高知県いの町にある「にこ淵(にこぶち)」は、仁淀川の支流・枝川にひっそりとたたずむ神秘の滝壺。透明度の高い水が、太陽の光や季節の角度によってブルーやグリーンへと変化し、”仁淀ブルーの聖地”として多くの人を魅了しています。古くから水神の化身・大蛇が棲む神聖な場所とされ、地元の人々に大切に守られてきました。そのため、入水・飲食・ゴミの持ち込みなどは禁止。訪れる際は静かに、自然と信仰への敬意を忘れずに。現在は新たな遊歩道や展望台が整備され、駐車場から無理なくアクセス可能になりました。目的地設定は「グリーンパークほどの」が便利。そこから約10分で幻想的な青の世界に出会えます。
Niko-buchi, located in Ino Town, Kochi Prefecture, is a mysterious waterfall nestled quietly along the Edogawa River, a tributary of the Niyodo River. The crystal-clear water changes colour from blue to green depending on the angle of the sun and the season, captivating many visitors as the ‘holy place of Niyodo Blue.’ Since ancient times, it has been regarded as a sacred place where a giant snake, the incarnation of the water god, dwells, and has been carefully preserved by the local community. Therefore, activities such as swimming, eating, drinking, and bringing in trash are prohibited. When visiting, please remain quiet and respect both nature and the sacred beliefs associated with the site. Currently, new walking paths and observation decks have been developed, making it easy to access from the parking lot. Setting your destination to ‘Green Park Chodo’ is convenient. From there, you can reach the enchanting blue world in about 10 minutes.
