What happens to exhibition materials when the show ends? Japanese designer Takuto Ohta answers this question with “log x,” a compelling design undertaking. Using about 200 Yoshino cedar logs, originally part of a temporary structure in Nara Prefecture, Ohta gives these logs a second life. He takes them to SKWAT in Kameari, Tokyo, for a two-month creative endeavor.

The art of cutting and experimenting in this design journey
Ohta’s approach was not to start with fixed designs but to let the materials dictate the process. By experimenting with cutting, joining, and assembly techniques, the designer allowed each log to determine its potential form. This immediate, iterative process resulted in about 50 pieces of functional furniture. Even the leftover timber gained new purpose as it became visitor seating or raw material in waiting during the project.

A similar approach to sustainable design can be seen in Hida’s Japanese tableware art, showcasing creativity with natural elements.

From exhibition waste to functional design in this creative process
The pieces retain much of their original mass, celebrating the natural characteristics of the wood. By utilizing the kerfs and varying dimensions left over from their initial use, Ohta transforms them into diverse forms like stools, benches, and tables. The project focuses on ‘decomposition’ and ‘production’, exploring how materials can be reimagined and reused after their original purpose in this undertaking.

In this way, “log x” embodies a sustainable philosophy. While many exhibitions build structures with short lifespans, Ohta sees dismantling as a stepping stone to new design possibilities. The once-temporary logs evolve into a working library of materials and eventually a unified collection of furniture, demonstrating that ‘temporary’ doesn’t mean ‘disposable’. This initiative helps illustrate that point.



The collection reflects Ohta’s commitment to experimentation. From their initial role in a temporary exhibition, the cedar logs undergo a transformation, becoming various furniture pieces that capture the imagination and highlight the potential of reused materials in this exploration.

The name “log x” symbolizes this dynamic process where logs are variables transformed by creative methodology. On display at SKWAT in Tokyo, this project invites viewers to see the potential in what might otherwise be discarded.
