OSAKA –

Prince Hisahito on Thursday inspected the Grand Ring, a huge wooden structure that is a symbol of the ongoing World Exposition in the city of Osaka.

The 19-year-old son of Crown Prince Akishino and Crown Princess Kiko looked around the Grand Ring’s architectural structure from underneath. He then made his way to the top of the structure, where he looked down at the entire venue.

Upon hearing that the entire expo venue sprawls across about 155 hectares, the young prince remarked, “That’s larger than the premises of the Imperial Palace (in Tokyo).”

He then toured the Kansai Pavilion, set up by nine prefectures in and around the Kansai region, looking around exhibits on the histories and cultures of the prefectures.

On Wednesday, the prince visited the Japan Pavilion at the expo venue. After receiving an explanation about plastic that is decomposed by microorganisms, he asked, “What will happen eventually after it breaks down?” He also viewed energy-related exhibits.

He said later, “I feel I was able to look at what kind of future Japanese technology will bring.” Prince Hisahito then visited the Belgian Pavilion and viewed its water-themed interior.

It was the first time for the prince to engage in public activities on his own.
