Commemorating the 40th anniversary of the establishment of the city The 41st Urayasu City fireworks festival ? A fiery strong fireworks. Urayasu's fireworks everyone was shouting "Kagiya!" and Tamaya and Kagiya were worried and looked it up. It seems to be the name of a fireworks master who was active in the Edo period ... Kagiya seems to be a popular fireworks master who has grown to become a purveyor of the Edo shogunate! I learned about "Tamaya" and "Kagiya" for the first time from the Edo period!
