Major Japanese nursery operator 'Kodomo no Mori Holdings' (670 nurseries nationwide) will roll out a free ancient coin-themed picture book and sensory material library 'Nukumori Coin Ehon Library' across its affiliated nurseries. The 12-volume series designed for ages 0-6 includes sensory boards with silicone replica coins. Free distribution to 1,000 non-affiliated nurseries and children's centers by end of 2026 has also been confirmed, attracting attention as an initiative to plant ancient coin culture through tactile early childhood education.
