Reuse to create new value
Our company aims to adapt an environmentally friendly, recycling-oriented society and is developing a business centered on the reuse of computers.
We have built a one-stop system in which we handle everything from product receipt to cleaning, inspection, packaging, and shipping in-house, achieving both high quality and efficiency.
We sell used computers and peripherals at major domestic e-commerce malls such as Rakuten Market, Amazon, and au PAY Market.

Message
To prepare for a second founding
The power to create the future is in our hands.
In 2012, I founded Ryonan International Trading Co., Ltd. in Japan, with the desire to challenge to the world as a child in my heart.
What started as a small challenge by just one person has now grown into a company with sales of 1.7 billion yen, and has evolved into a company that is needed by society while remaining debt-free until 2025.
We would like to express our sincere gratitude to everyone who has supported us in this journey.
But our story is just the beginning.
Now, 13 years after its founding, Ryonan International Shoji declares its "second founding."
This is a new determination as a company to create the future with our own hands without fearing change.
At the heart of this determination is our new management philosophy
``To be a company that is chosen by both customers and employees.''
This philosophy was born in response to simple questions from our employees.
“Where is this company headed?”
“Can I grow here?”
“Is it a company you can be proud of?”
As the President, I want to respond clearly to each of them.
This idea is reflected in this philosophy.
With our second founding declaration, we will steadily move forward from being a ``growing company'' to ``becoming a company chosen by both customers and employees.'' Our goal is to become a 10 billion yen company in the near future.
To achieve this, we will need to strengthen our corporate sales, expand our data erasure business, create rental and maintenance services, and develop sales strategies that utilize AI, as well as take on the challenge of creating new business models with ideas that go beyond traditional business models.
Additionally, in order to develop personnel who can take on challenges and adapt to any changes in the environment, we will reform the human resources system, expand our bases, and renew our IT infrastructure as part of our company's basic strength.
These are all investments that will help create a company where each and every employee can create greater value and work with pride.
Our refurbishment business is more than just refurbishing used PCs.
it is,
- Creating a circulation system that connects resources to the future
- Realizing a society where everyone has access to IT
- Cultivating a culture in which workers can be proud of
This is true value creation for society.
Ryonan International Shoji will continue to be a company that improves society through its business and allows its employees to work with pride.
Now that we have entered our second founding, we are stepping into a new stage.
The power to create the future lies within ourselves.
We sincerely ask for your continued support.
Auspicious day in January 2026
