The Culture of Writing and Japanese Notebooks Explained Through Data

Japanese stationery is known around the world for its exceptional quality and thoughtful design.
In particular, Japanese notebooks are beloved by stationery enthusiasts for their paper quality, writing comfort, and the cultural tradition of writing that surrounds them.

Even in the digital age, writing by hand remains an important part of everyday life in Japan.
A notebook is not just a tool for recording information. It is also a space to organize thoughts, reflect on feelings, and create moments of quiet focus.

Japanese stationery has long been designed with more than practicality in mind.
Great care is given to how an object feels in the hand, how smoothly a pen moves across the paper, and how the object fits naturally into daily life.

Behind this approach lies a long tradition of craftsmanship, materials, and a deep cultural appreciation for writing.

 

A ¥400 Billion Market Supported by the Culture of Writing

The Japanese stationery and office supplies market reached approximately ¥388.5 billion (about $2.6 billion USD) in manufacturer shipments in 2024.

Even as digitalization and paperless workflows continue to grow, this market remains remarkably resilient.
The reason lies in Japan’s deeply rooted culture of writing.

Today, stationery is increasingly shifting from a purely functional necessity to something closer to a personal and expressive object.
Many people use notebooks not only for work or study, but also for hobbies, creativity, and self-expression.

Japanese Stationery Brands Expanding Around the World

The global popularity of Japanese stationery is also reflected in the international sales of major manufacturers.

For example, Pilot Corporation generates about 65% of its revenue overseas, while Mitsubishi Pencil earns more than half of its sales internationally.
These numbers clearly show how widely Japanese writing tools have spread across the world.

Individual products have also achieved remarkable success.

Pilot’s Frixion erasable pen series surpassed 1 billion units sold within just eight years of its launch.
In fact, nearly 70% of ballpoint pens produced in Japan are exported overseas.

Through decades of innovation focused on writing comfort and functionality, Japanese stationery has effectively become a global standard.

The Rise of Journaling: Scientific Evidence Behind Writing

In recent years, journaling—the practice of organizing thoughts and emotions through writing—has gained popularity worldwide.

Interestingly, about 60% of people who practice journaling belong to Generation Z (according to research by Feppiness Inc.).
This suggests that even digital-native generations are rediscovering the value of handwriting.

Scientific studies also support the benefits of writing.

Research on expressive writing shows that writing for just 20 minutes a day for three to four consecutive days can significantly improve mood.

Another experiment conducted in 2018 found that participants who wrote a to-do list before going to bed fell asleep about nine minutes faster than those who wrote about past events.

Among people who practice journaling regularly, the top reasons include:

• Mental stability (40.9%)

• Helping achieve goals (40.0%)

• Organizing thoughts (39.1%)

These findings suggest that writing is not only a creative activity, but also a powerful tool for mental clarity.

The Writing Experience Rooted in Japan’s Paper Culture

One of the reasons Japanese notebooks are so highly regarded is the attention to writing comfort.

The smooth compatibility with fountain pens and gel pens, the way a notebook opens flat, and paper that resists ink bleed-through—these qualities reflect generations of expertise in papermaking.

Traditional Japanese paper, known as washi, is made from plant fibers such as kozo (mulberry).
Its unique texture and durability have influenced Japanese paper culture for centuries, and elements of this heritage continue to shape modern notebook design.

Kanazawa: A City That Cultivated a Culture of Beauty

KASHIKO was born in Kanazawa, a city with a remarkable cultural history.

In 1583, Maeda Toshiie, the founding lord of the Kaga domain, entered Kanazawa Castle and established the foundations of the city.
The region later developed into one of the wealthiest domains in Japan, controlling territories equivalent to modern-day Ishikawa, Toyama, and parts of Fukui, with an output exceeding one million koku of rice. This era became known as Kaga Hyakumangoku.

Under the patronage of the Maeda family, arts and culture flourished.

Tea ceremony, Noh theater, Kaga Yuzen silk dyeing, gold leaf craftsmanship, and Kutani porcelain all developed during this period.
Many of the traditional crafts that still define Ishikawa today were nurtured during these centuries.

The sensibility that even everyday tools should possess beauty grew out of this cultural environment.

KASHIKO notebooks quietly carry forward the memory of this place.

The Quiet Value of Writing by Hand

In an age dominated by smartphones and computers, writing by hand has become something rare—and perhaps more meaningful than ever.

The simple act of putting pen to paper helps organize thoughts and creates space for reflection.
Psychology increasingly confirms that writing can improve focus, clarity, and emotional balance.

KASHIKO is a notebook brand born in Kanazawa, where craftsmanship continues to thrive.

Whether seen through data or experienced through the senses, the value of writing feels especially significant in the digital age.

If a KASHIKO notebook can accompany even a small moment of quiet reflection in your daily life, we would be honored.

Each KASHIKO notebook is carefully finished by hand in a workshop in Kanazawa.
