Ishidake Observatory

The Ishidake Observatory, atop Mount Ishi south-west of central Sasebo, is the second great viewpoint over Kujukushima, the Ninety-Nine Islands, and for many photographers it is the finest. Quieter than the famous Tenkaiho, it offers an equally sweeping panorama of the island-scattered sea, framed a little differently, and it has become a favourite spot for capturing the islands at sunset.

Kujukushima, a maze of more than two hundred small forested islets set in sheltered waters within the Saikai National Park, is the natural glory of the Sasebo coast. From the deck at Ishidake the view opens across this labyrinth of green islands and blue channels, with the pearl and oyster rafts of the Pearl Sea and, on clear days, the distant horizon beyond. The composition here is subtly different from Tenkaiho, and many find it especially photogenic in the low light of morning and evening.

The observatory is well known among landscape photographers, who prize the layered view of islands receding into the haze, particularly at sunset when the sea and sky take on warm colours and the islets turn to dark silhouettes. Ishidake also has a small claim to cinematic fame, having appeared as a filming location for a celebrated samurai film, which adds a note of interest to the visit. Being less crowded than Tenkaiho, it often feels more peaceful, a quiet place to watch the day end over the islands.

A notable feature is the way the two observatories complement each other. Visitors with time can compare the panoramas from both Tenkaiho and Ishidake, each giving a distinct perspective on the same remarkable seascape, and together they confirm why the Ninety-Nine Islands are considered one of the scenic treasures of Kyushu.

The visiting experience is easy but involves a short climb. From the car park a walk up leads to the observation deck, so the rating is moderate rather than effortless, though the path is short and manageable for most reasonably active visitors. There are restrooms and parking, and around forty minutes is enough to enjoy the view; those coming for sunset will want to stay longer. As at any hilltop, a light layer is useful against the breeze, and care is needed on the paths after dark.

The view is rewarding in any season, the islands remaining green year-round and clear days offering the sharpest scenes; sunset is the ideal time. Because it is outdoors and exposed, it is at its best in fine, settled weather.

Getting there is easiest by car, about twenty minutes from Sasebo Station up to Mount Ishi, followed by the short walk to the deck. Parking is available. Combined with Tenkaiho and a boat cruise from the Pearl Sea Resort, Ishidake completes a full appreciation of Kujukushima, and for photographers chasing the perfect island sunset, it is arguably the best vantage point of all in western Nagasaki.
