Japanese cypress blocks for ages 0 and up | Anti-choking design and carefully beveled for safety | Tsumiki-zu Blocks (10 triangular prism pieces)
These are building blocks made from Japanese cypress, designed for babies who put everything in their mouths. Every detail, from size and material to finish, has been carefully considered, making them suitable for babies from 0 years old.
They are a safe choice for a "first toy" or as a "baby shower gift."
● Do you have these concerns? ●
—Is it safe for my baby to put in their mouth?
—Is it too small and dangerous?
—Does 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 considers the risk of accidental ingestion.
・Safe size, not too small, with sides 4cm or more
・Gentle shape with carefully chamfered and 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 because it's unpainted
・Allows you to feel the scent and warmth of wood
Reason 3|Can be enjoyed for a long time as your child grows
Stacking is not the only way to play with building blocks.
0 years old: Grasp, lick, drop
1 year old: Arrange, stack, knock over
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 ●
Since these are toys for babies, "safety" is our top priority.
・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.
Finger sensation, concentration, spatial awareness, imagination
Tsumikies building blocks are educational blocks that foster children's non-cognitive abilities through "shape matching" and "leaf marks."

Instead of thinking "I have to educate them," we value "learning through play."
★May 2026 "Tsumikies Otehon" app to be released★

"Tsumikies Otehon" app is a new educational app that faithfully reproduces the "Tsumikies building blocks," an educational toy that values the warmth of wood, in the digital world. The three-dimensional blocks, realistically representing wood grain and colors, give the sensation of looking at real objects.
Furthermore, a major feature of this example app is that each work does not have a name.
Deliberately not naming the works allows for expanding imagination without being bound by preconceived notions. A work that one child sees as a "house" may be seen as a "rocket" by another child, and neither is wrong.
We hope that you will add your own originality to the works observed in this app and 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.
