As part of the Christmas campaign at "Tokyu Plaza Ginza," an installation called "KIRIKO TREE" was created, taking Edo Kiriko glassware as its motif, in a corner of Sukiyabashi Intersection. The tree is adorned with a new Edo Kiriko pattern developed in collaboration with artisans.

Edo Kiriko is a traditional craft that represents Tokyo. In recent years, as the shortage of successors has become more serious, young artisans have been at the forefront, creating new patterns and techniques one after another. However, these innovations have had low awareness and limited platforms for dissemination. Tokyu Plaza Ginza was one of the places in Tokyo, where Edo Kiriko was born, to showcase the works of artisans, but due to the COVID-19 pandemic, the opportunities for such events had decreased. To regain the opportunity for dissemination and to convey the thoughts and challenges of the artisans, an opportunity was created for people passing through the streets associated with Edo Kiriko to have a chance to experience and engage with Edo Kiriko.

In order to make the new Edo Kiriko patterns feel familiar to people passing by, we incorporated the history and streetscape of Ginza as inspiration. As a method of expression, we decided to utilize light and shadow, taking a cue from the perspective that artisans value when designing patterns, which is to "carve light."

To blend the Western culture of Christmas trees with Japanese Edo Kiriko, we illuminated the installation with lights reminiscent of traditional Japanese "Andon" lanterns. By adding movement to the interplay of light and shadow, we created overlapping patterns and variations in shape, resulting in the emergence of new cut-glass patterns within the space. These elements represent the artisan's process of combining technique and pattern design to create new patterns.

Furthermore, to convey the atmosphere of the workshop, we incorporated environmental sounds such as the sound of glass being cut, clashing noises, and cleaning sounds as background music for the display.

The KIRIKO TREE was not disposed of after the end of its exhibition period but was instead reinstalled as interior lighting within Tokyu Plaza Ginza, continuing to convey the allure of Edo Kiriko to visitors. By utilizing light and shadow in the presentation, the number of electrical decorations was minimized compared to traditional illuminations, allowing for a dynamic display while minimizing power consumption. Additionally, through captions and videos showcasing the artisans and their workshops, the installation regained opportunities for dissemination.

Furthermore, by collaborating with the store "Fujimaki Department Store" within Tokyu Plaza Ginza, visitors were able to purchase the works of the artisans, contributing to increased sales for each workshop and creating a sustainable cycle centered around the installation.
