Tokyo: ime Minister Manmohan Singh left here today for home after four-day visit during which he held talks with his Japanese counterpart Shinzo Abe on various issues including India's growing need for civilian nuclear energy.

During the talks Japan agreed to engage in discussions with India on civilian nuclear cooperation under "appropriate" international safeguards in a clear indication that it may come round to backing the Indo-US nuclear deal.

Japan stopped short of any direct support to the landmark Indo-US deal but said that international civilian nuclear energy cooperation should be enhanced through "constructive approches" under appropriate International Atomic Energy Agency (IAEA) safeguards.

The two countries also decided to estsblish a strategic and global partnership and signed nine agreements covering a range of areas including political, economic and defence sectors.
