Japanese Buddhist monk Ryusho Soeda poses for a photograph during an interview with Reuters at his temple in Koyasan in Koya, Wakayama prefecture, June 25, 2013. Ryusho Soeda, 66, has taken on a job for which his career as a Buddhist priest never prepared him: forensic accounting. Soeda's temple is the 1,200-year-old Koyasan, a World Heritage site deep in the mountains of western Japan and long prized as a haven for quiet contemplation. But in recent months monks here have been debating a very worldly question: How did a complex bet on the yen go so horribly wrong? Picture taken June 25, 2013.
