According to The Vault(Fallout wiki):
A rough translation of some of Toshiro's dialogue is as follows:
* "Onushi wa nanimono? Koko wa dokoda?" o "What/who are you? Where is this place?" * "Sessha no ken! Sessha no ken wa dokoda?" o "My sword! Where is my sword?" * "Sappari wakaranai. Koko ga doko nanoka mouse. Sessha no ken wa doushita? o "I don't understand [you] at all. Tell me where this place is! What has become of my sword?" * "Sessha no ken wa dokoda? Ima sugu kaesanu ka?" o "Where is my sword? Return it now!" * "Nani wo itteorunoda. Sappari wakaran. Nantoka shitekure!" o "What are you saying? I can't understand. Please do something!" * "Nantoka senuka! Sessha no ken wa ittai doko ni aru no ka?" o "Won't you do something?! Where the hell is my sword?" * "Nani wo itte orunoda. Kono chi ni mioboe no nai. Ittai sessha ni nani wo shita?" o "What are you saying? I have no memory of this world. What in hell has been done to me?" * "Sessha no ken wo imasugu kaesunoda. Hayaku kaesanu ka." o "Return my sword immediately. Hurry and return it!" * "Onushi wa ittai nani mono? Sessha wa naze koko ni iru?" o "What on earth are you? Why am I here?" * "Sessha no ken wa do natta. Eei, hayaku kaesanu ka!" o "What happened to my sword? Argh, return it at once!" * "Youkai kara mi wo mamoru niwa, ken ga iru!" o "I need my sword to defend against [these] demons!" * "Nani ga okotta no ka, kento tsukanu." o "What has happened? I do not have my sword!" * "Youjutsu de sessha wo toraete youkai me. Kono mama de wa okanu zo!" o "These wretched demons have taken me captive with their sorcery. I cannot be left like this!" * "Ken wo ubawarete shimatta, taegataki kutsujoku!" o "I have been robbed of my sword - this is an unbearable disgrace!" * "Ken wo sugu torimodo saneba naranu!" o "I must take back my sword immediately!" * "Hito wo azukeru na. Onushi no monoii wa sappari wakaran." o "Do not insult me! I cannot understand a word you are saying." * "Sessha wo tasuke takuba, sessha no ken wo sagashi dase!" o "If you want to help me, go and search for my sword!" * "Nanto? Nani wo nozonde orunoda. Nani yue, onushi no iu koto ga wakaranu no da?" o "What? What do you want? How is it that I have no idea what you are saying?" * "Onushi, naniyue sonoyo ni hanasu? Nanika shomo no mono demo arunoka?" o "You, why are you talking like that? Is there something you want?" * "Oh, sessha no ken! Kaeshite moraerutowa, katajikenai." o "Oh, my sword! I am most grateful for its return!" * "Oh, korekoso sessha no ken. Katajike nai." o "Oh, this is my sword! My utmost thanks!" * "Sumanuga, sessha mizukara korekara okorukotoni sonaeneba naranu." o "I am sorry, but I must now prepare myself for what is to come."
* "Jyama wo suru na." (after finding his Samurai's Sword) o "Don't get in my way."
Good job getting most of it. But do you think you can get more of it done? Like what does he say in English when he says:
"Kotoba de wa tamashii wo iyasezu. Chinshi mokko aru nomi."
"Mokuteki naki okonai wa tadano kaze, ketsui aru okonai wa hue no shirabe to naru."
"Hajimari ni ketsumatu wo mi, ketsumatsu ni hajimari wo miru. Soremade wa dojite wa naran."
"Tatakai no kachimake ha, seme to seme no hazama ni aru."
"Iretekure! Sessha wa eirian deha gozaran. Sessha wa samurai nari. Otanomi mosu!"
"Ya, kore wa katajike nai. Soregashi ni dekiru kotoga gozareba nannarito."
