Prime Minister Fumio Kishida is planning to visit Brussels in mid-July for a regular summit with the leaders of the European Union.
Kishida is expected to meet with European Council President Charles Michel and European Commission President Ursula von der Leyen on July 13.
The Japanese leader is considering attending the July 11-12 NATO summit in Vilnius, the capital of Lithuania.
The previous summit between Japan and the EU took place in Tokyo in May last year.
At the possible summit next month, Kishida is expected to reaffirm his country's position that the security of Europe and that of the Indo-Pacific region are inseparable.
The Japanese and EU leaders are expected to confirm their unity against Russia's continued invasion of Ukraine and to seek consensus on China's moves.
They will also discuss the possible lifting of import restrictions on Japanese food products that the EU introduced after the 2011 triple reactor meltdown at Tokyo Electric Power Company Holdings Inc.'s Fukushima No. 1 nuclear power plant in northeastern Japan.
Elsewhere on the summit agenda are likely to be ways to deepen the two sides' cooperation in the digital field, such as creating international rules for the use of generative artificial intelligence.
