Niji no Matsubara Pine Grove

Niji no Matsubara (虹の松原) is a breathtaking five-kilometer stretch of coastline, just outside Karatsu city center, adorned with approximately a million pine trees. Planted during the Edo Period, the grove was originally intended as a natural seawall to safeguard the coastline from the harsh sea winds and waves. Over time, it has grown into one of Japan's most famous pine groves, ranking alongside Miho no Matsubara in Shizuoka and Kehi no Matsubara in Fukui Prefecture. This magnificent natural monument is not only a testament to the region’s history but also a prime example of Japan's efforts in environmental preservation.

Stretching along the scenic Karatsu Bay, Niji no Matsubara offers visitors a tranquil escape where they can stroll through the towering pines, enjoying the harmony between nature and the sea. A wide sandy beach runs parallel to the grove, providing a peaceful spot to relax and take in the views. A winding road passes through the grove, inviting visitors to enjoy leisurely walks under the shade of the pines while gazing out over the sparkling waters. Whether you're seeking a quiet moment of reflection or a scenic walk, this picturesque location offers a perfect blend of natural beauty and historical significance.
