The land of Kitano was originally a land of frequent thunderstorms, and the god of thunder existed as the "god of fire and lightning" before the Tenmangu Shrine was established. It is said that a year with many thunderstorms will bring a good harvest because lightning discharges cause nitrogen fixation, which results in rich soil and a bountiful harvest. Lightning is considered to be terrifying, but on the other hand, it has the duality of giving fruitfulness. It is similar to fireworks (gunpowder), which I usually handle.
While I was experimenting with my work, I learned on the news that many pine trees at Kitano Tenmangu Shrine had been felled by a typhoon that hit Kyoto in September. In response to this, he hastily decided on a work in which pine trees are made to grow during the period by lightning. With the cooperation of Franklin Japan Inc., a lightning professional, data was obtained through a network when lightning strikes occurred within a radius of 1,000 km around Kitano Tenmangu Shrine. When lightning strikes, the black-and-white images are colored, and when a certain number of strikes occur, the pine trees are watered, and when more strikes occur, LEDs for growing plants are turned on. The more lightning strikes, the more energy is given to the pine trees. The more lightning strikes, the more the pine trees grow. Only the god of fire and thunder knows if the pine trees will grow during the exhibition period. After the exhibition, the grown pine trees were dedicated to Kitano Tenmangu Shrine.
When lightning strikes, water is given through the tube, and after a certain number of lightning strikes LEDs for plant growth change from red to blue to purple to encourage growth and nurturing.
When lightning strikes, the movie image is in color.
