Ideas, made real.

A software house built on skill and ingenuity.
About us
We’ve always built things that we wished existed, and we bring the same level of craftsmanship to our work for clients.
Founded as a sole proprietorship in 2001, we incorporated in 2006. We are based in Nishinomiya, between Osaka and Kobe.
Our name, dotAster, comes from the string of characters “.*” (a dot and an asterisk), which matches any string in computing.
It embodies our belief that any idea can be realized.
