Seiraku Toys is expanding its creator collaboration focus in the U.S. market, pairing Japanese-style product design with talent from various adult entertainment and gaming genres. This initiative aims to provide creators with a path into premium product development and offer fans collectible items tied to personalities and fandoms.

Creator Collaboration Expansion

On August 26, 2026, Seiraku Toys announced an expansion of its creator collaboration program in the U.S. market. The program combines Japanese-style product design with talent from cosplay, VTubing, JAV, adult entertainment, and 18-plus gaming genres. Niels van der Voort, founder and owner of Seiraku Toys parent company MotsuGroup, stated that the goal is to build products that respect both the creator's identity and the customer's desire for fun, well-made items connected to worlds they enjoy. Past and current collaborators include FeFe, LienSue, Mion Hazuki, Luna Amemiya, and Raku, with additional projects in development.

Seiraku Toys develops original molds and product concepts using high-quality TPE and silicone, focusing on soft, durable materials and fantasy-led design. MotsuGroup's international operations support these creator projects, including U.S. fulfillment through Onahole.com, EU fulfillment through MotsuToys.com, and B2B wholesale access through MotsuGroup.com. Seiraku Toys is the premium in-house brand of MotsuGroup, a privately owned European company specializing in Japanese-style male pleasure products, including onaholes, cups, hips, torsos, and accessories. The brand is built around Japanese craftsmanship.

MotsuGroup began in 2008 as a small webshop for Japanese adult toys. It has since grown into a privately owned international operation with consumer platforms in the U.S. and Europe, B2B wholesale access, and creator collaborations spanning cosplayers, VTubers, JAV stars, adult performers, and 18+ game developers. Seiraku Toys and Onahole.com have received attention from adult industry trade media for recent product news as MotsuGroup continues to build its U.S. retail presence.

Design and Innovation

Seiraku Toys is sharpening its U.S. focus through Onahole.com, the company’s American consumer platform for Japanese-style male pleasure products. Created by Niels van der Voort, Seiraku Toys reflects MotsuGroup’s work in Japanese adult products, combining anime and manga-inspired aesthetics with premium materials, original molds, and product concepts. These products are developed for fans of Japanese culture, creator fandom, and elevated fantasy design. The product line includes onaholes, cups, hips, torsos, and accessories, with U.S. orders fulfilled through Onahole.com’s warehouse in Boise, Idaho.

Van der Voort stated that Seiraku Toys represents the culmination of years of product knowledge, Japanese adult toy culture, and the company's own design ideas. He noted that the U.S. market has been important to MotsuGroup for a long time, and this push aims to provide American customers with a clearer path to the products, creators, and quality behind the brand. MotsuGroup's creations are designed in-house with the goal of setting the standard for male pleasure, ranging from compact essentials to full-sized experiences, reflecting innovation, quality, and an understanding of male preferences. The company's catalog features internal bone structure, realistic touch material, and ultra-realistic entry.

By 2019, MotsuGroup identified a gap in the market where traditional Japanese brands were lagging in innovation. In response, MotsuGroup partnered with Japanese artists and designers to launch XTC Japan and Seiraku Toys, brands dedicated to delivering high-quality, immersive experiences in male pleasure. MotsuGroup states that its products have outsold mainstream brands in top adult stores worldwide and are considered game changers in adult retail. The company offers exclusive Japanese brands, high margins, competitive pricing, reliable supply, fast shipping, and B2B support with marketing insights to retailers.

Japanese Expertise in Product Development

The design process for Seiraku Toys products, including onaholes, is guided by Japanese expertise. Every Seiraku project begins with a team of Japanese designers, sculptors, and engineers. This team conducts research, studying user feedback, experimenting with new stimulation methods, and exploring materials. The objective is to create sensations and experiences that are distinctly Seiraku, rather than replicating existing products.

Once an idea is formed, designers sketch multiple concepts, experimenting with tunnel structures, textures, and suction patterns. Sculptors then create a clay prototype to establish the overall shape, proportions, and surface details. After the clay model captures the desired form and texture, a wax model is used to refine finer details, perfect symmetry, and finalize the design before casting the production mold. Subsequently, the design transitions to 3D modeling, where engineers fine-tune precision, balance, and durability. Most of the design and engineering takes place in Japan, ensuring craftsmanship and attention to detail. This process aims to produce a collection of onaholes that blend artistry and technology to create products that are natural, ergonomic, and unique.
