Faithfully output player's sensitivity and energy | Shior Kai-B4, B5 | Yama Gakki Japan


Thank you for using Yama instruments.
Decades have passed since establishing an electric guitar production company.
I am grateful that it is the result of the support of many people.
Right now we are focusing on the guitar neck and body OEM production.
Nine years have passed since I sold products online.
I decided to develop and produce an original bass guitar.
Shiojiri Asao with high technology and experience will decide to develop and produce its own bass guitar.
It is not a smooth process until completion, but the biggest problem is to "create a convincing sound".
Repeated trial and error, dissatisfied days passed.
In such a case, we cooperated with Yuka Shimizu to create a "Shior" original that we can recommend to our customers with peace of mind.
Please try by all means. Please listen.
From now on we will continue to make even more efforts with the motto "Production of products that customers can last long".
And I would like to express my deep appreciation to the many people who helped Shior complete it.
