The first theme is “SF Mecha”.
Cool things and cute things.
Beginners, children and those who have been making models for a long time are all welcome to participate!
We’re looking forward to your creative works!

Theme 1

“SF Mecha”

What are “Scratch Building” and “Mixing Build”?

“Scratch Building” means making models from scratch by using various materials instead of just assembling parts of an existing plastic model kits. Please use materials such as plastic boards and wood, remake familiar materials and create works from your favorite materials.

“Mixing Build” means to re-use and process parts from different model products to create one model. Therefore, you can use other models such as plastic models.
For these contests, we are collecting models themed on your own “SF Mecha” made based on your ideas.
