With its theme, “City as Garden,” this year’s T3 Photo Festival invites us to metaphorically stop and smell the roses — and refresh our appreciation of urban life along the way.

The annual festival runs until Oct. 27 in Tokyo’s Yaesu, Ginza, Nihonbashi and Kyobashi districts, across 15 locations — or “gardens,” as they’re called in T3’s official statement. The garden idea refers to the scattering of exhibits among office buildings and shops, and is partly an expression of optimism about greener urban design and ecological consciousness.

Without a large gallery or museum space as its venue, T3 makes a virtue of necessity; the festival is part treasure hunt, part intervention. In addition to gallery spaces, photo exhibits have sprouted in office building lobbies, alleyways and shopping areas. As festival founder and director Ihiro Hayami puts it, “The artists are seeds, providing something new to disrupt our routine.”
