Japanese Cedar Building Blocks (12 pieces) - Safe for Infants from 0 Years Old | Choking Hazard Prevention Design, Carefully Beveled Edges for Safety | Tsumiki-zu Building Blocks

These are building blocks made from domestic cedar, designed for babies from 0 months old, with careful consideration given to size, material, and finish, assuming that babies will put everything in their mouths.

They can be safely chosen as a "first toy" or a "baby gift."

● Do you have these concerns? ●

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

ー Is it too small and dangerous?

ー Will it really help with their intellectual development?

These are building blocks from Tsumikies that address these concerns through their materials, design, and concept.

● Three 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 considers the risk of accidental ingestion.

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

Reason 2 | Unpainted, domestic cedar material

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

・Unpainted, safe even if licked

・You can feel the scent and warmth of the wood

Reason 3 | Can be played with for a long time as they grow

Building blocks are not just for "stacking."

0 months: Gripping, licking, dropping

1 year: Arranging, stacking, knocking down

2 years and up: Shape play, imaginative play

Since the way they are played with changes as the child grows, they are educational toys that can be used for a long time.

● Commitment to safety ●

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

・Size considered to prevent accidental ingestion

・Unpainted, carefully chamfered

・Manufactured and inspected in Japan

*While we take all possible measures for safety, please ensure adult supervision during use.

● Skills nurtured by playing with building blocks ●

Playing with building blocks contains many elements that promote a baby's development.

Manual dexterity, concentration, spatial awareness, imagination

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

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

★ "TSUMIKIES OTEHON" app released in May 2026 ★

The "Tsumikies Otehon" app is a new educational app that faithfully reproduces the "Tsumikies building blocks," educational blocks that cherish the warmth of wood, in the digital world. The three-dimensional blocks, which realistically represent wood grain and colors, give the sensation of looking at real objects.
Furthermore, a major feature of this model app is that each work does not have a name.
Deliberately not assigning names to the works encourages children to expand their imagination without preconceived notions. A work that one child sees as a "house" might be seen as a "rocket" by 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 building block creations in the real world.

The download is free, and 30 out of about 150 works can be viewed for free.
