The Perfect “First Toy”
This set of blocks is crafted entirely from solid Japanese wood and thoughtfully designed for babies. Easy for little hands to grasp from around 6 months of age, each piece features a silky-smooth finish that feels gentle and reassuring. It is an ideal first toy to accompany your baby’s earliest discoveries.
Safe to Put in the Mouth
Beautifully Smooth Finish
Around 6 months of age, babies begin exploring the world by holding objects and putting them in their mouths. The finely polished wooden surface gently stimulates visual, tactile, and oral senses, supporting healthy brain development. Finished with a baby-safe natural oil, these blocks are safe and comforting even when mouthed.
Learning Through Different Types of Wood
This block set uses several kinds of Japanese hardwoods, including cherry, maple, and chestnut. Each type of wood has its own natural color, weight, and texture. As babies play, they naturally notice these differences through touch and movement. It is a toy that allows children to learn directly from real wood—an experience that single-material plastic toys cannot offer.

Comfortable for Small Hands
Rounded, Gentle Edges
Every block is carefully polished by skilled craftspeople, with all corners softly rounded and the surface smoothed to a gentle sheen. The pleasant texture invites babies to grasp and hold the blocks again and again. With a mix of round and square shapes, babies gradually begin to recognize differences in form as they touch and mouth each piece.

Play That Grows with Your Baby
As soon as babies can sit, they enjoy holding the blocks, mouthing them, and tapping them together. When they begin to crawl, rolling the blocks becomes a new source of fun. As they pull themselves up to stand, knocking down stacks built by themselves or an adult brings great delight. Around one year of age, the blocks fit perfectly in small hands. Simple interactions like passing blocks back and forth while saying “Here you go” and “Thank you” also encourage early language. At every stage, this toy naturally supports your child’s language, movement, and imagination.
Beautiful Down to the Box
Perfect for Gifting
The wooden storage box is carefully crafted from hardwoods such as horse chestnut and birch. Decorative accents made from zelkova and cherry highlight the natural colors of the wood, without dyes or paint. Many customers remark that it is “even more beautiful in person,” making it a popular choice for special gifts.
Made to Be Enjoyed for Many Years
Please store the blocks in a dry place to prevent mold. If the surface ever feels rough, rubbing firmly with a cotton cloth will help restore smoothness. You may also apply baby-safe natural oil to revive the wood’s luster. With proper care, these blocks can be cherished for many years and passed down to siblings or even grandchildren.
Quality Trusted by the Imperial Household
This product has been introduced in reference books as a toy once used by Her Imperial Highness Princess Aiko. Photographs published in Imperial Household materials show it being lovingly used, which has deeply touched many customers. It is said that when the National Sports Festival was held in Kochi Prefecture, Her Majesty the Empress selected this set as a gift for Princess Aiko.
Carefully Finished
One by One, by Hand
A great deal of time is devoted to the polishing process. This patient, repetitive work continues for many hours to achieve the smoothness we value. Because of this careful craftsmanship, we may not always be able to ship immediately after an order is placed. Each block is made with the hope that it will become a baby’s cherished companion. We appreciate your understanding.
