Yuka is a creator with a presence on YouTube (142,000 followers), Instagram (837,175 followers), based in United States. Their content sits in the tech & creativity space. Their YouTube bio reads: "Hey, I’m Yuka! I make videos about tech and creativity—from hands-on gear reviews to workflow hacks and behind-the-scenes creator life. If you're into thoughtful gadgets, smarter setups, and finding fun ways to stay inspired, you’ll feel r". The full audience and engagement breakdown is below.
Yuka reaches an audience concentrated in United States primarily through YouTube, and is best activated via long-form YouTube integrations, Instagram Reels and Stories. Their sponsorship history skews toward Beverages / Lifestyle, Beauty / Fragrance, a clear signal of fit for brands in those categories. Demonstrated partners include Rokid and Insta360. Engagement on YouTube runs around 2.9%, which points to an audience better suited to category-relevant, mid-funnel campaigns than to pure-reach buys. The channel's mix of long-form YouTube integrations and Instagram Reels and Stories lets a sponsor choose between short awareness placements and longer, more detailed integrations. Because the audience follows tech content rather than arriving through untargeted reach, sponsorships that match the channel's subject matter tend to convert more efficiently than broad placements. A consistent, on-topic posting focus gives sponsors a predictable, brand-safe environment, lowering placement risk compared with broad, general-interest channels. Campaigns here are best measured on qualified engagement and consideration within the niche rather than on raw impression volume. For United States-focused brands in Beverages / Lifestyle and related categories, Yuka offers a defined, creative-fit audience rather than broad, low-intent impressions.

Yuka's full name is 萬波 ユカ (Manba Yuka), as she lists it in her Instagram bio. She uses the single name Yuka across her creator platforms, keeping her persona consistent whether she's posting gadget reviews on YouTube or lifestyle content in Tokyo.
Yes, Yuka is represented by Donna Models Japan (@donnamodels.jp), a Tokyo-based modeling agency. She runs both careers in parallel — her modeling work based in Tokyo and her YouTube channel focused on tech, gadgets, and creator workflows.
ユカスタ is Yuka's signature content brand, built around smartphone customization, aesthetic tech setups, and personal style systems. She uses it as a recurring hashtag across posts and has extended it into a dedicated podcast format called the ユカスタポッドキャスト.
Yes, Yuka hosts the ユカスタポッドキャスト, promoted with its own dedicated hashtag. It sits alongside her YouTube channel as part of her broader content universe covering tech, creativity, and creator life — all aimed at a Japanese-speaking audience.
Notion is a recurring theme in Yuka's content — she uses the hashtag #まいにちnotion, which translates to 'daily Notion,' across her posts. Workflow hacks and productivity setups built around Notion are among her signature YouTube topics.
Yuka partnered with Rokid, the AR glasses and mixed-reality device brand, for sponsored content on YouTube in 2026. The collaboration fits her gadget-review niche and sits alongside her tech partnerships with Insta360 and Casetify.
Yes, Yuka was invited to the Japanese launch of Dior's alcohol-free fragrance line, which she covered on Instagram. She described the scent as having a fresh, milky mist quality — like arranging fresh flowers in a vase — indicating she moves in luxury brand circles beyond her tech content.
Casetify is one of Yuka's named sponsors, with dedicated YouTube sponsored content and some of her top-used hashtags (#casetify, #ケースティファイ). The phone case brand aligns directly with her iPhone tips and smartphone setup content, making it one of her most thematically on-brand deals.
Yuka partnered with Insta360 for sponsored YouTube content in early 2026. As a creator who covers gadgets, behind-the-scenes creator life, and hands-on gear reviews, an action and 360 camera brand is a natural fit for her channel.
Yuka's content is primarily in Japanese — over 85% of her audience is based in Japan, making her one of the stronger Japanese-language tech and lifestyle creators in the mid-tier space. Her iPhone tips, Notion workflows, and gadget reviews are all delivered in Japanese, with a small international following in the US, Taiwan, and South Korea.
