Fukuoka and Saga prefecture in Northwest Kyushu area faces Genkainada channel to the the Korean Peninsula and continental Asia between East Sea and Yellow Sea. The area has been one of the the major places for foreign trading, diplomacy and national defense as well. 太宰府 Dazaifu (government) established for the regional government in Kyushu from the 8th to the 12th centuries. The town of Dazaifu grew up around the civil and military headquarters of the regional government.
During the Medieval period in northwest Kyushu area, there were two major lineages of 左文字 Samonji and 金剛兵衛系 Kongobei.
The celebrated lineage of 左文字 Samonji was founded 良西 Ryosai - 入西 Nyusai - 西蓮 Sairen - 実阿 Jitsua - 左文字 Samonji who were Buddhist priests under the patronage of 善導寺 Zendouji temple.
西蓮 Sairen who is a son of 良西 Ryosai, an elder brother of 入西 Nyusai, initially named himself 国吉 Kuniyoshi then changed 西蓮 Sairen of Buddhist monk's name. He worked for 鎮西談議所 Chinzei Dangisho (a court of justice/town office) where belonged to 善導寺 Zendouji temple. For that days and ages, there were major military efforts the Mongol invasions of Japan (元寇 Genkō) of 1274 and 1281 undertaken by Kublai Khan and there were considerable large number of demands from the Samurai worriers.
The subject Katana was substantially shortened in the early Edo period, upholds the tradition of ancient Yamato school with fine steel that holds rather soaked and classical impression and forging scene indicates conspicuous Mokume, Itame and flowing Masame ware to say that "Full of Pastoral Beauty" which is the major character of ancient Koto blade in Kyushu. The judgement of 西蓮 SAIREN is surely appropriate under such major character of superb workmanship.
