A Scenic Drive Through Saikai National Park
Your adventure begins with a comfortable private car ride through Saikai National Park. This park is renowned for its unique karst formations and serene coastal landscapes. During the drive, you’ll get a sense of Kyushu’s rugged beauty, with the shimmering Kujukushima Islands dotting the horizon. It’s a perfect warm-up, setting the scene for what’s to come.
The Glass-Bottom Boat Cruise
Next, you board a glass-bottom boat — a highlight of the tour — that takes you around the Kujukushima Islands, often called the “ninety-nine islands” for their picturesque, forested islets. The boat allows you to see marine life through its transparent bottom, a fun surprise for kids and adults alike, and provides an intimate look at the natural environment without disturbing it.
Multiple reviews emphasize how the boat ride allows travelers to appreciate the scale and diversity of the islands. One reviewer mentioned, “It was incredible to see the fish swimming beneath us, and the views of the forested islets above created a perfect contrast.” The boat also tends to be smooth and stable, making it accessible for most.
The Observatories: Ishidake, Yumiharidake, and Tenkaiho
After the cruise, your day continues with visits to three notable observatories.
Ishidake Observatory stands out as a cinematic location. It was a filming site for The Last Samurai, adding a touch of Hollywood to your scenic day. The panoramic views from Ishidake are spectacular, offering a broad sweep of the islands and coastline. It’s a spot that combines natural beauty with a touch of film history, which adds an extra layer of interest.
Yumiharidake and Tenkaiho observatories** are equally memorable. The former is celebrated for its flower fields and lush forests, especially beautiful during blooming seasons, while the latter provides sweeping sea vistas and seasonal flowers.
One traveler described Tenkaiho as “a sea of color during spring and summer, with flowers blooming alongside incredible views,” making it a photographer’s dream. Both spots involve some walking, with stairs and uneven surfaces, so comfortable shoes are a must.
