We come together by joining the riverfront activities in the "Hiroshima River City Festival"


In order for Hiroshima to attract more visitors and continue to be a vibrant city, it is not only necessary to maintain the status quo, but also to create further attractions.The history of Hiroshima has been closely linked to the developments of the Ota River system.We like to reinstall the "Hiroshima River Festival" held from 1952 to 1976 by starting the "Hiroshima River City Festival."However, we are not simply wishing to restore the festival held in the past but wishing to initiate the bigger movement of bringing people together by joining the riverfront activities to create a new culture/tradition that is "healthy," "beautiful," and "peaceful" suitable for the water city Hiroshima to match today's lifestyles.

We come together by paddling on the river "RiverDo!"


Hiroshima has six rivers flowing through the city and has the largest number of over 300 Gangis, staircase-like structures, found in Japanese cities. Gangis were used for loading and unloading goods and passengers in the past when boats were used instead of cars and trucks to transport them. We can re-utilized this old but world's rare infrastructure that is unique to Hiroshima. The lifestyle changes brought us new challenges: we need to think about riverfronts as parts of the ecosystem starting in the mountains and connected to the rivers and leading to the ocean. We need to be mindful of the sustainable development goals outlined in the SDGs adopted by the United Nations. 

The Hiroshima River City Festival is the celebration of the Ota River's water fronts which have been serving as the "homes of the souls" of people in Hiroshima.

We come together by joining the riverside activities "RiverDo!"



The live music concerts and marches will take places near Gangi on the riverbanks. Along with the SUP race around the city, the festival will feature many other activities near or on the riverfront areas including riverside running and walking, cycling, riverside cleanup events and camping style picnics. At the festival’s main venue, live performance shows will be held and workshops for learning and thinking about the river environment will be offered.

We help to sustain the Healthy Ocean Environment "RiverDo!"


Marine plastic pollution is also occurring in the nearby Seto Inland Sea. Most of the plastic waste flows from the local rivers into the Seto Inland Sea.which is semi-enclosed and exchanges very little water with the Pacific Ocean or Japanese Sea.Let's start with the actions we can do ourselves to sustain the healthy ocean environment.
