Geobreeders is set in in the fictional Ayagane City, which is based on modern-day Nagoya. Many of the train station names are either alternative spellings to those in Nagoya, or have identical names with parts of the kanji whited out. The action is set in "Showa era" 73 and 74 (1998 and 1999), keeping in mind that the Showa ended in 1989.
