In Koga City, Fukuoka Prefecture, lies Japan's number one company in the glow stick industry. The founder and current president, Mr. Harada Shiro, is still actively involved in product development at the age of 78. Glow sticks are a must-have for pop idol concerts in Japan, and they also produce light-up bobbers for night fishing. Their headquarters boasts a pizza oven in the garden, where the employees enjoy a special lunchtime treat featuring the president and staff's signature dishes under the blue sky.
