Japanese cypress building blocks safe for babies 0+, designed to prevent choking, with carefully beveled edges for safety｜TSUMIKI-ZU blocks (10 cuboid pieces)

These are building blocks made from domestic Japanese cypress, suitable for infants from 0 years old, with careful consideration given to size, material, and finish, assuming that babies will put everything in their mouths.

They are a safe choice for "first toys" and "baby shower gifts."

● Do you have these concerns? ●

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

- Is it too small and dangerous?

- Will it really lead to intellectual development?

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

● 3 reasons why Tsumikies building blocks are chosen ●

Reason 1: Size designed to prevent accidental ingestion

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

・A safe size of 4 cm or more per side, not too small
・Gentle shape with carefully rounded edges

Reason 2: Unpainted, domestic Japanese cypress material

Only domestic Japanese cypress wood is used. No paint is applied, valuing the natural texture of the wood.

・Safe to lick as it's unpainted

・Enjoy the scent and warmth of wood

Reason 3: Long-lasting play that adapts to growth

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

0 years old: Grasping, licking, dropping

1 year old: Arranging, stacking, knocking down

2 years and older: Shape play, imaginative play

As play changes with growth, these are educational toys that can be used for a long time.

● Commitment to safety ●

Because these are toys for babies, "safety" is our top priority.

・Size designed to prevent accidental ingestion

・Unpainted, carefully rounded edges

・Manufactured and inspected in Japan

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

● Skills nurtured by building block play ●

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

Finger sensation, concentration, spatial awareness, imagination

Tsumikies building blocks are educational building blocks that foster children's non-cognitive abilities through "shape matching" and "leaf marks."

Rather than thinking "I have to educate them," we value "learning through play."

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

"Tsumikies Otehon" app is a new educational app that faithfully reproduces "Tsumikies building blocks," educational blocks that cherish the warmth of wood, in the digital world. The three-dimensional blocks, realistically expressing wood grain and colors, give the sensation of looking at real objects.
Furthermore, a major feature of this example app is that each work has no name.
Deliberately not assigning a name to the work encourages imagination without fixed ideas. A work that one child sees as a "house" may be seen as a "rocket" by another child, and neither is wrong.
We hope you will add your own originality to the works observed in this app and create even more wonderful original building block works in the real world.

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