Macron will hold talks with Prime Minister Sanae Takaichi on Wednesday, and "the crisis in the Middle East will be at the heart of discussions", the Elysee said ahead of the trip.

The two leaders will discuss "how we can try to find common solutions", it added.

Japan depends on the Middle East for 95 percent of its oil imports and has had to dip into strategic stockpiles to temper the impact of rising fuel prices since the start of the war.

Economy and finance ministers of G7 countries, which include France and Japan, said on Monday they stood ready to take "all necessary measures" to ensure the stability of the energy market as they tackled the economic consequences of the war.

Wednesday will be Macron's "first full-fledged meeting" with Takaichi, according to a Japanese foreign ministry official, though the two met on the sidelines of the G20 summit in November.

Among expectations for the talks was "continued communication" with a view towards the "calming down of the situation in Iran", the official said.

The two countries are also expected to discuss security and partnerships in the space sector, and intend to sign a roadmap on nuclear power in Japan, the Elysee said.

Macron and his wife Brigitte are due to have lunch with Emperor Naruhito and Empress Masako on Thursday.
