What is the Okaizu Bunsuiko Cherry Blossom Tree-Lined Path｜Niigata Prefecture’s Spectacular Cherry Blossom Viewing Spot
The Okaizu Bunsuiko Cherry Blossom Tree-Lined Path is a cherry blossom tree-lined path spanning approximately 10 kilometers in the Gosenseki area of Tsubame City, Niigata Prefecture. Somei Yoshino cherry trees planted along the embankment of the Okaizu Bunsuiko, a water division route of the Shinano River, bloom all at once in spring, enchanting visitors.
Reasons for Selection to Japan’s 100 Best Cherry Blossom Viewing Spots
The Okaizu Bunsuiko Cherry Blossom Tree-Lined Path was chosen for “Japan’s 100 Best Cherry Blossom Viewing Spots” due to its scale and scenic beauty. The sight of approximately 2,600 Somei Yoshino trees lining the embankment is awe-inspiring, offering an experience of walking through a cherry blossom tunnel. Furthermore, the contrast between the majestic flow of the Shinano River and the cherry blossoms creates a unique landscape not seen elsewhere.
Behind the cherry blossom tree-lined path lies the history of the Okaizu Bunsuiko construction project, called a project of the century, and the value of this place is recognized not only as a cherry blossom viewing spot but also as an important location that tells the story of Niigata Prefecture’s flood control history.
Spectacular Spring Scenery Created by Approximately 2,600 Somei Yoshino Trees
The greatest attraction of the Okaizu Bunsuiko Cherry Blossom Tree-Lined Path is the scale of approximately 2,600 trees. In fact, when the Okaizu Bunsuiko project was completed, approximately 6,000 cherry trees were initially planted, and approximately 2,600 still remain today, blooming beautifully each year.
The cherry blossom tree-lined path stretching endlessly along the embankment can be enjoyed both on foot and from a vehicle. In particular, the hiking course from the Shinano River Okaizu Museum to the Okaizu Bridge is a popular route where visitors can leisurely appreciate the cherry blossoms while feeling the breeze from the river. Due to its riverside location, the bloom time tends to be slightly later than in Niigata City, with early to mid-April being the most beautiful period.
History of the Okaizu Bunsuiko｜The Project of the Century and the Birth of the Cherry Blossom Tree-Lined Path
When discussing the Okaizu Bunsuiko Cherry Blossom Tree-Lined Path, one cannot overlook the history of the Okaizu Bunsuiko construction project that forms its background. This grand project is still told as a “project of the century” that significantly contributed to Niigata Prefecture’s development.
The Achievement of a Flood Control Project that Saved the Echigo Plain
The Okaizu Bunsuiko is a water division route built for the purpose of flood control of the Shinano River. The Echigo Plain was historically plagued by devastating floods from the Shinano River. Planning proceeded from the Meiji era onwards with the aim of mitigating flood damage in the lower basin by directing part of the swollen water directly to the Sea of Japan.
The construction faced tremendous difficulties, but was completed in 1922 (Taisho 11). The completion of the Okaizu Bunsuiko greatly reduced flood risks in the Echigo Plain, making a significant contribution to the region’s agricultural and industrial development. Built at the location closest to the Sea of Japan where the Shinano River makes a dramatic turn eastward, this water division route continues to function as an important flood control facility for Niigata Prefecture today.
The Story of Cherry Blossoms Planted to Commemorate Project Completion
The cherry blossoms of the Okaizu Bunsuiko Cherry Blossom Tree-Lined Path were planted to honor this great achievement. In fact, cherry tree planting began before the project’s completion, and approximately 6,000 Somei Yoshino trees were planted along the embankment by construction workers and local residents.
These cherry trees symbolized not only beautification of the landscape but also gratitude to those who accomplished the difficult construction project and hope for the Echigo Plain’s new future. The approximately 2,600 cherry trees that remain today include some over 100 years old, continuing to watch over Niigata Prefecture’s flood control history and regional development.
