Introduction
Welcome to the world of nanoblock! This manual provides detailed instructions for assembling your Kawada Nanoblock Imperial Japanese Navy Battleship Yamato (Model NB-004). Nanoblock is an innovative micro-sized building block system, with each stud measuring a mere 4mm x 4mm. This miniature scale allows for the creation of incredibly detailed and intricate models that are not possible with larger block systems. Designed for enthusiasts aged 12 and above, this set offers a rewarding and immersive building experience.

Safety Information
WARNING: CHOKING HAZARD - Small Parts. This product contains small parts and is not suitable for children under 3 years of age. Keep all blocks and packaging materials away from young children to prevent accidental ingestion or choking. Adult supervision is recommended during assembly, especially for younger builders.
Setup and Preparation
- Unpack Contents: Carefully open the product box and remove all bags of nanoblocks and the instruction booklet.
- Organize Blocks: Due to the large number and small size of the blocks (over 1700 pieces), it is highly recommended to sort them by color and shape before beginning assembly. Using small containers or a sorting tray can greatly assist in this process and prevent loss of pieces.
- Clear Workspace: Ensure you have a clean, well-lit, and stable surface for assembly. The small size of the blocks makes them easy to lose if the workspace is cluttered.
- Review Instructions: Familiarize yourself with the entire instruction booklet before starting. Pay close attention to the visual diagrams and step-by-step sequences.
- Optional Tools: While not strictly necessary, a pair of fine-tipped tweezers can be very helpful for handling the tiny blocks and placing them precisely. A nanoblock specific tool (like NB-019, if available separately) can also aid in separating incorrectly placed blocks.
Assembly Instructions
Follow the step-by-step diagrams provided in the instruction booklet. Each step will show which blocks to add and where to place them.
- Start from the Base: The model typically begins with the base structure, often the hull of the battleship. Build layer by layer, ensuring each block is firmly connected.
- Color Coding: Pay attention to the color of the blocks in the diagrams. Some sections may use specific colors to represent different parts of the ship.
- Orientation: Ensure blocks are placed in the correct orientation as shown in the diagrams. Incorrect orientation can affect the stability and appearance of the final model.
- Pressure: Apply gentle, even pressure when connecting blocks. Avoid excessive force, which could damage the blocks or cause the model to become unstable.
- Detailed Sections: The Battleship Yamato model includes many intricate details such as turrets, superstructure, and deck features. Take your time with these sections to ensure accuracy.

Maintenance
Once assembled, your Nanoblock Battleship Yamato model requires minimal maintenance.
- Cleaning: To remove dust, gently wipe the model with a soft, dry cloth or use a soft brush. Avoid using water or cleaning solutions, as they may damage the blocks or cause discoloration.
- Storage: Store the assembled model in a stable location away from direct sunlight, extreme temperatures, and high humidity to prevent warping or fading of the blocks.
- Handling: Handle the model with care, especially when moving it, to prevent parts from detaching.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Missing blocks | Blocks may be very small and easily overlooked, or accidentally discarded with packaging. | Double-check all packaging materials and your workspace thoroughly. If still missing, contact Kawada customer support. |
| Blocks not connecting securely | Incorrect block orientation or debris on the studs. | Ensure blocks are oriented correctly as per instructions. Check for any foreign particles on the studs and remove them. Apply firm, even pressure. |
| Model is unstable or parts fall off | Blocks not fully pressed together, or incorrect placement in earlier steps. | Review previous steps to ensure all blocks are correctly and firmly attached. Re-press any loose connections. |
| Difficulty separating blocks | Blocks are tightly fitted. | Use a nanoblock separator tool (if available) or a thin, flat object (like a small plastic pry tool) to gently pry them apart. Avoid using excessive force or sharp objects. |
