Hattori's home is a location in The Witcher 3: Wild Hunt.
It's a two floor building belonging to the elven swordsmith Éibhear Hattori, located in the Glory Lane district of Novigrad, west of Putrid Grove.
Originally, it's come across as a home/restaurant, where outside the home are tables with food and customers. However, if Of Swords and Dumplings is completed, it'll transform into that of a forge and Hattori will regularly work out here.
