India Prime Minister Manmohan Singh is beginning a five-day, two nation visit to east Asia with a stop in Tokyo.
Singh is expected to spend three days in Japan, meeting with officials to discuss Indian-Japanese cooperation in politics, security, and the energy sectors. Talks with his counterpart, Shinzo Abe, are expected to include cooperation on nuclear energy, a subject that has stalled since Japan's nuclear accident at Fukushima in 2011.
Singh has told reporters that he expects nuclear safety to be part of the discussion.
The two prime ministers are also expected to discuss military ties, and increasing trade cooperation.
On Wednesday, Singh is expected to call on Japan's Emperor Akihito and Empress Michiko.
May 30 and 31, Singh is set to make a stop in Bangkok to meet with Thai Prime Minister Yingluck Shinawatra. Subjects on the agenda include cooperation on infrastructure projects, defense, science and technology and education.
