Explore the Beauty of Niji No Matsubara
Stretching for more than five kilometers along the coast of Karatsu Bay, Niji no Matsubara (虹の松原) is one of Japan’s most scenic pine forests. Known as the “Rainbow Pine Forest,” this sweeping coastal grove contains more than 100,000 black pines, creating a unique natural barrier between land and sea. For centuries, it has protected the coastline from wind and sand while also becoming one of Saga Prefecture’s most beloved landscapes.
Today, Niji no Matsubara is recognized as one of Japan’s three great pine groves, alongside Miho no Matsubara in Shizuoka and Kehi no Matsubara in Fukui. With its combination of seaside beauty, forest tranquility, and historical background, it is a must-see attraction when exploring Karatsu.
The History of Niji no Matsubara
The origins of the forest date back to the early 17th century. During the Edo period, Terazawa Hirotaka, the first feudal lord of Karatsu Domain, ordered the planting of pine trees along the sandy shore. The goal was practical: to shield farmland and villages from strong coastal winds and prevent sand from drifting inland.
Over time, the pines grew into a vast, dense forest. While the original purpose was protection, the grove also became admired for its beauty. Locals began referring to it as Niji no Matsubara, or Rainbow Pine Forest, inspired by the shimmering interplay of light on the sea, sand, and trees — especially during sunrise and sunset.
Walking Through the Forest
Walking or cycling through Niji no Matsubara is one of the best ways to appreciate its atmosphere. The paths run parallel to the beach, shaded by towering pines that create a tunnel-like effect. The air smells fresh with pine resin, and the sound of waves filters through the trees from Karatsu Bay.
The trails are flat and easy, making them suitable for visitors of all ages. A stroll can take as little as 30 minutes, but many people linger longer, stopping at viewpoints, taking photos, or simply sitting on benches to absorb the quiet. Cyclists also enjoy the forest roads, which are wide enough for a leisurely ride.

Niji no Matsubara’s charm lies in its harmony of land and sea.
