Shokz Japan Co., Ltd., a manufacturer of open-ear earphones that provides a new audio experience, is pleased to announce that Mr. Ichiro Yamaguchi of Sakanaction, who is active as a musician, has been appointed as the brand ambassador of Shokz Japan.

To commemorate this appointment, under the supervision of Ichiro Yamaguchi, we have jointly produced the “OpenFit 2+ Ichiro Yamaguchi Model”, which incorporates our unique perspective and worldview to the point of forgetting it.

Additionally, as the first collaboration commemorative project, we will be running a giveaway campaign where you can win items signed by Ichiro Yamaguchi. Furthermore, as a second step, we will develop the project in stages, such as by lottery selling a special box of 300 limited sets containing the same model.

Yamaguchi, who made his major debut with Sakanaction in 2007, has always continued to explore new expressions and possibilities while taking music seriously.

Even before becoming a brand ambassador, Mr. Yamaguchi has been using Shokz open-ear earphones as his daily companion from morning until night, and sometimes until the moment he falls asleep.

First of all, Shokz has decided to welcome Mr. Yamaguchi as a brand ambassador, empathizing with Mr. Yamaguchi’s challenging attitude and deep understanding of the new value of open years.

Shokz will be developing a collaboration commemorative project to welcome Ichiro Yamaguchi as a brand ambassador. This project will implement the following three final steps in stages.

This project is unique in that it goes beyond an unconscious campaign and product launch, and reflects Yamaguchi’s background and values ​​to the limits of product design and visual expression.

As a special feature, this collaboration model, “OpenFit 2+ Ichiro Yamaguchi Model”, has a special design inside the earphone case.

“There’s no going back. It’s just something that’s going to happen.”

Engraved with the message (not to return to the original, but to become new)These words symbolize a new determination that Yamaguchi has been thinking about while restarting his activities as Sakanaction after a period of medical treatment.

It was also adopted as a design motif.Numbering “0106” is “ichi (1), low (6)”It is a play on words that symbolizes Mr. Yamaguchi’s pronunciation, and it is an element that gives a sense of playfulness.

【Features】

Inside the earphone case,

It is engraved with the message, “There is no going back, only becoming what is to come.” (Not going back, but becoming new).
These words are a phrase that symbolizes the new determination that Yamaguchi came up with while restarting his activities as Sakanaction after a period of recuperation from depression, and are also a message that symbolizes this collaboration.

On the earphone itself, it reads “ichi (1), ro (6) -”, which is a playful word play that is typical of him. At first glance, it looks like an inorganic industrial product, but it is imbued with a responsibility to “deliver something with my name on it” and a secret message to the fans.

In this collaboration, we designed not only the product but also the entire experience as a single work. Under the supervision of Ichiro Yamaguchi, we have prepared a limited edition special box designed from scratch for this project, from box design to packaging configuration.

This box has a hologram number sticker engraved with “0106-XXX”. Each of the 300 sets from around the world is given a different number, making it a collector’s item that can be enjoyed as a one-of-a-kind special box.
