Listed in the Japanese Biographical Index as a "painter, wood-carver"², a 1926 article in The Studio: An Illustrated Magazine of Fine and Applied Art credits Fukunaga with being a part of the "revival of wood-block printing" going on to say, "A painter of recognised standing, known for his originality in getting certain colour effects in his painting, he had designed a series of prints illustrating the great Tokyo earthquake and fire with a view to making a permanent pictorial record of a number of acts of heroism which were called forth by that awful catastrophe."³ The below print is reproduced in the magazine as an example from the referenced series titled Picture Album of the History of the Taishō Great Earthquake. (Note that the print's margins are not shown on the reproduction.) Each of the four prints (two of which are in this collection), I have seen in the series use the artist's seal reading 晴帆 (Seihan), shown left, which may be unique to this set of prints

Other than the above references, I have found no other information about his involvement with designing or carving woodblocks.
