The district court in Sendai sentenced him to life imprisonment on March 30, 2004, for one murder and four attempted murders.{{cite web|url=http://www.japantimes.co.jp/weekly/news/nn2004/nn20040410a6.htm|title=Nurse gets life for patient slaying|publisher=The Japan Times WEEKLY|date=2004-04-10|access-date=2008-03-22}} Japanese police insisted that vecuronium's molecular mass is 258, but its correct molecular mass is 557. His defense pointed out this contradiction on the high court, but the high court in Sendai upheld the original sentence on March 22, 2006. He appealed to Supreme Court, which upheld the sentence on February 25, 2008.{{cite web|url=http://www.hdrjapan.com/option,com_myblog/show,Top-court-dismisses-nurses-protest-over-life-sentence-for-murdering-patient.html/Itemid,67/ |title=Top court dismisses nurse's protest over life sentence for murdering patient |author=Mainichi Shimbun |author-link=Mainichi Shimbun |publisher=HDR Japan |date=2008-03-12 |access-date=2008-03-21 |url-status=dead |archive-url=https://web.archive.org/web/20110711154526/http://www.hdrjapan.com/option%2Ccom_myblog/show%2CTop-court-dismisses-nurses-protest-over-life-sentence-for-murdering-patient.html/Itemid%2C67/ |archive-date=2011-07-11 }}
