Princess Kako, a niece of Emperor Naruhito, has attended a dinner in Budapest celebrating the 150th anniversary of diplomatic relations between Japan and Hungary.
Princess Kako is the second daughter of Crown Prince Akishino, the Emperor's younger brother.
The princess talked with guests from various fields who have contributed to the promotion of bilateral ties.
She said in her speech she hopes that the friendship between the two countries will continue to be cherished.
Earlier on Saturday, the princess visited a national horse farm in Babolna in the western part of the country.
The estate was established in the late 18th century and has bred carriage horses for nobles as well as military horses.
After she received a lecture about the history of the farm, she accompanied the agriculture minister for a ride in a carriage drawn by five horses.
