Unfortunately I don't have a Japanese encoding available here. But thanks for the links! I did notice one typo (two whom should I point it out?) in the third hymn:
Ametustchi no mimaki o ba
obviously should be
Ametustchi no mikami o ba
(I've sung this as a solo in my English-speaking church, as well as in Japanese church services; "mimaki" sounds like a sanctified California Roll!)
