Satsuma Domain invaded Ryukyu in the spring of 1609. When Satsuma troops approached Naha, Gushichan Chōsei led a mission to hold peace talks at Oyamise (). Tomigusuku Seizoku, Kikuin, Kian, Ikegusuku Anrai, Esu Seishō () and Tsuken Seisoku () were sent as assistants. Neither Kabayama Hisataka nor Hirata Masumune appeared at the peace talk, and the peace proposal was rejected by Satsuma.
