We have participated in the event "Nihonbashi Bridge Washing", which washes Nihonbashi with a deck brush. Nearly 2,000 people gathered in Nihonbashi, dressed in unique costumes such as happi and T-shirts for each company and organization.
This event is the only event that citizens touch the actual "Japan Road Mark" in the center of the bridge (probably). Three water sprinklers from the Tokyo National Highway Office of the Kanto Regional Development Bureau of the Ministry of Land, Infrastructure, Transport and Tourism and three fire trucks from the Tokyo Fire Department will also run out, and the event will be excited by watering the road surface and watering with hoses. After children in the ladder car polished the nameplate of Nihonbashi, which was attached to the capital height over Nihonbashi, the Tokyo Fire Department and the fire brigade released water to make the nameplate shiny.
You can see that Nihonbashi is really loved locally. According to experts, Nihonbashi is a bridge structure that can be used all the time if maintenance is continued with chitin. Nihonbashi, which was first bridged in 1603, would like to support it through the cooperation of citizens and experts so that it can continue to be the center of Japan's transportation network for many years to come! ! ！
