Steve Sly Japanese Works of Art has dated this piece to the 1890s.
His given name was Sotojiro and he is recorded as a member of the Tokyo Chukinkai (Tokyo Cast Metalworkers' Association) in the second half of the Meiji period.

Provenance: We were fortunate enough to be invited to purchase a retired gentleman's entire Japanese collection in 2014, amongst many fine pieces of Metalwork were his pride and joy , this and another similar Sea Eagle on stand by the same artist , we purchased both birds and soon after we sold them to a regular client in Taiwan,this was during the period when the Chinese market was apparently on fire , last month the dealer in question informed us that his market had now significantly cooled off and that he wished to offer to sell us the birds ,it was not a difficult decision to want these items back, he flew to London with both birds in the hold and we were thrilled to have been reacquainted with them , the transaction left both parties satisfied, and further demonstrated our belief that great quality Japanese works of art will always find a place somewhere in the world market .
The condition is quite superb !
