Mitsui Fudosan launches smartphone indoor-navigation service across its Nihombashi retail cluster
Mitsui Fudosan began running a smartphone-based indoor-navigation service across six of its tenanted buildings around Nihombashi Station on October 1, a concrete fix for the wayfinding problem that dogs underground retail districts — and, with pre-launch testers reporting a 100 per cent arrival rate, an accessibility bet Japan's largest commercial-property developer is now extending toward Tokyo Station.

Mitsui Fudosan said it began operating "IndoorFlow," a smartphone indoor-navigation service developed with Ashirase, a startup spun out of Honda, across six of its tenanted buildings around Nihombashi Station from October 1: COREDO Muromachi 1, 2, 3 and Terrace, Nihombashi Mitsui Tower, and YUITO, according to the developer's October 2 announcement.
