This is a live performance of the song Byakkoya (White Tiger Field) from the 2006 homonym album. The lyrics are slightly different from the song in the Paprika Soundtrack, which is called The Girl in Byakkoya. Now, the lyrics from the original album (didn't find an english translation).
Enjoy.


~ BYAKKOYA (WHITE TIGER FIELD) ~

Yoi ya nonde jinrui geko bihai
Yoi ya nonde jinrui geko bihai

Tooku no sora Mawaru hana no enjin no kamabisushisa ni
Ano hi ya Ano hi ni koetekita bunki ga me wo samasu

AOZAI no musume ga fuku kaze no michi wo saseba
Takadai ni arawareta na mo shiranu hirono wa hi wo ukete

Yoi ya nonde jinrui geko bihai
Yoi ya nonde jinrui geko bihai

Are ga yume de miseta machi to kage no koe ga sasayaita
Kuru hi mo Kuru hi mo ikusen no bunki wo koeta toki

NONRAA no kenjin ga suterareta michi wo sashite
Umizoi ni Umizoi ni mi mo shiranu honoo wo odoraseta

Aa MANTORU ga jouzetsu ni hi wo fukiageteSuterareta no ni tatsu hito wo iwau yo
Aa Shizuka na shizuka na musume no shiya de Aa mishiranu miyako ni hi ga tomoridasu

Yoi ya nonde jinrui geko bihai
Yoi ya nonde jinrui geko bihai

Takaku sora shu ni some Ano noboru honoo no kiseki ni wa
Ano hi ya Ano hi ya ano toki ni nakushita michiyadoshi

AOZAI no suso wo fuku Kaze wo oi saka wo kudari
Kawazoi ni Kawazoi ni mi mo shiranu no shifuku no hana wo mita

Aa MANTORU ga jouzetsu ni hi wo fukiagete Suterareta no ni tatsu hito wo iwau yo
Aa Shizuka na shizuka na musume no shiya de Aa mishiranu miyako ni hi ga tomoridasu
Aa MANTORU ga jouzetsu ni hi wo fukiagete Suterareta no ni tatsu hito wo iwau yo
Aa Shizuka na shizuka na musume no shiya de Aa mishiranu miyako ni hi ga tomoridasu

Yoi ya nonde jinrui geko bihai
Yoi ya nonde jinrui geko bihai
