After this, Saigo, Murata, and Shinzo MORIYAMA went to Kyoto to investigate the situation in each domain before the troops led by Hisamitsu SHIMAZU departed, which made Hisamitsu suspect that their actions had instigated Izumi MAKI and Shinshichi ARIMA to raise an army in Kyoto (Teradaya-sodo [oppression of Sonjo group]); after being called back from Kyoto, Saigo was sent into exile to Tokuno-shima Island (and changed to Oki-no-erabujima Island by the second order) and Murata to Kikai-jima Island (not Satuma-iojima Island [Kikai-ga-shima Island]).
この後に島津久光進発に先立って上京した西郷・村田・森山新蔵は諸藩の情勢を探っていたが、真木和泉・有馬新七らの京都挙兵（寺田屋騒動）を煽動したと久光から疑われ、呼び戻されて西郷は徳之島（再命で沖永良部島へ変更）へ、村田は喜界島（薩摩硫黄島（鬼界ヶ島）ではない）へ遠島された。
