The Carnival Panorama is sailing from its homeport in Long Beach today for an 18-night cruise to Alaska and Japan.

The unique open-jaw itinerary sails to Yokohama, a port near Tokyo, and features six ports of call.

Part of Carnival Cruise Line’s Carnival Journeys concept, the cruise starts with visits to three destinations in Alaska: Ketchikan, Sitka and Icy Strait Point.

Before crossing the Pacific Ocean, the 4,000-passenger vessel is also set to offer scenic cruising at the Endicott Arm Fjord.

Following eight full days at sea, the ship is scheduled to arrive in Asia for the first time, visiting Otaru and Aomori, in Japan.

The voyage is then set to end at Yokohama on September 10, 2024.

Completing five years of service in 2024, the Carnival Panorama is scheduled to enter drydock in Asia before returning to North America.

In addition to routine maintenance and class work, the 135,000-ton ship is expected to receive Carnival’s new livery during the shipyard stay, as well as occasional upgrades to its public areas and cabins.

After the completion of the work, the Carnival Panorama is set to offer an even longer trans-Pacific itinerary.

Sailing in the opposite direction, the 25-night voyage sails from Singapore to Long Beach on Oct. 12, 2024.

The repositioning voyage is highlighted by visits to Ho Chi Minh City in Vietnam, Kota Kinabalu in Malaysia, Manila in the Philippines and Guam in the Mariana Islands.

Before arriving back in California, the Panorama is also scheduled to make its debut in Hawaii with an overnight visit to Honolulu.

On Nov. 5, the ship resumes its regular schedule of cruises to the Mexican Riviera. Sailing year-round from Long Beach, the six- to eight-night itineraries feature visits to Cabo San Lucas, Mazatlán, Puerto Vallarta, Ensenada and La Paz.
