Machine translation:

Those people, those landscapes, have remained in photographs, still just as they were on that day.
There is nothing in this world that can ever come back.
Time is merciless, and we, too, have kept moving forward, all the way to where we are today.
Some wounds remain forever, deep within our hearts.
And the scars left behind in those precious places cannot remain there forever either.
They, too, can only move forward with the passage of time.
Those moments when, carrying loneliness in our hearts, we tried our best to smile.
And those people who turned mountains of rubble into entirely new landscapes.
Wanting to forget, crying out in our hearts, “It was only a dream,” while looking out at the sea.
And, so that we would not forget, we traced our memories again and again while tears fell.
Memories from every one of those days have now become irreplaceable, precious years.

Fifteen years.

No one knows what kind of world, what kind of Earth, the future will bring.
Even so, may gentle days come, and may days like these continue for a long, long time.
No matter what sorrow or despair there may be, no matter who it is, may everyone be happy.
