Japan sent diplomatic envoys to the Chinese court between 630 and 894, during the Tang Dynasty. Now, a real-sized replica of the boat carrying Japan's consulates is berthed at Shiliupu Pier in Shanghai. It will sail to Expo Park on June 12 to celebrate the Japan Pavilion.

On that day, the boat will sail on Huangpu River from 3 p.m. until 5 p.m. with Ken Watanabe, a renowned Japanese actor, filling in as an ambassador to China. A number of Japanese celebrities including singer Maaya Sakamoto will also be aboard the boat.

In the Japan Pavilion, there is a display of the history of Imperial embassies in China to showcase the cultural export from China to Japan 1,000 years ago. The boat will also bring about a banquet held by Yang Guifei, the favorite concubine of Emperor Xuanzong of Tang.

The boat started its journey on May 8 from Osaka, the port from where Japan's diplomatic envoys traveled to China. It followed the original sea route, which passed by Kure, Hakata, Nagasaki and Goto Islands.

The engine-powered boat is 33.6 meters long, 9.2 meters wide, and features classic Japanese architecture. Equipped with functional sails and masts allowing manual operation, it is made of steel and wood. The sails require eight people to pull from different directions. Several traditional cabins house paddles, anchors and a helm. The captain's room is small with barred windows. The boat's red phoenix-shaped stem and red and white wooden hull attract many tourists in Shanghai.
