As Japanese, I want to give you "samurai-name generator".
But my English is poor, so I hope you understand what I'm saying...
(Web pages mentioned in this thread as name generator list many unlikely Japanese names...)
My methods generate personal name for male, and they are old-fashioned and samurai-like ones.
Of course, actual Japanese names have much more variation.
method 1
Take one of bellow as prefix.
kei,sou,kan,ryuu,ken,mune,gan,syun,kin,man,you,yuu,shin,gin,kou,jin,jyun,
Take one of bellow as suffix.
ichi,ichirou(first son),
ji,jirou(second son),
zaburou(third son),
shi,shirou(fourth son),
go,gorou(fifth son),
roku,rokurou(sixth son),
shichi,shichirou(seventh son),
hachi,hachirou(eighth son),
ku,kurou(nineth son),
tarou(provably first son)
suke,
zou
for example:
kei-ichi,kei-ichirou,kei-suke,sou-jirou,jyun-tarou,kou-zou
method 2 (this method gives you more samurai-like name than method 1)
Take different two of followings and put togather. Order doesn't matter.
masu,toki,yuki,teru,tada,yoshi,toshi,mune,kane,ie,tsuna,nori,sada,haru,aki,mure,masa,
for example:
masu-toki,toki-masu,teru-tsuna,nori-teru,mune-ie
