Highlights of this cruise:

Yokohama
Yokohama and Edo began life as sleepy fishing villages. That changed in the early 17th century after Tokugawa Ieyasu became Shogun. Edo became the center of political power in Japan, a position the city retained even after the restoration of Imperial rule in 1866.

Contemporary Tokyo may be the most astonishing city on earth. It's a paradoxical mix of ancient tradition and postmodern culture. The Ginza - an international shopping mecca - stands near the serene grounds of the Imperial Palace, and the hyper-speed of 21st century consumerism is mysteriously reconciled with the elegance and serenity of traditional culture. Tokyo provides the traveler with a dizzying experience.

With the Meiji Restoration of 1868, Edo was renamed Tokyo, the "Eastern Capital," to distinguish it from the old imperial capital at Kyoto, the "Western Capital."

Kagoshima
From the 14th century to the Meiji Restoration of 1868, Kagoshima was the chief stronghold of the mighty Shimazu clan. The city lies at the top of the Satsuma Peninsula, a mountainous, geothermal wonderland of hot springs and geysers. The area is also rich in modern Japanese history: Saigo Takamori and the Satsuma samurai were leaders of the Meiji Restoration that toppled the shogun and restored the Emperor to power in 1868. In 1877, dissatisfied with the direction of the new government, Saigo led the Satsuma Rebellion, which ended in his death and the final defeat of the samurai.

The symbol of Kagoshima is Sakura Jima - the volcanic island that sits just offshore. The volcano has erupted over 30 times.

Nagasaki
For most travelers, Nagasaki is a symbol of the horror and the inhumanity of war. An estimated 75,000 people perished in 1945 when the city became the second target of a nuclear attack. Today, Nagasaki's Peace Park and Atomic Bomb Museum draw visitors from around the world.

But this beautiful city on Kyushu offers other sights. Often described as the San Francisco of Japan, the city occupies verdant hills surrounded by a deep-water bay. For three centuries, Nagasaki was Japan's sole window on the world. The city is also celebrated as the setting for Puccini's opera "Madame Butterfly."

Busan
The second largest city in South Korea, Busan is your gateway to a fascinating land whose culture is a unique amalgam of old and new. Modern high-rise towers dwarf ancient Buddhist temples. The city's bustling business district offers a stark contrast to the serene grounds of Yongdusan Park. In short, Busan is a microcosm of South Korea, a nation whose startling economic success often obscures one of Asia's most sophisticated and venerable cultures.

Busan was the scene of bitter fighting during the Korean War. The United Nations Memorial Cemetery marks the final resting place for the troops from 16 nations who gave their lives during the conflict.

Hiroshima
On August 6, 1945, human history was irrevocably altered when the American bomber Enola Gay dropped an atomic bomb on Hiroshima. The bomb was code-named "Little Boy," but its detonation left half the city in ruins and aflame. Today, Hiroshima is a monument not only to the destructive forces harnessed by men but also to the indomitable will of the human spirit to overcome tragedy. At the heart of the city lies Peace Memorial Park and the Atomic Bomb Dome. The gutted walls of the city's old Industry Promotion Hall and the skeletal frame that supported its copper dome, vaporized in the blast, are instantly recognizable symbols of Hiroshima.

Travelers to Hiroshima will discover a more serene note at nearby Miyajima Island. One of the top-three scenic spots of Japan, the island is home to ancient Itsukushima Shrine, a designated National Treasure.
