I brought the mini-size cut-out of "Osaka Subway Girl" and "Osaka Subway Boy" to Osaka, following the trip in 2022. I made the new ones smaller and with different facial expressions.
The first and second photographs are in 400 Series. The first is in front of a USB charging spot, and the second is in a transverse seat carriage.
The fourth is at Orchid Time by Osaka Metro with takoyaki octopus balls. I imagine they would like to eat takoyaki.
The fifth is at Minoh-kayano Station on Kita-osaka Kyuko Railway Namboku Line. Though it isn't a station on Osaka Metro Lines, the half trains on Midosuji Line go through Namboku Line and terminate there.
The sixth and seventh are in "e METRO MOBILITY TOWN". The sixth is at the photo spot with a 400 Series 3-dimensional art, and the seventh is on a table in the food court with red-coloured "Midosuji Line" soda pop.
