Tokyo (東京, Tōkyō), Japan's vibrant capital and the world's most populous city, is a fascinating blend of history and modernity. Once known as Edo, it became the political heart of Japan in the early 17th century under Tokugawa Ieyasu. After the Meiji Restoration in 1868, it was renamed Tokyo, meaning "Eastern Capital." Although it faced devastation during the Great Kanto Earthquake and World War II air raids, Tokyo has emerged as a dynamic metropolis, comprising 23 central wards and beautiful islands like Izu and Ogasawara. Today, Tokyo captivates visitors with its endless options for shopping, dining, and entertainment. Explore historic districts like <a href="https://www.japantripideas.com/[language]/attraction/427/asakusa" title="Asakusa Tokyo District">Asakusa</a>, filled with temples and museums, and discover lush green spaces nestled within the bustling city.

Kyoto (京都, Kyōto) was Japan's capital and the emperor's residence from 794 to 1868. Today, it is a vibrant city with 1.5 million inhabitants, blending its historical significance with a modern atmosphere. Despite enduring wars and fires over the centuries, Kyoto was spared from destruction during World War II due to its historical importance. As a result, numerous temples, shrines, and other priceless cultural sites remain, making it a key destination for those interested in Japan's rich heritage.

Osaka (大阪, Ōsaka), Japan's second-largest metropolitan area after Tokyo, has been the Kansai region's economic hub for centuries. Historically known as Naniwa, it was Japan's first capital before the Nara Period, when the capital shifted with each new emperor. In the 16th century, Toyotomi Hideyoshi built Osaka Castle, and the city was poised to become Japan's political center. However, after Hideyoshi's death, Tokugawa Ieyasu ended the Toyotomi lineage and moved the capital to Edo (now Tokyo), changing the course of history.

Nara (奈良), Japan's first permanent capital established in 710, is a treasure trove of history and culture. Once a powerful city that saw emperors come and go, Nara was eventually overshadowed by the rising influence of its Buddhist monasteries, leading to the capital's relocation to Nagaoka in 784 and later to Kyoto. Today, Nara is less than an hour's journey from both Kyoto and Osaka, making it an easily accessible destination for travelers. Visitors to Nara can immerse themselves in its rich heritage, exploring ancient temples and shrines that are among the oldest and largest in Japan. From the stunning Todai-ji Temple, home to a giant Buddha statue, to the serene Nara Park, where friendly deer roam freely, every corner of Nara offers a glimpse into Japan's storied past.
