A Day in the Life of a Japanese Construction Worker in Tokyo Japan. This is typical work day in Japan for construction work who operates an Excavator construction vehicle. This is her work hours in Japan as well as her morning routine and after work schedule. Kaori operates various construction vehicles such as bulldozers and backhoes, but her speciality are Yumbos, AKA excavators the Japanese name dating back to the 1960’s when they were first produced and named as such. Ever since then, the name Yumbo has become synonymous with all excavators in Japan. And to operate these construction vehicles specialized licenses in Japan are required in addition to a large-sized vehicle driver’s license if driven on roads, in total Kaori had to test for 4 different licenses in order to do her job. It was only until Kaori’s late 20’s did she find interest in her career, working as an office cleaner, she noticed excavators from her office window dreaming how fun it would be to operate.
