Yaeyama (八重山?) was an unprotected cruiser of the Imperial Japanese Navy. The name Yaeyama comes from the Yaeyama Islands, the southernmost of the three island groups making up current Okinawa prefecture. Yaeyama was used by the Imperial Japanese Navy primarily as an aviso (dispatch boat) for scouting, reconnaissance and delivery of high priority messages.
Yaeyama was designed under the supervision of French military advisor Emile Bertin, and built in Japan by the Yokosuka Naval Arsenal. Her engine, a three-cylinder triple-expansion steam engine supplied a pair of six cylindrical boilers was imported from Hawthorn Leslie and Company in England. With a small displacement, powerful engines, and a 20.75-knot (38.43 km/h) speed, the heavily armed and lightly armored Yaeyama was an example of the Jeune Ecole philosophy of naval warfare advocated by Bertin. Due to its small size it is sometimes classified as a corvette or gunboat.
Yaeyama was the second domestically-produced steel-hulled vessel in Japan. It retained a full barque rigging with two masts for auxiliary sail propulsion in addition to her steam engine. Yaeyama was armed with three QF 4.7 inch guns and eight QF 3-pounder Hotchkiss guns. In addition, she carried two torpedoes, mounted on the deck.
