British & Irish Lions warmed up for their South African tour with a four-try win over Japan marred by an injury to captain Alun Wyn Jones.
The Welsh prop went off injured after only seven minutes at Murrayfield with a potentially serious shoulder injury.
Josh Adams, Duhan van der Merwe and Robbie Henshaw all touched down within the opening 23 minutes.
Tadhg Beirne added another try after the break before Kazuki Himeno replied as Japan showed second-half resilience.
Warren Gatland's squad now head for South Africa, where they will begin their tour against Emirates Lions at Ellis Park, Johannesburg, next Saturday.
But, before then, they face a nervous wait for news of Jones and fellow Welsh forward Justin Tipuric, who was also withdrawn through injury early in Edinburgh.
