While I were in Osaka I visited the Namco Nipponbashi arcade and saw they had some temporary Haikyuu and Gangsta Chara Pop stores there so I took some pictures.
Some Haikyuu cardboard cutouts.
Lots of goods for sale.
The cashier area.
Gangsta cardboard cutouts.
Some chibi ones.
Gangsta lottery goods.
No location map since it's no longer there.
