This is certainly exciting for me, as a resident of Ikebukuro: the main Muji store in Ikebukuro (which I believe was actually the first Muji store) is undergoing some major renovations, and it’s going to be turned into a new flagship store (although it certainly won’t be as massive as the Yurakucho one). They will be celebrating with exhibitions, and a series of talk events, everything kicking off September 18. Note that Ikebukuro is still home to the Muji corporate HQ.
