The tourism industry in Hawaii is anticipating a boost from a stretch of Japanese holidays known as “Golden Week” that has been extended this year.

The Honolulu Star-Advertiser reports the four national holidays typically held over seven days are a popular time for Japanese tourists to visit Hawaii.

This year the holiday period has been extended to 10 days between April 27 and May 6 due to a change in the ruling family.

Emperor Akihito is scheduled to abdicate the throne on April 30 in favor of Crown Prince Naruhito, who will replace his father on May 1.

The CEO of Hawaii’s largest destination management organization says he expects nearly 40 percent more Golden Week visitors this year than last with about 8,700 travelers already booking trips.
