Nagushiyama is a mountain in Sasebo, Nagasaki Prefecture, which sits at 234 meters in height. The mountain offers panoramic views of the cityscape, harbor, and surrounding mountains, making it a popular destination for nature enthusiasts and photographers alike. It's a particularly stunning spot during the spring months when thousands of azalea bushes bloom in shades of pink, red, and white, and an annual festival is held during this period to celebrate the flowers.
The event has been running for over 40 years now, and there is a small admission fee of ¥500 charged during the azalea blooming period.
