Named after Edo Tokyo Hakubutsukan [Edo Tokyo Museum], HyperEDOHAKU recreates the world of Edo in 3DCG for you to wander around and collect the many items in the Museum’s collection. As a boy living in a Nagaya in Ryogokubashi, you will experience the many cultures of Edo such as the opening of the Sumida River.

As Edohakun (Mr. Edohaku), you can tap and drag on the character to move around the streets of Edo. As you wander around the rooms and streets, you will find items, 100 in total,  that are outlined in white–these are items from the Edo Tokyo Museum’s collection that you want to collect. Tap on the people you meet and places you wander around to get clues on where these items are. As you discover and collect items, your story in Edo will unfold to different areas.

The period of the app is of Tokyo during late Edo (1746 – 1841). The spatial rendition is based on the model of Area to the west of Ryogokubashi Bridge (recreated by the Edo Tokyo Museum), with features taken from artifacts of the Edo to Meiji period scattered throughout. You can find out more about each of the 100 items from the Museum’s collections from each of their captions.
