请问太阳帝国中suo-gan的歌词是什么语言

英文

歌名“Suo-Gan” 维也纳童声合圆灶陪唱团演唱辩友

Hunan blentyn, ar fy mynwes
Clyd a chynnes ydyw hon
Breichiau mam sy'n dyn amdanat
Cariad mam sy dan fy mron
Ni chaiff dim amharu'th gyntun
Ni wna undyn a thi gam
Huna'n dawel, annwyl bientyn
Huna'n fwyn ar fron dy fam
Huna'n dawel hana huna
Huna'橘蠢n fwyn y del ei lun
Pam yr wyt yn awr yn gwenum
Gwenu'n dirion yn dy hun
Ai angylion fry sy'n gwenu
Charlotte Church
Arnat yno'n gwenu'n lion
Titha'u'n gwenu'n ol a huno
Huno'n dawel ar fy mron
Paid ag ofni, dim ond deilen
Gura, gura ar y ddor
Paid aga ofni ton fach unig
Sua, sua ar lan y mor
Huna blentyn nid oes yma
Ddim i roddi iti fraw
Gwena'n dawel ar fy mynwes
Ar yr engyl gwynion draw
To my lullaby surrender
Warm and tender is my breast
Mother's arms with love caressing
Lay their blessing on your rest
Nothing shall tonight alarm you
Lie contented, calmly slumber
On your mother's breast, my dear
Here tonight i tightly hold you
And enfold you while you sleep
Why, i wonder, are you smiling
Smiling in your slumber deep?
Are the angels on you smiling
And beguiling you with charm
While you also smile, my blossom
In my bosom soft and warm?
Have no fear now, leaves are knocking
Gently knocking at our door
Have no fear now, waves are beating
Gently beating on the shore
Sleep, my darling, none shall harm you
Nor alarm you, never cry
In my bosom sweetly smiling
And beguiling those on high

应该是日文，要么影片里的日本军官为什么流眼泪呢。

是威尔士语，比较偏的语种
