Ladle to Battle

the 21st-centrury Problem

   Heat Island refers to urban areas hotter than surrounding rural regions. Bigger cities have more concrete structures that retain heat, grounds covered in asphalt, and heat-emitting automobiles, who all contribute to the unbearable summer heat.


   To tackle this, cities in Japan are bringing back an old tradition called uchimizu, water sprinkling in streets and gardens. Historically, it was considered to have purifying effect as depicted in many ancient scrolls. And it is scientifically proven that, when water evaporates in the summer heat, small amount of energy (0.58kcal/1g of water) is absorbed from surrounding air. Across Japan, uchimizu events are bringing people dressed in summer kimonos together to enjoy its ritual,  functional, and social aspect.


   Ken Tsunoda’s .58 is a big ladle made for uchimizu. The long and sturdy handle makes it easier to sprinkle bigger amount of water at once. The wood used is mahogany, whose resistance to water is well-known. This is the ladle to battle the 21-century problem of heat island with the ancient tradition.
