4. Assembly Instructions
Follow these steps to assemble your Nanoblock Shuri Castle:
- Preparation: Open the package and carefully empty all blocks onto a clean, flat surface. It is recommended to sort the blocks by color and shape to facilitate easier assembly.

- Layer by Layer: Build the model layer by layer, ensuring each layer is stable before proceeding to the next. Refer to the diagrams frequently to confirm correct placement.

Once assembled, your Nanoblock Shuri Castle is ready for display. While it is a robust model, please observe the following:
- Handling: Handle the completed model with care. Avoid dropping it or applying excessive force, as small blocks may detach.
- Display Location: Place the model on a stable, flat surface away from direct sunlight, extreme temperatures, and high humidity to prevent potential discoloration or warping of blocks over time.
- Educational Value: The completed model serves as an excellent educational tool to learn about Japanese architecture and the historical significance of Shuri Castle.
6. Maintenance
To keep your Nanoblock Shuri Castle in optimal condition:
- Cleaning: Dust the model regularly with a soft, dry brush or a can of compressed air. For more stubborn dirt, gently wipe with a slightly damp cloth and then dry immediately. Avoid using harsh chemicals or abrasive cleaners.
- Storage: If disassembling for storage, keep all blocks in a sealed container to prevent loss and protect them from dust.
7. Troubleshooting
If you encounter any issues during assembly or with your completed model, consider the following:
- Missing Pieces: Carefully check all packaging materials and the assembly area. If pieces are genuinely missing, please contact KAWADA customer support with your product details.
- Difficulty Assembling: Re-examine the instruction booklet for the current step. Ensure you are using the correct blocks and placing them in the exact positions indicated. Sometimes, a small misplacement can affect subsequent steps.
