Who we are

Established : 1978
Employees : 265

Our company, SUCCESS Corporation, is situated in Tokyo and was founded in 1978. On June 7th of this year, we celebrated our 44th year in operation. Our capital is 100 million JPY.

Our Motto

Make what you want to make, Make what stands out, Do it now.


Our management is based on the following principles.

(1) Our mission is to create a new culture by software development.
(2) We will expand our corporate value by continuous development and transformation.
(3) We aim to provide innovative systems, as well as exciting items and satisfying services.


01 Work is something we create for ourselves, not something provided to us by others.
02 We do not point out flaws, instead we provide suggestions to solve the problem.
03 When people stop learning, they grow old; some elderly people live like they are 20 years old, while some other young people live like they are 80 years old. You may leave the company quietly if you consider yourself “old”.
04 Plan it out before you start working. Everything is determined by prioritization.
05 Better being “rough and ready” than “slow and elaborate”.
06 Punctuality builds trust; make it a habit to arrive five minutes early.
07 Lack of communication is the root of all problems. Remember the names of the people you meet, and always greet them. Also, make sure your directions/requests are clear and well-understood, and make a habit of sharing information.
