Gunma Museum Hack 1.8 + Redeem Codes

"Gunma Prefectural Museum of History Navigation" is the Gunma Prefectural Museum of History's official app for providing exhibition descriptions and is for use within the museum.
The Gunma Prefectural Museum of History opened in October 1979.
Then, after large-scale renovation work from 2014, it was reopened in July 2016.
The history and cultural characteristics of Gunma Prefecture, from primitive, ancient, medieval, early modern, and modern times, are introduced in an easy-to-understand manner using images and models, centered on actual materials.
At present, the app can only be used in the National Treasure Exhibition Room. However, the area where the app can be used will be expanded in stages.
*The app is available in five languages: Japanese, Chinese (simplified and traditional), English, Korean, and Portuguese.
