From July 1970. Matsubara was not only the first route girl but the first female employed by Sega, as far as I know. Route workers during this time went around to the areas where Sega slot machines, electro-mechanical games and Rock-Ola jukeboxes were installed, collecting money from the machines and updating records in the jukeboxes for the latest songs.
Who knows? Maybe she did become a fully qualified mechanic. In any case, hats off to you, Ms. Matsubara!rsP yr
