It’s an ending song of an animation. The melody was good, there was a Japanese version song on YouTube and I used it to learn some vocabulary in Japanese. It’s fun to be able to read Japanese kanji and to write furigana.

Translation of my own :
Swallows fly away not knowing the way back
Playing koto, feelings grow
Who laments the coming and going of life
The past can not be changed
Drinking alone under the mountain
Leisurely walking around the peach blossom paradise
Who makes the flute echo
Days gone by can not return
Please don’t forget what I was looking for
A day fades while I travel across the mountains and rivers
In the dim light, glimpses of a familiar face
Stirring emotions in my heart
Going through adversity
White robe reflects those of crow black
Stretched out, gazing at the twilight,
Watching
Swallows fly away not knowing the way back
When would be the time to go back
Who laments the coming and going of life
Even for once I wish to meet you
Beautiful moon I look at from my small boat
Leisurely walking around the peach blossom paradise
The loop of reincarnation no longer concerns me
Days gone by can not returned
Please don’t forget what I was looking for
A day fades while I travel across the mountains and rivers
In the dim light, glimpses of a familiar face
Stirring emotions in my heart
The two close together now
Playing the koto and flute
Forever and ever
I want to be gazing at you only
Please don’t forget what I was looking for
A day fades while I travel across the mountains and rivers
In the dim light, glimpses of a familiar face
Stirring emotions in my heart
The two close together now
Playing the koto and flute
Forever and ever
I want to be gazing at you only
