What is light in japanese word?

In Japanese, light is written as 光 (hikari). It is a commonly used word in everyday language and can refer to different types of light, such as sunlight (太陽の光, taiyo no hikari) or artificial light (人工光, jinko hikari). It is also used in idiomatic expressions such as "light at the end of the tunnel" (トンネルの出口に光が見える, tonneru no deguchi ni hikari ga mieru) to represent hope or a positive outlook. In traditional Japanese culture, the concept of light is often associated with enlightenment, clarity, and purity. There are also several Japanese festivals that celebrate the beauty and symbolism of light, such as the Yamagata Hanagasa Matsuri and the Uji Tori Matsuri.
