DEVISER CO., LTD.

COMPANY OVERVIEWABOUT US
Our history goes back to 1977 when our founder Kei Yatsuzuka established the manufacturing
plant Hedaway inc, along with a guitar builder Yasuo Momose, who was already renowned forhis superb technique in guitar building. They started the acoustic guitar brand Headway sharing
the same ambition to create acoustic guitars of the highest quality.
In 1991, Deviser Co Ltd. was established as a sales and development division independent fromDeviser Technical Center (completed in 2024)
A Momose brand guitar madeusing Japanese wood materialsHeadway Inc. for more than 30 years after that, we have been working hand in hand with thefactory to take our high-quality guitars to the player. Today, the Headway Inc. workshop has beenrenamed to “Aska workshop”, and it strives to maintain Yasuo Momose’s ideals by passionately
working on the production of high-quality, handmade guitars to the best of the craftsmen's ability.
On the other hand, in order to bring our guitar-making philosophy to a wider audience, we began
partnerships with selected OEM factories in the 1990s, providing technical guidance andexpanding production volume. From these partnerships, we expanded our horizons anddeveloped multiple all-new entry-level series for Bacchus, one of our electric guitars and basses
brands.
In the 2000s, we also developed and nurtured many other brands with different concepts such as
Momose, a high-end brand named after the master builder Momose himself; STR; andSeventySeven, a Hollowbody series.
Since the beginning of the 2010s, we have continued to develop unique instruments in terms ofboth appearance and sound, using Japanese wood materials such as Sakura (Japanese Cherrywood), which has become our most popular product line through displays at shows.
Today, with the philosophy that has guided us since our founding, we continue to hone our craft
every day, aiming to deliver guitars that will be loved by a wide variety of users, from the entry
class to professional artists.

pieces were produced in a short production period fromApril 2005 to January 2007. The brand was born from avery small custom-made project.
After the end of production, the brand gradually became
more and more popular among enthusiasts, and many
requests were received for its resumption. In 2021, toROSETTA VESSELJapanese Collection SP22commemorate the 30th anniversary of the founding ofDeviser, the "Deviser Special Specification" brand wasbrought back in response to users' requests. This brand willcontinue to grow and evolve step by step.

Looking back at the path taken by Deviser regarding
Sakura wood, it all started in 2014. At the time, we were notyet familiar with cherry blossom tree wood, or “Sakura”
wood as a material for guitar-making, and making aninstrument out of Sakura was a challenge. After much trialand error, the first Sakura model we produced was actuallya ukulele, not a guitar. It was a very important choice and afateful coincidence for us to make a ukulele using theSakura wood that the Japanese nation have loved sinceancient times. We have been working with Sakura for 8years, and we can see the infinite possibilities the materialhas. -SAKURA UKULELE-, a new brand specializing in
Sakura wood, and which is neither Headway nor Momose
but its own brand, was launched in the spring of 2023
