Crown Prince Naruhito is planning to visit three Southeast Asian countries from late June, an Imperial Household Agency source said Friday.

Arrangements are being made for the Crown Prince to go to Thailand, Laos and Cambodia for about a week, during which he is likely to meet with dignitaries from each country, the source said.

Meanwhile, the agency announced Friday that the Crown Prince's younger brother, Prince Akishino, and his wife, Princess Kiko, will make an official trip to Uganda in mid-June.
