The common space of the Toda Building will be used as a venue for forward-looking public art, offering emerging artists and curators opportunities to present large-scale works that engage with the urban landscape. APK Public is a public art program that enriches the ways people live and work, allowing visitors and office workers to engage with artworks on a daily basis, and aiming to stimulate creativity and expand perspectives. 

In this first exhibition, we welcome Iida Shihoko, an internationally curator, who presents works based on the concept of “Helix―Speculating on Infinite Possibilities,” an effort to transform the stagnation of uncertain times into a positive outlook for the future.

With the helix as a new symbol of the Toda Building, artists present works on this theme, characterized by spiral structure, rotation, circulation, sequential connection, pendulum movement, and sustainability that represent the mobility, movement, and flexibility of people who gather in the building, while at the same time evoking aspirations toward upward mobility and sustainability with eyes on the future.

ONOZAWA Shun
Performing structure

Six stainless-steel balls swing back and forth like pendulums at a constant speed, each at a pace differing subtly from the others. Their movements, influenced by inertia, gravity, and external conditions, have the potential to lead to unexpected collisions. With a background as a professional juggling performer, Onozawa applies the skills of controlling gravity and centrifugal force through physical sensation to a system that interprets signals and responds automatically. His goal is to orchestrate a live performance in which the laws of nature, computer technology, and human skill converge.

Approx. 8 min. | Performances run hourly from 11:00 am until 7:00 pm　

ONOZAWA Shun
Onozawa Shun was born in 1996 in Gunma. He creates performative sculptures that originate with physical sensations he has experienced as a juggling performer. Onozawa completed his graduate studies at the Department of Intermedia Art of Tokyo University of the Arts, and has participated in exhibitions including Media Ambition Tokyo (Shibuya Scramble Square, 2020 / Mori Arts Center Gallery, 2021) and Aichi Triennale 2022: STILL ALIVE. In 2021, he was selected as one of the “Forbes Japan 30 under 30.”

NODA Sachie

flower

Noda produced this series during the two years preceding the completion of the Toda Building, drawing on fieldwork conducted eight times throughout the four seasons in the Kyobashi area. She collected seasonal plants along roadsides and at construction sites and dried or reduced them to extract their unique characteristics, shaping them into new forms while reflecting on urban narratives encountered during the fieldwork. This series illuminates the life cycle of organic matter, from growth to decay, and changes caused by human inhabitation of the area. It also sheds light on often-unseen characteristics of the terrain and soil, manifesting the urban ecosystem in condensed form.

NODA Sachie
Noda Sachie was born in 1978 in Shiga Prefecture. In addition to painting, she is involved with plants through her family’s business, the flower shop Hananoen. She engages with plants during daily life and her works deal with landscape. She explores the sense of things as a cycle, mainly including spatial installations in which she arranges natural elements, plant-based works emerging from her activities, and garden design. In recent years, she has exhibited works including sculptures and paintings of plants based on her life’s work at various venues, and has also engaged in creative and performance projects involving gardens and other spaces. She was awarded the top prize at the Artists’ Fair Kyoto 2021 Akatsuki Art Awards. Her recent solo exhibitions include A Pure Place (Mizuma Art Gallery, 2024).

For this work, Mohri drew inspiration from the Model Showing the Motion of an Earth Particle during Earthquake (collection of the National Museum of Nature and Science). This model, which uses wire to render the earth’s movements visible in three dimensions, is based on records of an earthquake that struck Tokyo on January 15, 1887, documented by pioneering seismologist Dr. Sekiya Seikei  (1854–1896). While Mohri’s work appears to be a static sculpture, departing from the kinetic art for which she is known, in its reference to a seismologist’s model that embodies the kinetic energy of the Earth’s motion, it is an extension of her previous practice. Exhibited in a building equipped with cutting-edge seismic isolation technology, it represents the ceaseless negotiation between people and the natural environment.

MOHRI Yuko
In her installation and sculpture, Mohri works not to compose (or construct) but to call attention to “event” that constantly shift according to various conditions such as the environment. Exhibitions include Jam Session: The Ishibashi Foundation Collection × MOHRI Yuko–On Physis at the Artizon Museum (2024–2025), Compose at the Japan Pavilion, 60th Venice Biennale, solo exhibitions at Camden Arts Centre (London, 2018) and Towada Art Center (Aomori, 2018–2019), and participation in international exhibitions such as the 14th Gwangju Biennale (2023), the 23rd Biennale of Sydney (2022), and the 34th São Paulo Biennale (2021).

MOCHIDA Atsuko
Steps (Entrance lobby)
Steps (Square)

Steps, a spiral staircase hanging from the entrance lobby’s ceiling, manifests trajectories that Mochida mapped in three-dimensional space. Liberated from the practical function of facilitating human movement, the staircase becomes a twisting, overlapping sculptural intervention in the space. Its delicate curvatures and dynamic form change depending on the viewing angle (from below, the side, or above), introducing changes to the building’s interior space depending on the season and time of day. In the outdoor square, another installation also titled Steps ascends from the ground, echoing and corresponding to the indoor work.

MOCHIDA Atsuko
Mochida Atsuko was born in 1989 in Tokyo, and lives and works in Nagano. She obtained master’s degrees from Bauhaus University, Weimar and Tokyo University of the Arts in 2018. In 2018 and 2019, she carried out research in Germany and Singapore on a grant from the Pola Art Foundation. She specializes in transforming the meanings and qualities of spaces by inserting temporary foreign elements such as walls and staircases into existing spaces and buildings, introducing uncertainty to the boundaries between private and public. Her recent projects include Unbuilding (Iida City, Nagano, 2021-2023), which transformed the process of demolishing a house into a work of art.
