She is the first member of Japan's royal family to visit Russia since 1916.
"It just happened to be that I am the first member of the Imperial family to visit in 102 years, but to come here is a great honour for me," Princess Takamado told reporters after visiting St Feodor Ushakov Cathedral in Saransk on Wednesday.
Relations between Moscow and Tokyo are strained over the roll-out of a U.S. missile system and Moscow's move this year to deploy warplanes to a group of disputed islands north of Japan.
"As I already said, this year we celebrate the year of Japan in Russia and the year of Russia in Japan," she said of a cultural exchange programme between the countries, according to the official translation of her comments in Japanese.
"And I hope that many Russians will get to know Japanese culture and will learn more about Japan. And Japanese people will also have chance to learn more about Russia.
"And I hope that this friendly approach will continue and will strengthen further."
The princess, the widow of a cousin of Emperor Akihito, has no plans to meet Russian dignitaries, according to Japanese news agency Kyodo.
"Colombia is a very strong team. And after the third minute of the game they had to play with 10 players only on the pitch," Princess Takamado said.
"But they reacted very well and kept Japanese players very tight."
The princess will also visit the Russian city of Ekaterinburg to watch the Blue Samurai take on Senegal on Sunday.
