Today, I’m excited to introduce the “Kiwanami (極 – meaning ‘Ultimate’) Writing Mat” by Kyoei Plastic Co., Ltd.
I purchased the “A4+” size, which is slightly larger than a standard A4 sheet.
The price was 1,045 yen (approx. $7.00 USD). While it’s a bit pricey for a writing mat, the quality far exceeded my expectations. I was truly moved by how much it improves the “writing experience” once you actually use it.
Incredible Stability and “Paper-Hugging” Feel
The most remarkable thing is how it feels under your pen.
The pen or pencil seems to cling to the paper, allowing you to control pressure effortlessly while writing with a sense of complete stability.
Because the mat is 2.0mm thick, it has a nice weight that prevents the paper from slipping. Writing feels incredibly smooth, as if the pen is “suctioned” to the paper. This stability helps me focus on every single stroke, making my handwriting look neater and more beautiful than usual.
Reversible Design with Two Different Writing Textures
A great feature of this product is that it is reversible, and each side offers a slightly different writing feel:
| Side | Features | Writing Feel |
| Front (Grid) | Slight resistance | Perfect for sharp, precise characters |
| Back (Plain Black) | Smooth & frictionless | Ideal for fluid, fast-paced writing |
When writing on the Front (Grid) side, there is a subtle “grip” that helps you stay conscious of the character’s shape. On the Back (Black) side, there is almost no resistance, allowing the pen tip to glide across the paper. It’s very convenient to be able to switch based on your needs or mood.
Professional Performance: Great for Signatures and Stamps
This mat isn’t just for daily notes; it shines in professional business settings too.
- Ideal for signing contracts and using hanko (seals).
- Classy enough to offer to important clients.
The moderate cushioning ensures a clear, smudge-free impression and stable pen pressure.
Using such a high-quality tool during important client interactions gives a truly professional impression.
Summary
The “Kiwanami Writing Mat” by Kyoei Plastic is more than just a writing aid; it’s a masterpiece that elevates the act of writing itself.
For just 1,045 yen (approx. $7.00 USD), you can experience this “ultimate” writing comfort.
The A4+ size (306 × 228mm) comfortably covers an A4 document without any edges sticking out.
From daily journaling to important business deals, this is a tool you’ll cherish for a long time.
