The reason why the "voice of the sea" was delivered to the world was such a voice from overseas.
Even though I do not know the words, it seems that the honest feeling of Ura-chan's singing voice and the gentleness that wraps around grabbed the hearts of foreign people. When it is delivered, it seems that it is still in original Japanese.
For those who listen for the first time or those who have heard it, please take this opportunity to fully enjoy the charm.
