168cm/5ft6 B-Cup Japanese Tall Silicone Sex Doll – S16 Yu: Some Honest Thoughts

When Curiosity Gets the Best of You

It’s weird, right? The first time you find yourself actually considering buying a tall, silicone sex doll—like this 168cm (5’6”) B-cup Japanese sex doll called S16 Yu. If you're exploring quality japanese sex doll, you'll find plenty of options worth considering. I remember thinking, “Am I really doing this?” But then again, after reading through endless TDF threads and seeing how open people were about their experiences… it kind of normalized things. Not that I’d ever admit that to my coworkers.

Details That Actually Matter (Or Don’t)

You see the product photos and those staged factory shots, but when you’re staring at the specs—full body silicone, B-cup, bubble butt (yeah they use that term), weight around 79-88 lbs—you start wondering what’s real. Is she going to look like the pictures?

There’s always a note somewhere saying stuff like: “NOTE: The doll shown in the reviews is the same brand and size as the doll you are viewing. Her head is #S20.” Which means… basically everything is identical except for her head and maybe some skin tone or outfit changes. It shouldn’t matter much but somehow it does. It’s probably just psychological.

A Bit About Heads—And Why They Matter More Than You’d Think

The S20 head—well, mine was S16 Yu but let me tangent for a second because this tripped me up—is soft silicone now. That sounds good on paper (“fantastic oral function,” they say) but there’s a trade-off: eye movement isn’t as easy as with hard heads. Semi-sphere eyeballs versus more adjustable ones; who knew this would be something I’d care about?

I got stuck reading one review where someone complained about UPS taking forever to deliver their hard silicone head. Honestly made me grateful mine came within two weeks.

The Makeup Thing

Factory makeup is… mostly fine? Sometimes a little too perfect or expressionless out of the box. There was a guy on Doll Forum who used FaceApp to add a smile to his Chloe (same model), which looked almost uncanny next to photos of her original face straight from Irontech Doll’s factory.

Me? I just dabbed on a bit of extra blush because she looked pale under my apartment lighting—a tiny detail but it helped make her seem less mannequin-ish.

Living With A Tall Sex Doll

Here’s something nobody mentions enough: 168cm/5’6” is not short for an object you have to move around your place. She weighs in at nearly 40kg—that’s heavier than you expect until you try dressing her or changing positions for photos or whatever else.

But honestly, once she’s set up… yeah, there are moments where it feels oddly comforting just having her there in the room—even if most days she just sits quietly by my bookshelf wearing whatever leftover hoodie I’m not using.

Quirks and Contradictions

Is it all perfect? No way. For example: Soft heads feel nicer if you’re into realism during certain activities (you know which ones), but then adjusting her eyes feels awkwardly old-school compared to newer models with magnetic systems or more advanced robotics—which exist now apparently?

And while this japanese sex doll looks cute and high quality in daylight, sometimes under harsh light she can look slightly too shiny—almost plastic-y—but maybe that’s just me nitpicking.

Oh—and don’t get me started on storing clothing; anything dark-colored will stain unless you wash it first (learned that one fast).

What Stuck With Me

There was one night—I guess this might sound silly—I caught myself talking out loud while setting up her wig before bed. Not like deep conversation or anything dramatic; just muttering about how tangled synthetic hair gets for no reason at all.

For some reason that moment stuck with me more than anything else about owning an ai robot sex doll or full body sex doll or whatever keyword fits here best.

Anyway—

Would I Recommend?

Depends what you want out of it. If you’re looking for something custom—a tall japanese sex doll with small breasts and decent realism—the S16 Yu model hits most marks without feeling cheap or uncanny valley territory (at least after some tweaks). Just brace yourself for shipping times and maybe invest in better lighting if you plan on taking any photos worth sharing online.

Not sure if anyone really needs these things—but after living with one awhile… well, let’s say my perspective shifted more than expected. Maybe yours would too—or maybe you'd end up wishing dolls could do laundry instead of just sitting around looking pretty.

Guess that's still science fiction—for now anyway.
