Bhutan's King Jigme Khesar Namgyel Wangchuck and his wife, Queen Jetsun Pema, arrived in Tokyo Tuesday, kicking-off their six-day visit to Japan.

The newlywed royal couple of the Himalayan kingdom made their visit truly official as the duo were dressed in the Bhutanese national dress. Bhutan has a dress code for its citizens, who have to wear it in public every day. The national dress code, known as Driglam Namzha, was introduced in the 17th century to give the Bhutanese a distinct identity.

King Wangchuck, 31, participated in the greeting ceremony in Tokyo in the traditional gho, a knee-length robe for men. A gho is tied at the waist by a cloth belt known as the kera. Wangchuck, often called Prince Charming for his Elvis Presley looks, wore the traditional dress with a kabney, a silk scarf usually worn with gho, wrapped around the left shoulder.

The 21-year-old Queen looked elegantly dressed in a vibrant yellow attire during her official trip to Japan. She sported a long-sleeved, short silk jacket, called toego, over an ankle-length hand-woven kira (kind of wrap around long rectangular skirt) bound around the waist. Kira and toego form the national costume for women in Bhutan.

Bhutan's fifth Dragon King Jigme Khesar Namgyel Wangchuck married a commoner, Jetsun Pema, in a royal ceremony at Bhutan's ancient capital, Punakha, on Oct. 13. The couple honeymooned in India in late October.

The Bhutanese royal couple, often dubbed as the Will and Kate of the Himalayas, was welcomed by Japan's Crown Prince Naruhito upon their arrival in Tokyo. They also met Japan's Prime Minister Yoshihiko Noda and his wife Hitomi.

The couple is Japan’s first state guest since the country was hit by the March 11 earthquake that triggered a massive tsunami. The royal couple will also visit places outside the no-go zone around the Fukushima Daiichi nuclear power plant, which was devastated by the tsunami, local media reported.
