Norwegian Jade: 15-Night Transpacific from Tokyo

Yokohama is Japan's primary ocean cruise hub and the second-largest city in the country, about 30 kilometers south of central Tokyo. Although Tokyo is far more famous, its central harbor has no suitable cruise terminal for large ships.

Icy Strait Point is a privately developed cruise destination adjacent to Hoonah, a Tlingit village of about 800 people on the northern shore of Chichagof Island. Unlike most Alaska ports, this is a purpose-built cruise facility operated by Huna Totem Corporation, the local Tlingit Alaska Native corporation, meaning tourism revenue stays in the indigenous community.

Juneau cruise port is the capital of Alaska and one of the main stops on Inside Passage itineraries. The town sits on a thin strip of coast at the foot of Mount Roberts and Mount Juneau, backed by the 1,500-square-mile Juneau Icefield and surrounded by the Tongass National Forest.

Skagway cruise port is the northernmost major stop on most Alaska Inside Passage cruises and one of the best-preserved gold rush towns in the world. The town sits at the head of the Lynn Canal fjord, wedged between the Coast Mountains and the Taiya Inlet, with a population of about 1,000 permanent residents that balloons with each cruise ship arrival.

Ketchikan cruise port is the first major stop on most Alaska Inside Passage itineraries coming up from Seattle or Vancouver. The town sits on Revillagigedo Island in Alaska's southernmost panhandle, wedged between the ocean and steep forested mountains.
