Abstract
Hadron photoproduction reactions are complementarily studied at SPring-8/LEPS and ELPH, Tohoku University. Their recent results on hadron structure and interaction are summarized in the present article. On the pentaquark candidate Θ+, a clear peak structure is seen in new exclusive analyses using increased statistics data of the γ d→K+K−X reaction. A new project LEPS2 has started at SPring-8 in conjunction with LEPS and ELPH. Recent progress is discussed including a new photon detector system BGO-EGG, which is under construction at ELPH. LEPS2 beam commissioning will start from the end of FY2012.
