When we think of reducing plastic waste, stationery might not be the first thing that comes to mind. But pens, clips, erasers, and notebooks—used daily by students, professionals, and creators alike—add up quickly. Thankfully, a new wave of eco friendly stationery is proving that thoughtful design can also be sustainable.
In Japan, where craftsmanship and attention to detail are highly valued, stationery brands are leading the way in creating beautiful, functional items made from recycled materials, including ocean-bound plastics. This blog explores how these products are made, why they matter, and which brands are helping us write a greener future.
Eco friendly stationery refers to writing tools and paper products designed to reduce environmental impact. This can include:
In Japan, many stationery makers are going a step further—transforming waste from the ocean, coasts, or the beverage industry into creative and practical tools.
Each year, millions of tons of plastic enter our oceans, harming marine life and polluting ecosystems. Ocean-bound plastic refers to waste that is discarded near coastlines or rivers and is highly likely to end up in the sea.
Several Japanese stationery companies are addressing this issue head-on by incorporating recovered ocean plastic or fishing nets into their product designs. These efforts not only prevent pollution but give plastic a second life in the form of everyday tools we can use and appreciate.
Here are some standout examples of Japanese stationery that combine design excellence with sustainable innovation:
This sleek, turquoise pen is made from 74.1% recycled materials, including 2% ocean plastic collected from waterways, lakes, and beaches. Pilot released this model in 2020 as part of their broader mission to design pens with lower environmental impact.
This pen proves that sustainability can still feel stylish and refined.
Known for its ultra-smooth writing and fast-drying ink, the Jetstream series by Mitsubishi Pencil is a go-to favorite for students and professionals alike. In 2023, Uni took this bestselling pen in a greener direction with the release of the Jetstream Ocean Plastic model—a bold step toward reducing marine waste.
The body of this pen is made from recycled plastic recovered from coastal areas and waterways, developed through a partnership with The Ocean Plastic Recovery Project, an initiative led by TerraCycle Japan. The project focuses on intercepting plastic waste before it reaches the ocean and turning it into functional, long-lasting tools.
Key features include:
This pen is also included in ZenPop’s Marine Dream Stationery Box, offering an inspiring example of how everyday tools can make a difference—one line at a time.
This minimalist pouch is made from ocean-bound plastic waste, collected within 50 km of coastlines—an area where discarded plastics are highly likely to end up in the sea.
Developed in collaboration with the Surfrider Foundation Japan, it’s a compact, functional case designed with sustainability at its core.
Look for the plastic bottle icon on each item—this shows how many recycled 500ml PET bottles were used in its production, offering a clear and tangible way to understand your environmental impact.
A clever pen case that transforms into a standing pen holder—now made using recycled fishing nets, one of the most dangerous forms of marine waste. It’s a great example of turning environmental harm into helpful design.
At first glance, the NeoCritz looks like a sleek zippered pouch—but unzip it, fold down the top, and it transforms into a standing pen holder that brings vertical convenience to your desk.
In this special edition, Kokuyo goes a step further by using recycled fishing nets as the primary material—an innovative step toward reducing one of the ocean’s most harmful types of plastic waste. Abandoned or lost fishing nets, also known as “ghost nets,” are notorious for entangling marine animals and damaging ecosystems. By reclaiming and repurposing them, Kokuyo gives these nets a new life as something both beautiful and functional.
This NeoCritz model still offers the same smart features:
Each pen case includes a unique hangtag detailing the story of how it was made from marine debris, inviting users to reflect on the connection between daily tools and ocean conservation.
Not every innovation focuses on ocean plastic—some products use plant-based, biodegradable, or recycled materials from daily life. Here are a few worth discovering:
Made using biomass materials, including scallop shells, released in April 2024.
A file folder made from recycled tea leaves using ITO EN’s "Used Tea Leaves Recycling System."

Choosing eco friendly stationery isn’t just about replacing plastic—it’s about rethinking how we interact with everyday tools. Each refillable pen or paperless memo pad is a step toward a more mindful, sustainable lifestyle.
Whether you're journaling, planning your day, or preparing for exams, these tools allow you to express yourself while caring for the planet.
If you’re curious to try some of these innovative items, ZenPop’s latest Marine Dream Stationery Box features the ocean-friendly uni Jetstream ocean plastic pen. It’s a gentle introduction to sustainable writing tools—and a beautiful way to bring the calm of the ocean to your desk.
Eco friendly stationery is more than a niche trend—it’s a growing shift in how we design and consume everyday items. In Japan, where craftsmanship and respect for materials are deeply embedded in the culture, stationery brands are leading by example.
For instance, Greem-net is Uni’s eco-focused product line, featuring items that meet Japan’s Green Purchasing Law by using at least 40% recycled plastic, and also carry the Eco Mark certification, which requires 70% or more recycled content by weight.
By choosing tools made from recycled or renewable materials, you're not just writing notes—you're helping write a better future.
