Hashimoto's aspiration to become a driver stemmed from a part-time job she did at a gas station. She became acquainted with truck drivers and yearned to drive large vehicles. "I want to be a dump truck driver," she earnestly told a staffer at Hello Work Shinshiro, the local public employment assistance office. Around that time, Seisan Kotsu, based in Okazaki, Aichi Prefecture, which operates the S-Bus service, was looking for drivers, and in the spring of 2024, Hashimoto secured a job at the company. Normally, a class 2 large motor vehicle license is required for commercial passenger transport, but the S-Bus falls under the "private passenger transport for hire" category according to the Road Transportation Act, allowing her to drive with only a large motor vehicle type 1 license.
