Soccer Notebook Culture in Asia vs. Europe — The Critical Difference Between 'Writing to Reflect' and 'Watching to Reflect'

When the Footnote Editorial team surveyed soccer education practices worldwide, a clear regional divide in approaches to reflection emerged. This is not merely a difference in habits — it is a systematic difference rooted in educational culture and social structure.

The Japanese Model: Player-Driven 'Writing Reflection'

• Individual players record in soccer notebooks (starting from elementary school age)
• Introspective, subjective entries are the norm (verbalizing emotions and decisions)
• Multiple commercial soccer notebook products exist (e.g., the Shunsuke Nakamura model, Keisuke Honda's 'Dream Notebook')
• The practice has a direct continuity with diary-writing and self-reflection traditions in the school system

The European Model: Coach-Driven 'Watching Reflection'

• Sessions where coaches show players edited video clips
• Objective, tactical analysis is the focus (positioning and data)
• One-on-one meetings and team briefings serve as the settings for reflection
• Individual notebook habits among players are not common practice

In the Japanese school system, 'hansei' (self-reflection) is built into education from early childhood. End-of-day classroom reflection sessions, summer break diaries, and end-of-term self-evaluations — these practices instill the habit of 'verbalizing and reflecting on one's actions' from a young age. The soccer notebook is a natural extension of this educational tradition into sports.

The reason Shunsuke Nakamura — one of Japan's most celebrated midfielders — naturally embraced soccer notebooks in his second year of high school is that the act of 'writing to reflect' was already second nature through years of schooling. For players in the West, 'writing in a notebook after a match' may feel unusual, but for Japanese players it is simply an extension of what they have always done in the classroom.

This cultural background carries important implications when applying findings from Toering et al. (2009), a Dutch study on self-regulation in youth soccer. Their finding that reflection skills correlate with performance suggests that Japan — with its deep educational tradition of reflection — may be uniquely positioned to leverage this advantage even more effectively than in Europe.

Strengths of Video Analysis

• Objectivity — Video eliminates memory bias. A player may believe they released the pass on time, but the footage reveals the delay
• Visual comprehension — For understanding tactics, video can be more efficient than verbal explanation
• Whole-team perspective — Video reveals team-wide movement and off-the-ball runs that individual players cannot see during a match

Limitations of Video Analysis

• Passive — Players are 'shown' the video; the process of actively constructing their own reflection is weak
• Invisible inner reasoning — Video shows 'what happened' but not 'why the player chose that action'
• Weak mental-health coverage — Psychological elements such as anxiety, pressure, and motivation cannot be addressed through video analysis alone

Research by MacIntyre et al. (2014) noted that metacognition in sport has been 'surprisingly under-researched.' While video analysis excels at analyzing 'behavior,' developing 'thinking about thinking (metacognition)' requires active reflection accompanied by verbalization — in other words, the act of writing in a notebook.

A study by Kawasaki et al. (2019) published in Brain Sciences demonstrated that a group tasked with verbally describing their own movements showed significantly greater motor skill acquisition than the control group. Verbalization triggers brain activity that overlaps with motor execution and motor imagery — a mechanism that accelerates skill learning.

Meanwhile, the effectiveness of video analysis has been demonstrated primarily in 'error detection' and 'tactical understanding.' However, research by Cropley et al. (2007) showed that reflective practice interventions improved self-awareness, evaluative skills, and self-efficacy — effects that cannot be achieved through video viewing alone.

Footnote's Original Framework: The Integrated Model

Synthesizing the existing body of research, we believe maximum reflection effectiveness emerges through the following sequence:

1. Immediate verbalization (write) — Verbalize decisions, emotions, and physical sensations right after the match. Record your subjective experience while memory is fresh
2. Objective verification via video (watch) — Compare your written recollections against the footage to discover gaps between perception and reality
3. Gap analysis and goal updating (write) — Analyze the causes of those gaps and record your next action steps
4. Feedback from AI or a coach (receive) — Get an external perspective on trends spanning multiple matches

This four-step model integrates the Japanese 'writing culture' with the European 'watching culture' and adds the modern element of AI-powered feedback. Footnote is designed to facilitate steps 1, 3, and 4 within the app.

South America — Improvisation and Oral Culture

Soccer culture in South America — in countries like Brazil and Argentina — is built on the improvisational foundation of street football. Reflection happens less through structured notebooks or video sessions and more through oral discussion with teammates and coaches. Real-time feedback like 'you could've done more with that play' is a constant part of everyday training.

North America — A Data-Driven Approach

With the rise of MLS, a data-analytics-driven approach has taken hold in the United States. Reflection built on objective data — GPS tracking, distance covered, sprint counts — aligns naturally with America's broader business analytics culture. However, the subjective introspection element tends to be as weak as in the European model.

South Korea — Similarities with Japan and Its Own Identity

South Korea also has an educational tradition of self-reflection, and player recording habits share similarities with Japan. However, influenced by the more regimented discipline culture in Korean soccer, notebooks can sometimes take on the character of 'reports to the coaching staff' — a dynamic that differs from intrinsically motivated self-reflection.

Each regional approach analyzed in this article has its own strengths and limitations. The Footnote Editorial team's proposal is an integrated model that draws on the best of each:

• From the Japanese model — The habit of players verbalizing their own experience. Recording mental and emotional states. Continuity driven by intrinsic motivation
• From the European model — Improving reflection accuracy through objective data. Tactical-level analytical frameworks
• What technology adds — Trend detection across multiple matches (AI analysis). Quantification and visualization of skills. Automated feedback

The importance of this integrated approach is further supported by the latest research from Esposito et al. (2025), published in Scientific Reports. Their finding that a facilitation program based on metacognitive self-questioning significantly improved self-regulation skills in sports coaches reinforces the scientific validity of 'writing reflection.'
