Crown Prince Akishino said Friday he does not know whether the marriage between his daughter, Princess Mako, and her boyfriend, Kei Komuro, will take place, with the plan still pending following reports that Komuro's family is involved in a financial dispute.

"I have not heard from my daughter about it, so I do not know how things are at this stage and what she thinks about it," said the 53-year-old crown prince, who became heir to the throne with the ascension of his brother, Emperor Naruhito, on May 1.

The crown prince made the remarks at a news conference with his wife, Crown Princess Kiko, ahead of their first official visit to Poland and Finland from Thursday to mark the 100th anniversary of the two countries' establishment of diplomatic ties with Japan.
