Walk around village in mountain valley and think of history.
Castle wall standing at 325mt. high plateau. Oka Castle is known as impregnable castle all through Sengoku era/Edo Period.
In twilight, or cherry trees veiled in haze during spring, stonewall only reflects prosperity and decline of history.
While walking around Ruins of village in mountain valley and devoting yourself to breath of nature, bustle of vegetation plays song.
