Singh will visit Japan from May 27-30 for talks with his Japanese counterpart Shinzo Abe, the Japanese Foreign Ministry said today.
The two leaders plan to hold a summit on May 29, Kyodo news agency quoted a Japanese government source as saying.
They are expected to discuss the civilian nuclear cooperation agreement between the two countries and Japan's possible export of nuclear power technologies to India, it said.
Negotiations for the accord have stalled since Japan was struck by a powerful earthquake in March 2011 and the subsequent nuclear disaster at the Fukushima Daiichi nuclear power plant northeast of Tokyo.
Singh will also meet with Emperor Akihito and Empress Michiko during the trip, his first since October 2010 for a summit with then Prime Minister Naoto Kan.
"As India is a South Asian power that shares with us values such as freedom, democracy, human rights and rule of law, we aim to expand the partnership by discussing a wide range of issues including politics and the economy," a government official told reporters.
Singh had postponed a trip to Tokyo in November last year after a general election was called in Japan.
