Tantaly RUKA MOMOTO Japanese Sex Doll with Tantabosom

An Officially Licensed Japanese Figure

Ruka Momoto is Tantaly’s first Japanese doll, developed under official adult authorisation with performer Ruka Momoto of Obokozu. The body faithfully recreates her curves and the features of an adult Japanese woman for a highly realistic likeness.

Lifelike Intimate Detailing

Ruka is finished with careful intimate detailing, including a textured vaginal canal with soft, folded labia and a comfortable anal passage. With enough water-based lubricant, both entries deliver a snug, realistic sensation.

Suitable for a Wide Range of Positions

Ruka’s full body and shaped thighs support different styles of solo play, including missionary, doggy-style, and cowgirl-style setups. Her weight keeps her grounded and lifelike during use.

Tantaly's Soft Breast Technology - Tantabosom

Ruka features Tantabosom, Tantaly’s exclusive soft breast design that is more than 30 percent softer than regular gel breasts. Her soft, teardrop-shaped bust has a natural bounce and full, detailed nipples, making her well suited to breast play and hands-on sessions.

Frequently Asked Questions

Is Ruka Momoto an officially licensed doll?

Yes. Ruka Momoto is an officially licensed collaboration between Tantaly and Japanese adult performer Ruka Momoto of Obokozu. The doll is developed under adult authorisation and recreates her likeness in a realistic body-style design.

Is Ruka Momoto a Japanese sex doll?

Yes. Ruka Momoto is Tantaly’s first Japanese doll. The body recreates the curves and features of an adult Japanese woman for a highly realistic, life-like figure.

What is Tantabosom?

Tantabosom is Tantaly’s exclusive soft breast technology. It is more than 30 percent softer than standard gel breasts and is designed to give a soft, natural feel with realistic movement, while keeping its shape over time.

Does Ruka have a removable vagina?

No. Ruka has a built-in vaginal canal and a built-in anal canal. Both are fixed to the body rather than removable, so clean them in place after each session.

Can Ruka be used for both vaginal and anal play?

Yes. Ruka has a dual-entry design with both vaginal and anal openings. Use plenty of water-based lubricant and take your time, especially with rear-entry play.

Is Ruka a full-body sex doll?

No. Ruka is a body-style doll. She includes the upper body, bust, waist, hips, and thighs, with vaginal and anal openings, but does not have a head, arms, or full legs. This makes her easier to move, clean, and store than a life-size doll.

Are Tantaly dolls safe?

Yes. Tantaly dolls use medical-grade TPE that is certified to CE and RoHS standards and is free of harmful substances. The material is designed to be non-toxic and suitable for long-term use with proper care.

How do I care for Ruka's breasts?

Handle the bust gently and avoid heavy squeezing, twisting, or prolonged pressure on one side. Store Ruka with the breasts facing upward where possible. Avoid tight or dark clothing for long periods, as this may place pressure on the TPE or cause staining.

How heavy is Ruka?

Ruka has a net weight of 45 lb / 20.4 kg. Her gross packaged weight is 55.8 lb / 25.3 kg. She has a solid feel, so make sure you have enough space and the strength to move her safely.

What is Ruka made from?

Ruka is made from soft, body-safe TPE. This gives her a flexible, skin-like feel and helps create realistic touch, pressure, and body contouring during use.

What lubricant should I use with Ruka?

Use water-based lubricant only. Water-based lube is safer for TPE and helps protect the material during use. Avoid silicone-based and oil-based lubricants, as they may damage the surface.

How do I clean Ruka after use?

Clean Ruka after every session with warm water and a gentle toy cleaner suitable for TPE. Rinse the entry points carefully, dry her fully, and apply renewal powder if needed to keep the surface soft and smooth.

How should I store Ruka?

Store Ruka in a cool, dry place away from direct sunlight. Keep prolonged pressure off the body. Where possible, store her in her protective packaging or a suitable storage bag to help protect her shape.

How long does a TPE doll like Ruka last?

The lifespan depends on use, cleaning, and storage. With proper care and normal use, TPE dolls typically last around 6 to 18 months. To help Ruka last longer, clean her after each use, dry her fully, use water-based lubricant only, and store her in a cool, dry place away from direct sunlight.
