Free things to do in Tokyo this week

This September, Shimokitazawa welcomes the return of its annual lunar art festival that will coincide with the upcoming autumn moon. Back for its fourth edition, Moon Art Night Shimokita will span several venues in the neighbourhood, including the Shimokita Senrogai Open Space in front of Shimokitazawa Station’s east exit, the rooftop of Higashi-Kitazawa Station, and the Bonus Track complex. Exhibits include an outdoor moon installation by UK artist Luke Jerram, whose giant floating model features striking details of the moon’s surface as captured by Nasa. This particular installation – titled ‘Museum of the Moon’ – is set to be on show every day at the vacant lot of the Shimokita Senrogai complex.  The festival is also hosting London-based artist Nelly Ben Hayoun-Stépanian, whose luminous blue cat inflatables will be on display at the Bonus Track complex. Inspired by the paradoxical Schrödinger’s cat thought experiment, which explores how a cat can be both alive and dead at once, the artist created the cats as a way to spark imagination and explore our relationship with the universe. A new addition this year, Japanese visual artist Takayuki Mori is participating with a three-dimensional installation titled ‘Uranometria’. The work depicts constellation motifs across a celestial dome using ultraviolet-responsive threads, which illuminate the invisible lines that connect the stars in glowing neon colours.

The UNU farmers’ market is one of Tokyo’s longest running and best-attended markets. Taking place every weekend in front of the university’s Aoyama headquarters, this one always attracts a knowledgeable crowd. Organic and local fare is readily available every Saturday and Sunday from 10am to 4pm, with the farmers themselves happy to provide details about their wares. Plus, there's always a few food trucks on hand if you wish to enjoy a quick meal.

Nezu Shrine is not only famous for its 3,000 blooming azalea in spring, the sacred grounds also host the annual Grand Festival, considered as one of Edo’s (as Tokyo used to be known) top celebrations. The festival, formerly named ‘Tenkasai’, started in 1714 under the sixth shogun Tokugawa Ienobu and saw large floats carried through the streets. Nowadays, you can enjoy Sanza-no-mai and Urayasu-no-mai dance performances – both intangible cultural assets of Bunkyo ward – plus a variety of street food stalls. The shrine's main mikoshi (portable shrines) will not be carried out this year, but expect drumming performances by local taiko troupes Nezukoren and Gongen Taiko on September 20 from 11am and 12noon respectively. Sanza-no-mai performances will be held on September 21 from 2pm, and the Urayasu-no-mai performance will be held from 7pm on September 20.

Explore how post-war black markets shaped the evolution of Tokyo’s urban fabric at this intriguing exhibition, held at Takashimaya Archives Tokyo on the fourth floor of the Nihombashi Takashimaya department store. On show until February 23 2026, the display marks 80 years since the end of World War II and focuses on the makeshift marketplaces that emerged amid the ruins of Tokyo. During the war, large-scale demolitions, intended to prevent the spread of fires caused by air raids, created vacant lots across the city. In the chaotic years that followed, these empty spaces, together with bombsites and even roadside corners, were transformed into black markets. Known as yami-ichi, they supplied goods and sustenance in a time of scarcity while seeding new social and commercial hubs. Particular attention is given to Shinjuku, where some of the black markets grew into vibrant entertainment districts that remain central to Tokyo’s identity today. And while most of the markets eventually vanished, their traces endure in the city’s streetscapes and neighbourhoods. Curated by Tokukazu Ishigure of Kwansei Gakuin University, the exhibition reframes black markets as more than unlawful encroachments, highlighting their role as catalysts of urban renewal – spaces where disorder gave rise to energy, resilience and reinvention.
