Japanese Education Philosophy: OJT and Kaizen in Corporate Training

When considering Japan’s position in the global economy, the success of dozens of brands such as Toyota, Sony, Honda, and Panasonic immediately comes to mind. So what has kept these companies ahead of their competitors for decades? Is it technology, capital, or market size? At the core of the sustainable success of Japanese companies lies a deeply rooted corporate training and development philosophy that treats “investment in people” not as a campaign but as a system. This philosophy sees employees not as “capacity” but as “developable potential” and designs training not as a one-time event but as a permanent mechanism embedded within the organization.

In this article, we examine in detail the four educational philosophies that form the foundation of Japanese companies and how these approaches are integrated into corporate training processes. Then, we share what the collaboration between Gakken Turkey and Astera Human Resources, which brings this philosophy to Turkey, means for organizations.

What is Gakken? An 80-Year Global Education Legacy

Gakken Holdings was founded in 1946 in Japan by Hideto Furuoka and operates globally in the field of corporate training and human development. In a country devastated after World War II, Furuoka saw education as the only way to rebuild society and established Gakken Kenkyusha with this vision.

Today, with a presence in more than 17 countries, over 110 group companies, and more than 29,000 employees, Gakken offers a broad learning ecosystem ranging from early childhood education to professional development. With net sales of 185.6 billion yen, it is not only an educational institution but also a real corporate training practitioner managing an organization of over 30,000 employees.

Gakken’s founding philosophy is built on two core principles: “Creating something out of nothing” and “Working for humanity and the world.” These principles continue to guide the work of Gakken Turkey in the field of corporate training today.

Gakken Turkey: Bringing the Japanese Education Approach to Turkey

Gakken Turkey was established in 2022 with the vision of combining the Japanese education approach with Turkey’s local realities, operating in the field of corporate training and human development. The company’s core promise is clear: not one-time courses, but building a human development system that lives permanently within the organization. This system operates through a three-stage process:

• Company Needs Discovery: The company’s challenges are deeply analyzed and a tailored program is designed.
• Optimal Capability Design: The most appropriate competency design is created; instead of one-size-fits-all, customized solutions are developed.
• On-site Implementation: Training is embedded into the organization through on-site application and made sustainable.

Four key elements distinguish Gakken Turkey from other training providers: a system approach that builds mechanisms rather than just content, a strong focus on field and organizational capability from Japan, a long-term investment philosophy that prioritizes human development, and strong localization capability aligned with Turkey’s cultural context.

Four Core Japanese Philosophies: A System Beyond Training

At the core of Gakken Turkey’s corporate training approach lie four philosophies that have been tested for decades by Japanese companies and form the basis of their global success. These philosophies are not offered as “standard packages” but are embedded into organizations through need discovery, tailored design, and on-site implementation.

1. OJT (On-the-Job Training): Developing People Within Real Work

OJT is one of the fundamental pillars of Japanese management culture and a model where corporate training is most strongly integrated into daily operations. The concept is simple yet powerful: training takes place not in classrooms but within the actual work environment. Senior employees transfer knowledge and experience to junior professionals within daily workflows.

The strength of this approach comes from the integration of learning with real application. The gap between theoretical knowledge and field experience disappears; new employees learn not only “what to do” but also “why and how to do it” within the organization’s context. Additionally, OJT transforms corporate training into a systematic structure rather than a person-dependent process.

In many companies in Turkey, onboarding is limited to a few days of presentations and documentation. The OJT approach transforms this process from a “starting activity” into a continuous development mechanism.

2. Rank-based (Development by Role and Level)

In Japanese companies, there is no concept of “providing the same training to everyone.” Instead, the right expectations and competency design are created according to each employee’s career planning stage. This approach ensures maximum efficiency in corporate training processes.

The rank-based approach recognizes that the behaviors and competencies expected from a new employee are fundamentally different from those expected from a mid-level manager or a senior leader. Therefore, training content, methods, and evaluation criteria are also differentiated accordingly.

This philosophy also forms the foundation of Gakken Insight Academy’s four-layer program structure: Executive Level, Management Level, Professional Level, and Foundation Level. Each layer focuses on the specific behaviors expected from employees at that level.

The commonly used “general training day” approach in many companies in Turkey—where all levels attend the same session—is completely contrary to this philosophy. The rank-based approach ensures that every unit of training investment creates maximum impact.

3. Kaizen: Creating a Culture of Continuous Improvement

Kaizen is derived from the Japanese words “Kai” (change) and “Zen” (better), meaning continuous improvement. However, seeing Kaizen merely as a “management tool” would be misleading; Kaizen is a culture, and it becomes sustainable when supported by corporate training processes.

In this culture, improvement is not only the responsibility of management or the quality department. Problem-solving becomes a natural part of daily work, and employees at all levels are responsible for questioning existing processes and proposing better alternatives. This mindset is systematically developed through corporate training. The core principles of Kaizen include:

• Continuous improvement mindset: progressing with small but consistent steps
• Active participation of all employees in processes
• Eliminating waste and inefficiencies
• Decisions focused on productivity and efficiency
• Fast and flexible decision-making mechanisms
• Continuous investment in training and development

Gakken Turkey does not limit the Kaizen culture to the manufacturing sector. It also aims to embed the continuous improvement mindset in white-collar work environments. Additionally, 5S (Sort, Set in order, Shine, Standardize, Sustain) practices are offered as the physical reflection of Kaizen culture in the workplace.

4. Foundation: Building a Common Language of Work

The fourth and perhaps least known but most critical philosophy is Foundation. Foundation ensures that employees think, work, and communicate in a consistent way to produce stable results within the corporate culture. This structure forms the backbone of corporate training programs.

This does not mean employees lose their individuality. On the contrary, it means developing a shared “business language” within the organization. A common framework is established for how decisions are made in meetings, how information is shared, how reports are structured, and how problems are addressed. These standards are disseminated across the organization through corporate training.

One of the most well-known elements of this shared language in Japanese business culture is the HOURENSOU approach: Houkoku (reporting), Renraku (informing), and Soudan (consulting). These three steps ensure that information flow becomes systematic rather than person-dependent.

In many organizations in Turkey, issues such as “misalignment due to unstructured information sharing” or “meetings that take too long without producing decisions” are common. The Foundation philosophy addresses exactly these root problems.

Pre-Test / Post-Test: A Measurable Training Experience

An important element that complements these four philosophies is Gakken Turkey’s principle of measurability. This approach ensures that corporate training processes produce tangible outcomes. Before each program, participants’ current levels are clearly defined through pre-tests and needs analysis. After training, development is measured through post-tests and application results. The Kirkpatrick 4-level evaluation model (Reaction, Learning, Behavior, Results) is applied.

The reports provided to organizations reveal both individual assessments and overall development areas within the company. In this way, training becomes not just an activity that “feels good,” but a measurable development output within the organization.

Gakken Insight Academy: Four-Tier Development Programs

Gakken Insight Academy structures corporate training programs for all organizational levels into four tiers. This structure aims to systematically develop competencies appropriate to each employee’s role and level of responsibility. At the same time, it creates a shared development language across the organization, strengthening the link between individual performance and corporate goals.

Executive Level

The executive coaching program aims to make behavioral change sustainable through a 3-month one-on-one coaching process. The program follows a cycle of “Pre-Task Design → Real Work Application → Structured Reflection.” Target profiles include leaders who deliver results but strain their teams, and those seeking a higher leadership perspective.

Management Level

The 5-day leadership program (delivered monthly over 5 months), leadership training, and coaching training are included at this level. Leadership is addressed in three dimensions: Leading Self, Leading Others, and Leading the Business. In coaching training, the Japanese management principle that “developing employees is the most important responsibility of every manager” is emphasized.

Professional Level

Core business skills such as logical thinking and problem-solving, data-driven thinking, innovation, presentation techniques, and improving customer satisfaction are covered at this level. Each program is enriched with practical design and case studies aligned with global company standards, aiming to directly impact business outcomes through corporate training.

Foundation Level

Time management, effective communication, proactive behavior, initiative-taking, and customer orientation trainings aim to build a common professional foundation for all employees. Practical frameworks from Japanese business culture, such as the HOURENSOU approach, “Conclusion First” principle, and the importance-urgency matrix, are covered at this level.

Trainer Team: Experience from the Field

Gakken Turkey’s trainer team consists of professionals who possess not only theoretical knowledge but also many years of field experience. The team includes ICF-certified coaches, Kaizen leadership experts with Toyota backgrounds, senior executives from the manufacturing sector, and academics specializing in AI-supported management systems. This strong team ensures that corporate training processes are designed and implemented in a way that creates real impact in the field. Trainings are offered in Turkish, English, and Japanese, and can be delivered in face-to-face, online, and hybrid formats.
