The videos are narrated by voice actor Kappei Yamaguchi, who reprises his role as Kinoshita Hideyoshi from Ninja Girl & Samurai Master.
Historically, Nagahama City was the base of operations for Kinoshita Hideyoshi (aka Toyotomi Hideyoshi).
Nagahama City in Shiga Prefecture is the home of Nagahama Castle, a central location in Ninja Girl & Samurai Master (known in Japan as Nobunaga no Shinobi), and now the city and the TV anime have joined forces for a pair of promotional videos that highlight the local charms of Nagahama, including local cuisine and historical tourist destinations.
