Time machine

得意げに呟いた　心配ないからと

tokuigeni tsubuyaita shinpainaikarato

You murmured proudly that you had no worries

人の少ないホームで　ヘタクソ\に強がった

hito no sukunai hoomu de hetakuso ni tsuyogatta

 You pitifully bluffed in a place that people rarely pass

唐突に鳴り響く　僕を呼ぶ別れの音

toutotsu ni narihibiku boku wo yobuwakare no oto

The sudden sound of goodbye that calls me

見慣れたその泣き顔も　しばらくは見れないね
minareta sono nakigao mo shibaraku wa mirenaine

I guess I can't see the familiar crying face for some time 
声が遮られていく　身振り手振りで伝える

koe ga saegirareteiku miburiteburi de tsutaeru

Voice is blocked and communicating with gestures
「いってらっしゃい」のサイン
"itterasshai" no sain

The "Come back safely" sign

..... 

少しずつ小さくなってく　全部置いたまま

sukoshi zutsu chiisakunatteku zenbu oitamama

 I threw away all the things that were getting smaller

悲しくなんかないさと　イヤホンで閉じ込めたよ

kanashi kunankanaisato iyahon de tojikometayo

I murmured about how I wasn't sad and put on the earphones

.....

見えたんだぼんやりと　暖かい昨日のビジョン

mietanda bonyarito kotatakai kinou no bijon

 I could see it a little - the vision of the warm past days

右と左に広がって　僕を連れて行くのさ

migi to hidari ni hirogatte boku wo tsurete ikunosa

To the right, to the left, it spreads and takes me with it

僕の横をすり抜けて　遠ざかっていく景色

boku no yoko wo surinukete toozakatte ikukeshiki

 The scenery passes me and is getting further away

あの日の僕を置いてく

ano hi no boku wo oiteku

It leaves that day's me behind

 

.....

こぼれた涙一滴（ひとしずく）の　意味も分からずに

koboreta namida hitoshizuku no imi mo wakarazuni
Not knowing the meaning of the one teardrop

タイムマシンにゆられて　明日も元気でいるよ

taimumashin ni yurarete ashita mo genki deiruyo

 I wish that you'll be healthy and be shaken by the time machine

.....
 

こぼれた涙一滴（ひとしずく）の　意味も分からずに

Not knowing the meaning of the one teardrop

タイムマシンにゆられて　明日も元気で

taimumashin ni yurarete ashita mo genki de

I wish that you'll be healthy and be shaken by the time machine

溢れる涙抑えきれず　意味も分からずに

afureru namida osaekirezu imi mo wakarazuni

Not able to hold back the overflowing tears, not knowing the meaning

タイムマシンにゆられて　また戻ってくるよ

 taimumashin ni yurarete mata modottekuruyo

I'll be shaken by the time machine and come back again
