Irokebijin Doll Guide: HSS Silicone, S-TPE Bodies, Heads and Custom Options
Choosing an Irokebijin doll is easier when you understand how the range is built. Body material, height, head category and custom options all affect the final look, feel and handling.
This Irokebijin doll guide explains the difference between HSS Silicone and S-TPE bodies, how mini heads and regular heads work, and which options are worth checking before choosing your model.
For model-by-model recommendations, read ourย Best Irokebijin Sex Dolls Guide. This guide looks at the practical details behind the range: materials, sizes, head compatibility and practical customisation.
What Makes Irokebijin Different?
Irokebijin is designed by Mizuwali, whose anime-inspired style gives the brand its recognisable look. The range is built around expressive faces, compact-to-full-size bodies and a consistent visual identity across different materials.
That consistency matters. The face, body shape and proportions are designed to work together, so choosing the right head category and body size makes a visible difference.
The two main body materials are:
- HSS Hyper Soft Silicone
- S-TPE
Both support Mizuwaliโs anime design language, but they differ in touch, weight, handling, functional options and care.
Irokebijin HSS Silicone Bodies
HSS means Hyper Soft Silicone. In the Irokebijin range, it is the softer silicone option, made to feel more elastic than standard silicone while keeping the cleaner finish and easier care many silicone buyers prefer.
HSS Silicone is a good choice if you want sharper sculpt detail, a more structured finish and easier long-term maintenance. It also suits collectors who care about display, styling and visual definition.
HSS Silicone Functional Notes
In HSS Silicone, functionality changes by height.
Bodies from 120cm and above include both vaginal and anal channels. Bodies below 120cm include a vaginal channel only.
Smaller HSS Silicone bodies are easier to move, store and style. The 120cm and larger formats offer more presence and a more complete functional layout.
HSS Silicone Included and Optional Features
HSS Silicone configurations may include:
- EVO skeleton
- Gel breasts for medium or big breast dolls
- Hard hands
- Hard standing feet
- Built-in vaginal design only
Additional options may include:
- Implanted hair
- Extra wig
- Extra glass eyeballs
- Articulated fingers
Articulated fingers are one of the most practical upgrades. They make posing easier and help reduce stress on the hand material when dressing, repositioning or setting up photos.
Irokebijin S-TPE Bodies
S-TPE is the softer, more flexible material in the Irokebijin range. Compared with HSS Silicone, it usually feels softer in hand and gives the body more flexibility, but it also needs more careful cleaning, drying and powdering.
S-TPE is a strong choice if softness, body variety and flexible handling matter most. It also gives you the widest spread of formats, from the 86cm torso to taller full-size bodies.
S-TPE bodies include both vaginal and anal channels across the available range. Compact sizes use a built-in vaginal design, while insert options are available for dolls 120cm and above. Always check the current product listing before ordering.
This makes S-TPE the more complete functional option across both compact and full-size bodies. The trade-off is care. S-TPE needs more attention after cleaning and should be dried and powdered properly to keep the surface in good condition.
S-TPE Included and Optional Features
S-TPE standard configurations include:
- EVO skeleton
- Gel breasts for medium or big breast dolls
- Standing feet
- Built-in vagina for all dolls
- Insert vaginal options for dolls 120cm and above
Compact S-TPE bodies may have more limited removable-part options than larger bodies, so check the current product listing, and if you have any doubts contact our team directly.
Additional options may include:
- Extra wig
- Movable eyes
- Glass eyeballs
- Extra inserts
- Pubic hair patch
- Flight case
- Articulated fingers
Articulated fingers are available for all Irokebijin dolls and are one of the most useful upgrades for dressing, posing and long-term handling.

Head Compatibility: Regular Heads and Mini Heads
Irokebijin uses two head categories:
- Regular heads
- Mini heads
You do not need to memorise every head name before choosing. The current HSS Silicone and S-TPE head designs are easier to compare visually through the catalogue images.
Start with head category. Bodies measuring 102cm and below use mini heads. Bodies measuring 120cm and above use regular heads.
This keeps the proportions balanced. Head size changes the full impression of the doll, including facial expression, silhouette and character style.

HSS Silicone vs S-TPE Head Function
HSS Silicone heads do not include an oral channel. Open-mouth HSS Silicone heads feature a kissable mouth design, while closed-mouth HSS Silicone heads are intened primarly for display and styling (non-functional).
S-TPE heads include an oral channel on regular models, except mini dolls measuring 102cm and below.
The S-TPE Koharu model is available with either a regular Irokebijin head or the *Irokebijin Mirai โPlay & Displayโ Head. The Mirai version combines removable moving eyes, a 3D eyelash block and a detachable mouth, allowing buyers to switch between a more expressive display setup and a functional play configuration.
Watch the Irokebijin Mirai Head System Demo to see how the Play & Display head switches between display styling and functional use.
How to Choose a Balanced Head and Body Combination
Start with body size. If you choose a compact body measuring 102cm or below, stay with mini heads. If you choose a 120cm or larger body, choose from the regular head range.
Then choose the face sculpt that matches the character style you want. The same body can look softer, sharper, cuter or more mature depending on the head, eye shape, mouth design and wig.
A simple order works best:
- Choose body size
- Choose material
- Match the correct head category
- Choose the face and styling
Final pairings may depend on current availability and factory confirmation.

Irokebijin Review Notes: What Matters Before Buying
This practical Irokebijin review focuses on the points that affect the final choice.
One of Irokebijinโs strongest points is visual consistency. Mizuwaliโs anime-inspired direction carries across compact dolls, mid-size bodies and full-size formats, so the range feels coherent.
Material choice is another reason the range needs a closer look. HSS Silicone gives a cleaner finish, stronger durability and easier care. S-TPE gives a softer, more flexible feel and broader functional options across the range.
Head and body pairing is where many buyers need the most guidance. Once you understand mini heads and regular heads, it becomes much easier to choose a balanced configuration.
If available, articulated fingers are worth considering. They make dressing, posing and repositioning easier, especially if you plan to change outfits or create photo setups.
Irokebijin is a good fit if you want anime styling, a clear visual identity, different material options and enough flexibility to choose a body and head combination that feels right for your setup.
Final Thoughts
Choosing an Irokebijin doll becomes much simpler once you understand the range.
Choose HSS Silicone if you want cleaner surface detail, easier care and a more structured finish. Choose S-TPE if you prefer softness, flexibility and broader functional options across different body sizes.
From there, choose the body size that suits your handling needs, match it with the correct head category, and check the available options before ordering.
