Your innovative approach to the sushi counter design at Tsukiji Sushiiwa Tsukijiten Sushi Restaurant, particularly the adjusted floor height for shared viewing perspectives between chef and customers, represents a profound understanding of traditional sushi culture - could you elaborate on how this spatial design decision enhances the dining experience and preserves Edomae sushi traditions?

Edomae sushi was originally eaten standing at street corner stalls, but as time went on, restaurants began to pursue more sophisticated equipment and customer comfort. However, in order to pass on the tradition, the essence remains the same: serving customers with high-quality sushi and making them happy.Therefore, the challenge for this project was to integrate and design equipment that could manage and provide high-quality sushi, support the chef's behavior and staff response, and create a space where customers could spend a comfortable time.Among the challenges, adjusting the height of the viewpoints of customers, chefs, and staff was an important issue. This is because in Japan, respect and hospitality towards guests is based on the idea of ​​communicating and responding in a way that suits the guest, and when a customer is seated in a tatami room, the staff sit at eye level so that they can communicate and respond accordingly. We will take action.Based on these ideas and customs, we have developed technical solutions such as waterproofing the chef's kitchen floor and installing drainage pipes so that the chef can serve customers comfortably while seated at the sushi counter at eye level. Above, we adjusted and raised the floor level on the customer side.The design of this project is not a decoration or statement, but rather a design that subconsciously enables traditional thoughts and behaviors and allows them to be inherited.

The integration of highly transparent, frameless glass showcases at Tsukiji Sushiiwa Tsukijiten Sushi Restaurant creates an unobtrusive yet functional display solution - what inspired this specific design choice, and how does it contribute to the restaurant's goal of highlighting the chef's craftsmanship and fresh ingredients?

Even in Japan, it is common for sushi restaurants to use a glass showcase with refrigerant pipes in a strong stainless steel frame placed on the counter. On the other hand, privately owned sushi restaurants store seafood along with ice in old-fashioned wooden boxes, and there is no functional problem in managing seafood ingredients.However, this project also gave high priority to the customer's perspective. As a result, a specially designed, highly transparent frameless glass showcase was integrated into a cohesive and intimate sushi counter that eliminates noise from the customer's view.

In designing Tsukiji Sushiiwa Tsukijiten Sushi Restaurant, you worked with specialized craftsmen for Hinoki wood, plastering, masonry, and Japanese paper - how did these collaborations with traditional artisans influence the final aesthetic and functionality of the space?

The texture created by each material and the finishing techniques of the craftsmen is extremely excellent, and the space has been integrated with modern equipment to create a one-of-a-kind space. This sophisticated space plays an important role in guaranteeing the authenticity of the Edomae sushi served at this restaurant.

The research phase for Tsukiji Sushiiwa Tsukijiten Sushi Restaurant involved extensive prototyping of the customer-chef relationship - could you share specific insights from this process that led to breakthrough moments in the design development?

First, it was important to share with the client the historical evolution of Edomae sushi and what kind of restaurant style would be appropriate for the future.The actual staff etiquette and facility equipment were complex, but through prototyping we discovered that rather than dealing with them in a complicated way, we could simplify them and have a higher possibility of tolerance. Ta.The discoveries we made during this process about the chef's behavior at the sushi counter and the customer's perspective were extremely helpful in the specific design stage, including selecting materials, setting dimensions, and lighting plans.

Considering Tsukiji Sushiiwa Tsukijiten Sushi Restaurant's location near the former central fish market, how did this historic context influence your design decisions in creating a space that bridges traditional sushi culture with contemporary dining expectations?

Tsukiji Sushiiwa was located close to the former Tokyo Central Fish Market, and was also located right in front of the historic Tsukiji Honganji Temple.However, no one could have predicted what the cityscape would look like after the Tokyo Central Fish Market was relocated for the Tokyo Olympics 2020.Based on this historical trend, this project also aimed to pass on the townscape of the Tsukiji area to the future. Plastered walls, window lattices, and Japanese paper shoji screens were adopted as landscape elements for the townscape that will be inherited.

The versatile layout of Tsukiji Sushiiwa Tsukijiten Sushi Restaurant, incorporating both counter seating and tatami rooms, presents an interesting balance - what were the key considerations in designing these distinct dining spaces while maintaining a cohesive atmosphere?

In fact, the tatami room is often used for business meetings and families, so it was necessary to create a private and quiet space. On the other hand, the counter seats needed to be an intimate and open space where people could enjoy interaction with the chef and the customers at the counter, and the table seats needed to be a casual space where visitors could feel at ease.When designing this space, it was important to create a well-balanced layout that would allow each customer to enjoy sushi in their own diverse styles.In addition, since the staff will respond to each customer's purpose and sitting style, it was important to have a functional design that would not cause stress or waste to the staff.

Your focus on maximizing the visibility of fresh seafood and chef's skills at Tsukiji Sushiiwa Tsukijiten Sushi Restaurant reflects a deep understanding of Edomae sushi essence - how did you translate this philosophical approach into specific design elements?

While it is important for the sushi counter to showcase the fresh seafood and the chef's skills, it was most important to design a sushi counter that integrates into a space that makes the customers feel like one.In order to achieve these goals, I tried to provide sufficient functionality and eliminate waste. This meant focusing on carefully selected materials and thoughtful dimensional design.In addition, a proper lighting plan was essential. Like the stage where actors or dancers perform, like the glass cases in jewelry shops and patisseries that display jewelry and chocolates, and so that the audience can enjoy a comfortable time... It was designed with the underlying philosophy in mind.

The completion of Tsukiji Sushiiwa Tsukijiten Sushi Restaurant in 2007 marked an important milestone in restaurant design - looking back, which aspects of the design have proven most successful in fostering the intended interaction between chefs and diners?

Even in Japan, there are many sushi restaurants that are efficient in terms of management and convenient for cooking, but there are not many that are well-balanced and integrated with customer comfort in mind.I believe the secret to my success is my design method, which involves first sharing the challenges faced by the chef, diner, and customer, and then carefully solving each problem one by one through design.

As the recipient of an A' Design Award for Tsukiji Sushiiwa Tsukijiten Sushi Restaurant, how do you see this recognition influencing the future of traditional Japanese restaurant design in an increasingly global culinary landscape?

Although Japanese cuisine was born from ingredients and cooking methods that are unique to Japan, I believe that a flexible approach to ingredients and cooking methods will remain effective even as we develop globally.In the design field as well, I believe that essential designs that flexibly solve and integrate situations and problems will be needed in the future, rather than sticking to traditional styles.

The careful consideration of noise reduction and visual clarity at Tsukiji Sushiiwa Tsukijiten Sushi Restaurant demonstrates exceptional attention to detail - could you share some of the less obvious design solutions that contribute to the overall dining experience?

To achieve visual clarity, I simplified the components and organized the functionality.To give you an easy-to-understand example, I designed a box for storing seafood, a box for seaweed, and cooking utensils such as cutting boards all made of hinoki cypress, the same material used for sushi counters.I also arranged for cooking that is not directly related to nigiri sushi to be done in the backyard kitchen.It was also important to design effective lighting so that each element would have an appropriate presence on the sushi stage.
