With materials and a playful spirit, we light up everyday life with creativity
Tokyo-Kanto

Area
A Town of Crafts Where Tradition and Innovation Intersect
Located in northeast Tokyo, Taito Ward is an area where traces of Edo culture remain, home to sites like Sensoji Temple and Ueno Park.
Distinctive neighborhoods such as Asakusa, Ueno, and Kuramae have long thrived with commerce and skilled craftsmanship, developing into production hubs for diverse crafts and household goods including decorative metal fittings, leather goods, printing, toys, accessories, and stationery.
Craftspeople who value meticulous handiwork gathered here, and after the war, a wholesale district formed.
The concentration of materials and tools cultivated fertile ground for creativity.
In recent years, centered around Kuramae and Asakusabashi, craft brands and designers have established studios, leading to a growing movement that blends traditional techniques with contemporary design. Materials like leather, metal, and paper are transformed into products by small workshops.
These crafts, meticulously crafted with attention to texture and detail beyond mere durability and functionality, are gaining attention both domestically and internationally as items that enhance daily life.
urthermore, Ueno boasts a cluster of art museums, museums, and music halls, where artistic and academic stimulation provides fresh perspectives for craftsmanship.
Taito Ward stands as the intersection of Japanese craft and urban culture—a place where items born from respect for materials, meticulous attention to detail, and the quiet power to enrich daily life are created.

History
Breathing new life into plastic
Based in Taito Ward, Tokyo, Kobayashi Co., Ltd. has supported Japanese daily life through plastic products like packaging materials and containers since its founding.
Inheriting the spirit of Kuramae, a town known for manufacturing, the company focuses on developing new materials and proposing environmentally conscious products while adapting to changing times.
Based on years of experience and expertise,"tontamu" was born as a brand that offers a little help so you can enjoy life to the fullest.
The brand name reflects our desire for people to fully enjoy the potential of the materials.
We aim to create items that add color to everyday life and bring a sense of "a sense of creative freedom" into daily moments.
Its inaugural collection features the biomass material kit "HEAD PET" and "SAKU IKA," born from Waste materials.
Since its debut, the brand has garnered attention in craft and lifestyle circles as one that encourages re-examining materials and proposes the joy of hands-on creation.

Characteristic
The Trio of Materials, Experience, and Playfulness
At the core of tontamu lies the trinity of "materials, experience, and playfulness."
The primary material is "ReseamST®," an environmentally conscious plastic blended with corn starch.
Compared to conventional plastics, it offers a softer, matte texture and flexible workability, enabling experiences like tearing, drawing, and folding—allowing users to touch it with their hands and enjoy its transformation.
The signature product, "HEAD PET," is a craft kit that allows users to freely shape animals and imaginary creatures, maximizing the material's expressive potential.
By creating and wearing your own unique character, it unites play and creativity. Additionally, "SAKU IKA" repurposes trays destined for disposal, transforming the joy of hand movement into a new form through the clever concept of a "tearable squid."
Tontamu products are experiential items that value "touching with your hands and experiencing change," much like traditional crafts.
They weave creativity and discovery into daily life.
By combining the reliable quality unique to Japanese manufacturing with an accessible price point, tontamu brings free thinking and enjoyable playtime into everyday living.

For Customers
Bring the joy of creation into everyday life
We don't view materials merely as "items to be used."
Instead, we cherish the "potential felt through touch" and the "ideas born from movement."
In an era where convenience takes precedence, we want to offer the experience gained by deliberately using your hands.
It was with this desire that tontamu was born.
We hope both adults and children will touch the materials, change their form, and expand their world of play.
Life has its ups and downs, so you might as well enjoy both!
We invite you to enjoy many moments of fun in your daily life with tontamu.
We will continue to be a presence that adds small discoveries and comfort to your life.
