises include Mumbai, Kolkata, Chennai, Bangalore, Hyderabad and Ahmedabad. - Asia is Earth's largest and most populous continent, located primarily in the eastern and northern hemispheres and sharing the continental landmass of Eurasia with the continent of Europe. Asia covers an area of , about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Asia is notable for not only its overall large size and population, but also dense and large settlements as well as vast barely populated regions within the continent of 4.4 billion people. - The Oki Islands in the Sea of Japan are also part of Shimane Prefecture, which also claims to have jurisdiction over the South Korea-controlled island of Liancourt Rocks ("Korean: Dokdo(), Japanese: Takeshima()"). - The Emperor of Japan is the head of the Imperial Family and is the ceremonial head of state of Japan's system of constitutional monarchy.

Another frontier , in Kysh , was apparently somewhere north of today 's Kumamoto prefecture . The legend specifically states that there was an eastern land in Honsh '' whose people disobeyed the imperial court '' , against whom Yamato Takeru was sent to fight . That rivalling country may have been located rather close to the Yamato nucleus area itself , or relatively far away . The today Kai province is mentioned as one of the locations where prince Yamato Takeru sojourned in his said military expedition . - Legendary narrative. Keik is regarded by historians as a legendary emperor with little information about him. There is insufficient material available for further verification and study. The reign of Emperor Kinmei ( 571 AD), the 29th emperor, is the first for which contemporary historiography is able to assign verifiable dates; however, the conventionally accepted names and dates of the early emperors were not to be confirmed as "traditional" until the reign of Emperor Kanmu (737806), the 50th sovereign of the Yamato dynasty.
