Nikken Sekkei to Hold “JINNAN MARKET #12” and “JINNAN URBAN SPORTS PARK” on the Same Day, Organized in Collaboration with Local Businesses Under the Theme “Unite”
~Revitalizing underutilized public spaces in the Jinnan area of Shibuya Ward to create new urban value~
Date and Time: October 25 (Sat) – 26 (Sun), 2025, 12:00 PM – 6:00 PM
Location: SHIBUYA KITAYA PARK, Petit Park Street and other nearby roads, SLOTH JINNAN and other nearby facilities

Nikken Sekkei Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director President and CEO: Atsushi Omatsu), as a member of Shibukita Partners, is responsible for planning and managing the community engagement event “JINNAN MARKET” in collaboration with the Shibuya Koen-dori Community Partnership Event Executive Committee, as well as“JINNAN URBAN SPORTS PARK,” will be held simultaneously over two days, October 25 (Sat) through 26 (Sun), in the Jinnan area, including SHIBUYA KITAYA PARK.Now in its 12th edition, JINNAN MARKET, along with the inaugural JINNAN URBAN SPORTS PARK, will expand its scope beyond Kitadani Park to include surrounding street spaces and private facilities, energizing the Jinnan area on a larger scale than ever before.The theme for this year’s JINNAN MARKET is “Unite.” Centered around sports, the event will feature a diverse range of content—including fashion, food, workshops, and live shows—aiming to bring the local community together and create an event that is accessible to everyone.

Currently, urban public spaces face many challenges. In parks, in particular, numerous “prohibitions” have been established due to constraints such as ease of management and cost, restricting users’ freedom and causing these spaces to lose their inherent appeal.
On the other hand, as the population declines and urban structures change, the number of underutilized public spaces is expected to increase. If local residents actively use these spaces as venues for their own activities, this holds great potential for restoring vibrancy and vitality to the community.
In fact, when Nikken Sekkei conducted a social experiment in which users were allowed to freely pursue their desired activities in public spaces, many people expressed a desire for public spaces to serve as “venues for self-expression” and “points of connection with society” through events such as live performances and workshops, revealing the high level of latent demand.Moving forward, a new direction in urban design calls for mechanisms that, through collaboration with local communities, circulate revenue and enable the autonomous and sustainable management of public spaces.

Under the banner of “Social Environment Design,” Nikken Sekkei aims to create vibrant communities and enhance the value of local areas.At Chatan Park, we have been exploring ways to utilize the park through ongoing dialogue with local residents. For the management of Chatan Park, we formed “Shibukita Partners”—a consortium of three companies comprising Tokyu Corporation, CRAZY AD Co., Ltd., and Nikken Sekkei—and have been participating as the designated manager of SHIBUYA KITAYA PARK since 2021.As part of Shibukita Partners, Nikken Sekkei plays a leading role in fostering community collaboration and aims to create new flows of people and relationships through the hosting of JINNAN MARKET.

Now in its 12th year, this event will be held on an expanded scale, including the transformation of roadways around Chatan Park into a market area. Under the theme “Unite,” the event features a wide range of experiential and participatory activities designed to foster a sense of unity throughout the entire Shibuya Ward and Jinnan area through interaction among diverse people. In collaboration with VALLOON, Co Shibuya, and nearby elementary schools, the event will feature workshops enjoyable for both adults and children, as well as activities such as a runway showcasing dance performances. Over the course of two days, we will work together with participants and local residents to liven up the Shibuya and Jinnan areas.

JINNAN Flag Rally (in collaboration with VALLOON) *While supplies last
A workshop-style stamp rally designed to enhance foot traffic in the Jinnan area and create a lively atmosphere over the two days of the event.Participants will visit event venues scattered throughout the Jinnan area, stamp their handkerchief-sized flags with each venue’s unique stamp, and create their very own original JINNAN flag. Let’s liven up these two events with your very own original JINNAN flag, which you’ll create as you explore the town.

Casual Sports Experience (In cooperation with: World Casual Sports Association, Tokyu Corporation) *Saturdays, 12:00 PM–6:00 PM
The World Yuru Sports Association, which develops “Yuru Sports”—new sports that anyone can enjoy regardless of age, gender, or athletic ability—is coming to JINNAN MARKET. We’ll be hosting Yuru Sports events where winning feels great and losing is still fun.With an eye toward developing “Yuru Sports” unique to Jinnan and Chatan Park—where diverse cultures converge—we’ve prepared four events and look forward to seeing you there.

Ema Cheer (In collaboration with Rikkyo University’s Goh Seminar)
This “Ema” project was inspired by JINNAN MARKET’s themes of “Unite” and “Sports.” Centered on “connection” and “support,” participants write what they’d like others to cheer for on their own ema and leave encouraging messages on someone else’s.There will also be a large ema board where you can write messages of support for JINNAN MARKET, fostering connections not only among visitors but also with the event organizers. Let’s send and receive cheers from Jinnan and expand the circle of support.

Shapes of Shibuya · Picture Book Time (in collaboration with co-Shibuya) *Held on Sundays only
At co-Shibuya, a workshop will be held at the Shibuya Ward Child-Rearing Neuvora where participants will use stencils to depict the “shapes” of Shibuya on fabric. Meanwhile, “Picture Book Time”—a storytime event that’s hugely popular at the facility—is coming to Kitatani Park. Why not experience a professional storytime session led by co-Shibuya staff at Kitatani Park?

Basketball Trial Session (in cooperation with TOKYO DIME) *Sundays, 1:00–4:00 p.m.
"TOKYO DIME," a professional 3x3 basketball team based in Shibuya Ward, is hosting a basketball experience session for preschoolers and elementary school students. Why not come and try playing basketball with professional players?

We aim to fully leverage the charm of Shibuya—a hub of diverse culture, including music, fashion, and art—to energize the entire community through sports, and to create a sports event that is accessible to everyone in collaboration with local businesses operating in the Jinnan area.
We will host dance performances by dancers active in the Jinnan area, musical performances by PARK MUSIC participants, and street sports events.

Cheer Flag Gallery (In collaboration with: VALLOON, co-Shibuya, SLOTH JINNAN, and Jinnan Elementary School)
We held a pre-event workshop for fourth-grade students at Jinnan Elementary School and local businesses to create flags supporting the sports event and participating artists. Over 100 support flags created by the students and local businesses will be displayed inside and outside Kitadani Park, adding a splash of color to the streets of Jinnan for two days only.

JINNAN SPORTS RUNWAY (In collaboration with Bunka Gakuen University, FLUSS, and Shibuya Moddy) *Saturdays at 1:00 PM— and 4:30 PM— *30 minutes each
A special event packed with “doing,” “watching,” and “supporting.” This is a fashion and dance sports runway held on Petit Park Street, where cheering flags are displayed.

LET’S PLAY STREET!!, an event held monthly at Yoyogi Park’s BE STAGE where participants can try out various street sports, is expanding beyond BE STAGE to take place on public streets such as Petit Park Street.In addition to the Double Dutch, breaking, freestyle basketball, and freestyle soccer typically featured at LET’S PLAY STREET!!, a special Beyblade experience area will be set up for this event.

JINNAN MARKET has been held 11 times to date, and with each event, it has expanded its venue and attracted a growing number of participants.
Last year, in collaboration with the Shibuya Koen-dori Shopping District Promotion Association—which promotes local community development—we set up pop-up shops on the sidewalks of Koen-dori, the area’s main thoroughfare, and on Petit Koen-dori, successfully utilizing public road space in ways that had not been possible before.These initiatives to utilize street space are also positioned as social experiments aimed at realizing the community development vision set forth by the Shibuya Koen-dori Shopping Street Promotion Association, and JINNAN MARKET has evolved into an event that contributes to future community development in collaboration with local organizations. The number of visitors has been gradually increasing, and the event now attracts a total of over 10,000 visitors over the two days.

In addition, connections among participants facilitated by JINNAN MARKET are growing;for example, a houseplant retailer that had been a regular vendor at JINNAN MARKET leveraged the connections formed in Jinnan through the market when searching for a brick-and-mortar location, ultimately establishing a store near Jinnan—an area where they were already familiar with the customer base. In this way, the event has contributed not only during its duration but also to creating a vibrant local atmosphere on a daily basis.


Based on the increase in the “related population” resulting from the ongoing JINNAN MARKET events and its track record in utilizing public spaces such as streets, Nikken Sekkei has been commissioned since 2024 to plan and operate large-scale events organized by the Shibuya Koen-dori Regional Collaboration Event Executive Committee.By holding these large-scale events on the same day as JINNAN MARKET and collaborating with local art organizations and child-rearing support facilities, we are further energizing the community.
