Kuroki Seisakusho Co., Ltd. is a Japan-based design and manufacturing company specializing in custom miniature diorama accessories, acrylic products, original goods, and hands-on creative workshops.
We create small-scale products that bring stories, brands, and memories to life. Our work includes miniature figures, trees, lighting kits, acrylic keychains, display parts, railway-themed goods, and event-specific items for museums, railway companies, commercial facilities, corporate clients, and hobby enthusiasts.
Using in-house equipment such as UV printers, laser cutters, and 3D printers, we are able to handle small-lot production, custom designs, prototypes, and event-specific products with flexibility and speed.
We provide a wide range of design and manufacturing services, including:
Custom miniature figures and diorama accessories
Acrylic keychains, stands, and display items
Railway-themed original goods
Lighting kits for model railways and dioramas
Small-lot production for events and museums
OEM goods and custom-made promotional items
Hands-on workshops for children and families
In addition to manufacturing, we also plan and operate interactive workshops where children and families can create their own original keychains and diorama-style items.
Our workshops are designed to be easy to understand, fun to participate in, and suitable for a wide range of visitors. They are especially popular at railway museums, commercial facilities, family-oriented events, and promotional campaigns.
We can customize the workshop theme, design, and materials to match the client’s brand, event concept, location, and target audience.
One of our strengths is flexible small-lot production. We can support original projects from planning and design to production and delivery.
Because we use in-house equipment, we can respond quickly to custom requests, limited-edition items, seasonal designs, and event-specific goods.
We are especially experienced in creating products related to railways, vehicles, local tourism, museums, and hobby culture.
Our strength lies in combining Japanese craftsmanship, playful design, and practical event operation.
We do not simply manufacture products. We create items and experiences that help people remember a place, an event, a brand, or a special moment.
From small acrylic goods to hands-on workshops, we aim to create memorable products and experiences through detailed design and careful production.
We are open to international collaborations, custom production, workshop projects, and event-related goods.
We can work with clients who are looking for:
Japan-made original goods
Custom miniature or diorama products
Workshop kits for events
Small-lot promotional items
Railway, museum, tourism, or cultural-themed products
