Japanese Cedar Building Blocks for Ages 0 and Up｜Safe with Anti-Swallowing Design and Careful Chamfering｜Tsumiki-zu Building Blocks (10 Cubes)

These are wooden blocks made from Japanese cedar, designed to be safe for babies who tend to put everything in their mouths. Every detail, including size, material, and finish, has been carefully considered, making them suitable for children from 0 years old.

You can confidently choose them as a "first toy" or a "baby gift."

●Do you have any of these concerns?●

— Is it safe for my baby to put in their mouth?

— Is it too small and dangerous?

— Will it really contribute to their intellectual development?

Tsumikies blocks address these concerns through their material, design, and concept.

●3 Reasons Why Tsumikies Blocks Are Chosen●

Reason 1 | Size designed to prevent accidental ingestion

Babies explore toys by licking them. Tsumikies blocks are designed with a size that considers the risk of accidental ingestion.

・Safe size, not too small, with sides of 4cm or more
・Gentle shape with carefully rounded corners and chamfered edges

Reason 2 | Unpainted, Japanese cedar material

Only domestic Japanese cedar wood is used. No paint is applied, preserving the natural texture of the wood.

・Safe even when licked, as it is unpainted

・Allows you to feel the scent and warmth of the wood

Reason 3 | Can be played with for a long time, adapting to growth

"Stacking" is not the only way to play with blocks.

0 years old: Grasping, licking, dropping

1 year old: Arranging, stacking, knocking down

2 years and older: Shape play, pretend play

As the way of playing changes with growth, it is an educational toy that can be used for a long time.

●Commitment to Safety●

Because they are toys for babies, we prioritize "safety" above all else.

・Size designed to prevent accidental ingestion

・Unpainted, carefully chamfered

・Manufactured and inspected in Japan

※While we take every precaution for safety, please ensure adult supervision during use.

●Skills Developed Through Block Play●

Block play contains many elements that promote a baby's development.

Sense of touch in fingers, concentration, spatial awareness, imagination

Tsumikies blocks are educational blocks that nurture children's non-cognitive abilities through "shape matching" and "sprout marks."

We value "learning through play" rather than the idea of "having to educate."

★ "Tsumikies Otehon" App to be released in May 2026 ★

The "Tsumikies Otehon" app is a new educational app that faithfully reproduces the educational wooden blocks "Tsumikies blocks" in the digital world, cherishing the warmth of wood. The three-dimensional blocks, with their wood grain and colors realistically expressed, give a sense of looking at the real thing.
Furthermore, a major feature of this model app is that each work has no specific name.
By deliberately not defining a work name, children are encouraged to expand their imagination without fixed ideas. A work that looks like a "house" to one child might look like a "rocket" to another, and neither is wrong.
We hope that by adding their own uniqueness to the works observed in this app, children will create even more wonderful original block creations in the real world.

Downloading is free, and 30 out of approximately 150 works can be viewed for free.
