Company Introduction, Corporate Philosophy and Business Outlook

Connecting People and Things, Creating New Value One Step at a Time

SUN ONE GROUP Co., Ltd. is a company that aims to achieve sustainable growth and create new value by connecting people with one another, people with things, and Japan with the rest of the world.

What we value is not merely pursuing short-term profits, but steadily developing each business while building relationships of trust with our customers, business partners, employees, and society.

As times change, the services required by people in their daily lives and by businesses are becoming increasingly diverse. Making continued use of things, delivering them to those who need them, supporting distribution through logistics, enriching people’s lives, and connecting people with businesses. We believe that each of these initiatives can lead to work that creates value for society.

SUN ONE GROUP aims to begin its business operations with the secondhand musical instrument business as its foundation, then gradually expand its business fields into logistics, real estate, tourism and travel, and human resources-related services while accumulating a track record and experience.

Rather than undertaking everything at once, we first aim to establish a solid foundation in one field, then carry the knowledge, experience, human resources, and trust built with business partners into the next business. This is SUN ONE GROUP’s approach to sustainable corporate growth.

1. Our Starting Point — A New Venture Beginning with Secondhand Musical Instruments

The first pillar of SUN ONE GROUP’s business development is the secondhand musical instrument business, centered on SUN ONE GAKKI Co., Ltd., a group operating company.

Various musical instruments, including pianos, digital pianos, Electones, and guitars, each have their own history and embody the feelings and memories of the people who have played music on them. By appropriately assessing instruments that still retain value and connecting them with their next owners, we aim to contribute to a culture of valuing goods and to the effective use of resources.

Our main activities include the purchase and sale of secondhand musical instruments; imports and exports to and from Japan and overseas markets; product management and storage; maintenance and repairs; painting; and refurbishment and restoration. Through these activities, we aim to enhance the value of each instrument according to its condition and characteristics.

Furthermore, by connecting the commitment to quality cultivated in Japan with the needs of overseas markets, we aim to open up new distribution opportunities that extend beyond Japan’s domestic market and across national borders.

Our goal is not simply to be a company that buys and sells used goods. We aim to identify the value of products, deliver that value to those who need it, and create new opportunities for those products to be used again.

We believe that the experience accumulated through the secondhand musical instrument business—including procurement, appraisal, product management, repairs, imports and exports, sales, and customer service—will become an important management resource supporting the future growth of the entire group.

2. The Corporate Philosophy of SUN ONE GROUP

Building Trust

We believe that trust is the foundation of business activities. Keeping our promises to customers, dealing with business partners sincerely, and striving for transparent business operations are essential. These small, consistent efforts in our daily work lead to long-term partnerships and corporate growth.

Maximizing the Value of Goods

Even goods that are no longer being used may still be needed by someone or may have new ways of being utilized. By accurately assessing product value, carrying out appropriate maintenance and management, and delivering products to markets where they are needed, we work to make effective use of resources and create new value.

Growing Steadily, One Step at a Time

Expanding a business is not simply about increasing its size. It is important to become a company that can continuously provide value while improving quality, services, human resources, and management systems. We will use the experience gained on the front lines to develop each business steadily and reliably.

Contributing to People and Society

Corporate growth takes place within the context of relationships with society. This means providing convenient and reliable services for customers, creating an environment where employees can demonstrate their abilities, developing together with business partners, and promoting exchanges across national and regional boundaries. Through our businesses, we aim to become a company that contributes to people’s lives and society.

3. SUN ONE GROUP’s Strengths and the Business Foundation We Aim to Build

Rather than growing through a single business alone, SUN ONE GROUP aims to make use of the experience and networks gained in each business across the group, thereby strengthening the competitiveness of the group as a whole.

First, we emphasize business operations that prioritize the front lines. From product procurement and appraisal to storage, maintenance, sales, and transportation, we seek to understand actual operations and improve issues at the operational level in order to enhance quality and efficiency.

Second, we take a distribution perspective that connects Japan with overseas markets. While valuing relationships with suppliers and business partners in Japan, we also pay attention to demand in overseas markets and aim to deliver the value of our products and services to a broader market.

Third, we pursue synergies between businesses. The experience in product management and imports and exports gained through the secondhand musical instrument business will form a foundation for a future logistics business. The real estate business can support the securing and effective use of warehouses and business locations, while the tourism and travel business and human resources-related business can create new opportunities to connect people with regions and companies with talent.

Fourth, we emphasize the gradual development of our organization. As we expand our businesses, we prioritize recruiting and developing the necessary personnel, standardizing work procedures, managing quality, complying with laws and regulations, and establishing appropriate management systems. By building systems suited to the scale of each business, we aim to create an organization capable of sustainable growth.

4. Future Business Development

SUN ONE GROUP intends to preserve and strengthen its current business foundation while gradually expanding into additional fields, taking into account the state of preparation in each field, market needs, the personnel required, licensing and permit requirements, and applicable laws and regulations.

STEP 1 | Secondhand Musical Instruments — The Foundation for Group Growth

We will first establish a solid business foundation centered on SUN ONE GAKKI Co., Ltd., covering the purchase and sale of secondhand musical instruments, imports and exports, repairs, painting, refurbishment, and restoration.

We aim to improve our product knowledge and appraisal capabilities, build trusted relationships with suppliers and sales partners, and achieve a stable supply of products and reliable quality management.

The experience and track record gained at this stage will support the future business development of the entire group.

STEP 2 | Logistics — Building Systems That Support the Movement of Goods

By leveraging the experience gained through the secondhand musical instrument business in storage, inventory management, packaging, shipping, and imports and exports, we aim to expand into the logistics field in the future.

We will work to gradually establish the functions required for this business, including warehouse management, product storage, cargo handling, and transportation arrangements, thereby building systems that support the movement of goods.

Rather than viewing logistics merely as transportation, we aim to develop it as an important service that protects product value, facilitates transactions, and supports our customers’ business activities.

STEP 3 | Real Estate — Building a Foundation That Supports Business Activities and Local Communities

As our businesses expand, appropriately securing and effectively utilizing locations such as warehouses, offices, and stores becomes an important aspect of corporate management.

SUN ONE GROUP is considering real estate transactions, leasing, management, and the utilization of commercial properties as potential areas for future business development.

In addition to securing locations required for our own business operations, we aim to explore opportunities to utilize real estate in response to the needs of local communities and businesses, with the goal of creating value for both business activities and society.

STEP 4 | Tourism and Travel — Connecting Japan with the World and People with Regions

Japan has abundant natural beauty, history, culture, food, and unique attractions in each region. We are considering future expansion into tourism and travel, with the aim of increasing opportunities for exchange between Japan and overseas markets.

Through travel planning, related services, and initiatives that highlight the appeal of local areas, we aim to create opportunities for people to experience new cultures and values and deepen their connections with local communities.

When developing this business, we will assess market needs, confirm the necessary registrations, licenses, and permits, and establish an appropriate operational framework before proceeding.

STEP 5 | Human Resources-Related Business — Connecting People with the Potential of Companies

For companies to achieve sustainable growth, they need not only facilities and capital but also the capabilities of the people who work there. Connecting suitable talent with jobs and creating an environment in which people can demonstrate their abilities are important for both businesses and society.

SUN ONE GROUP is considering future expansion into human resources-related fields, with the aim of building systems that connect companies’ personnel needs with the abilities and motivation of workers.

We will consider initiatives that support corporate growth, including recruitment, employee development, retention, and the establishment of effective work systems, while building a human resources foundation that can also contribute to the development of each of our businesses.

The timing of service launches and the specific scope of these businesses will be determined in light of market conditions, organizational readiness, required licenses and permits, and applicable legal requirements.

5. Synergies Across the Group

SUN ONE GROUP’s aim is not simply to operate several businesses side by side. Our goal is to connect the strengths of each business and create greater value across the group as a whole.

The product knowledge and business networks developed through the secondhand musical instrument business can contribute to strengthening logistics capabilities. With logistics functions in place, the storage, delivery, and domestic and international distribution of products can be carried out more smoothly. Cooperation with the real estate field can support the securing and utilization of warehouses and business locations, helping to establish the foundation required for future business expansion.

In addition, the tourism and travel field connects people with regions, while the human resources-related field supports the people needed for companies to grow.

By making use of the experience, information, business relationships, and human resources accumulated in each business throughout the group, we aim to create synergies that would be difficult to achieve through individual businesses alone. This is our long-term goal.

Of course, realizing cooperation between businesses requires appropriate management, clear lines of responsibility, compliance with laws and regulations, consistent quality, and human resources development. SUN ONE GROUP will prioritize establishing a solid foundation and building growth at a sustainable pace.

6. The Future We Aim to Create

Our goal is not simply to expand the scale of our businesses. We aim to become a corporate group that customers choose, business partners trust, employees are proud to work for, and society and international business communities recognize as valuable.

To achieve this, we will improve the quality of our daily operations, respond flexibly to changing market needs, and balance challenges in new fields with continuous improvement in our existing businesses.

We also place importance on using the knowledge and experience gained through our businesses to support future growth and on building a management foundation that earns long-term trust rather than focusing solely on short-term results.

Beginning with one business, carrying the experience gained there into the next, and connecting people and goods, companies and communities, Japan and the world: this is the path to growth envisioned by SUN ONE GROUP.

We will continue to move forward steadily, one step at a time, while approaching the work in front of us with sincerity. By embracing change and continuing to explore new possibilities, we aim to become a corporate group that society needs.
