- Sofubi is a type of vinyl — specifically, soft vinyl with more plasticizer for a flexible, rubbery feel. All sofubi is vinyl, but not all vinyl is sofubi.
- Both sofubi and regular PVC vinyl figures are made using the same rotocasting process. The difference is in the material composition, not the manufacturing method.
- Sofubi figures are hollow, lightweight, and have a handmade aesthetic with visible seam lines. PVC figures are harder, more durable, and have sharper details.
- Production costs are similar for both materials. Sofubi tends to be more expensive at retail because it's often produced in smaller, limited-edition runs.
- Choose sofubi for organic, hand-crafted aesthetics and Japanese designer toy appeal. Choose PVC for sharp detail, durability, and high-volume production.
What Is the Difference Between Sofubi and PVC?
Sofubi and PVC are both vinyl materials — but they're not the same thing. Sofubi (ソフビ, from the Japanese "soft vinyl") is a specific type of vinyl compound with a higher plasticizer content, making it softer and more flexible. PVC (polyvinyl chloride) is the broader material category that includes everything from rigid pipes to soft vinyl toys.
When collectors talk about "sofubi vs PVC," they're really comparing two ends of the vinyl spectrum: soft, flexible vinyl (sofubi) versus harder, more rigid vinyl (regular PVC). Both are made using the same rotocasting process, but the material feels and behaves differently.
Here's the quick version: if you squeeze a sofubi figure, it gives. If you squeeze a regular PVC figure, it doesn't. That's the plasticizer at work.
What Does Sofubi Mean?
Sofubi (ソフビ) literally means "soft vinyl" in Japanese. The term emerged in the 1960s when Japanese toy companies started producing hollow vinyl kaiju (monster) toys — think Godzilla, Ultraman, and other tokusatsu characters. These toys had a distinctive soft, rubbery feel compared to the hard plastic toys of the era.
Today, sofubi is closely associated with Japanese designer toy culture. Brands like Bullmark, Marusan, and modern indie artists produce sofubi figures that celebrate the handmade, slightly imperfect aesthetic of the original kaiju toys. The seam lines, slight color variations between pieces, and tactile softness are features, not bugs.
If you're familiar with the vinyl figure world, sofubi represents one end of the spectrum — the handcrafted, limited-edition, art toy end.
Sofubi vs PVC: Material Properties Compared
| Property | Sofubi (Soft Vinyl) | Regular PVC (Hard Vinyl) |
|---|---|---|
| Hardness (Shore A) | 50–70 | 70–85 |
| Flexibility | High — squeezes easily | Low — firm, rigid feel |
| Weight | Light (hollow) | Light (hollow) |
| Detail level | Good (soft edges) | Better (sharper edges) |
| Seam lines | Visible (part of aesthetic) | Minimized (trimmed close) |
| Durability | Good (flexible, won't crack) | Very good (rigid, impact-resistant) |
| Aesthetic | Handmade, organic, retro | Clean, precise, modern |
| Manufacturing process | Rotocasting | Rotocasting |
The key difference is plasticizer content. Sofubi compounds contain 30–50% plasticizer by weight, which gives them that characteristic soft, squeezable feel. Regular PVC compounds contain 10–25% plasticizer, making them firmer and more rigid.
How Is Sofubi Manufactured?
The sofubi manufacturing process is identical to regular vinyl rotocasting — the only difference is the material. Liquid soft vinyl compound (with high plasticizer content) is poured into a hollow metal mold. The mold is heated and rotated on multiple axes, coating the interior walls. After cooling, the hollow shell is removed, trimmed, and hand-painted.
Because sofubi is softer, it tends to release from the mold more easily than harder PVC. This means less trimming and fewer defects. On the flip side, the soft material is more prone to warping if the mold temperature isn't controlled precisely.
Most sofubi production happens in Japan and a handful of factories in China that specialize in Japanese-style vinyl toys. The process is slower and more hands-on than injection molding — which is why sofubi figures are often produced in smaller batches (200–500 pieces) rather than thousands.
Which Is Better for Collectible Figures?
There's no universal "better" — it depends on what you're making and who you're making it for.
Choose sofubi if:
- Your design has organic, rounded shapes (monsters, characters with soft features)
- You're targeting the Japanese designer toy market or collectors who value handmade aesthetics
- You want a tactile, squeezable feel that stands out from hard plastic figures
- You're producing limited editions (200–500 pieces) and don't need razor-sharp detail
- You like the retro, hand-crafted look with visible seam lines as part of the charm
Choose regular PVC if:
- Your design has sharp details, fine textures, or small parts
- You need a rigid, durable figure for retail distribution
- You're producing at higher volumes (1,000+ pieces)
- You want a clean, modern aesthetic with minimal seam lines
- You're making action figures or articulated toys that need structural rigidity
Are Sofubi Figures More Expensive?
Production costs are similar. The material cost difference between sofubi compound and regular PVC compound is small — maybe 10–15% more for sofubi. The real price difference comes from market positioning: sofubi figures are often produced in smaller quantities (limited editions of 200–500 pieces) and marketed as premium collectibles, so the retail price is higher.
A sofubi figure produced in a run of 300 pieces might retail for USD 40–80. A comparable PVC figure produced in a run of 2,000 pieces might retail for USD 15–30. The production cost per unit is similar — the retail price reflects scarcity and market positioning, not manufacturing cost.

Frequently Asked Questions
What is the difference between sofubi and PVC?
Sofubi (soft vinyl) and PVC are both vinyl materials, but sofubi has more plasticizer, making it softer and more flexible. Sofubi figures are hollow, lightweight, and have a rubbery feel with visible seam lines. PVC figures are harder, more durable, and have sharper details. Both are made using rotocasting, but the material composition differs.
What does sofubi mean?
Sofubi (ソフビ) is a Japanese term that literally means 'soft vinyl.' It refers to hollow vinyl toys made using the rotocasting process. The term originated in Japan in the 1960s to describe soft vinyl kaiju (monster) toys. Today, sofubi is associated with Japanese designer toy culture and handmade collectible figures.
Is sofubi the same as vinyl?
Sofubi is a type of vinyl — specifically, soft vinyl. All sofubi is vinyl, but not all vinyl is sofubi. Regular vinyl toys can range from semi-rigid to hard depending on the plasticizer content. Sofubi is always soft and flexible, with a Shore A hardness typically between 50 and 70.
How is sofubi manufactured?
Sofubi is manufactured using the rotocasting process. Liquid soft vinyl compound is poured into a hollow metal mold, which is heated and rotated on multiple axes. The material coats the interior walls, forming a hollow shell. After cooling, the figure is removed, trimmed, and hand-painted. The process is the same as regular vinyl, but the material has more plasticizer for a softer feel.
Which is better for collectible figures: sofubi or PVC?
It depends on your design goals. Sofubi is better for organic, hand-crafted aesthetics with a tactile, rubbery feel. PVC is better for sharp details, durability, and mass production. If you're targeting the Japanese designer toy market or collectors who value handmade quality, choose sofubi. If you need precise detail and high volume, choose PVC.
Are sofubi figures more expensive than PVC?
Sofubi and PVC figures have similar production costs since they use the same rotocasting process. The material cost difference is minimal. Sofubi figures tend to be more expensive at retail because they're often produced in smaller quantities (limited editions) and marketed as premium collectibles. The production cost per unit is roughly the same.
Can sofubi figures be painted?
Yes, sofubi figures are painted after production. Base colors are applied with spray guns through masks, and fine details are hand-painted. The soft vinyl surface accepts acrylic and enamel paints well. However, because sofubi is flexible, the paint must also be flexible to avoid cracking when the figure is squeezed.
How do you clean and care for sofubi figures?
Clean sofubi figures with a soft, dry cloth. Avoid water immersion, harsh chemicals, or direct sunlight (which can cause yellowing). Store in a cool, dry place away from heat sources. If the figure becomes sticky (a sign of plasticizer migration), wipe with a small amount of isopropyl alcohol on a cloth.
We produce both sofubi and regular PVC vinyl figures. This comparison comes from 12 years of manufacturing both materials — we know when each one works best and where the trade-offs actually matter.
