About 上水流 宇宙 / Cosmo Kamizuru 【ヴイアラ】…

上水流 宇宙 (Cosmo Kamizuru) is a Japanese virtual idol and content creator operating under the PROJECT IM@S vα-liv initiative, affiliated with 876 Pro. The channel focuses on idol entertainment content, streaming, and community engagement centered around the idol-cultivation concept. With 129,000 subscribers and 39.1 million total views accumulated across 893 published videos, the channel represents an established presence within the Japanese virtual idol and entertainment streaming ecosystem.

The creator's stated mission emphasizes entertainment delivery and aspiration toward top-tier idol status, with branding built around space and cosmic themes (宇宙, cosmo). The channel maintains structured community interaction through membership programs, fan art tags (#宇宙の輝き), and dedicated hashtags for streaming content (#宇宙観測). Content distribution extends across YouTube, Twitter, and official PROJECT IM@S platforms, indicating a multi-channel strategy typical of organized idol-project creators.

The channel operates within a formal project structure rather than as an independent creator, which shapes content consistency, scheduling, and brand partnerships. This organizational backing typically correlates with more predictable upload cadence and professional production standards compared to solo creators at similar subscriber counts.

上水流 宇宙 / Cosmo Kamizuru 【ヴイアラ】…'s estimated sponsorship rates

Estimated integration rates for a single YouTube video range from $186 (low) to $310 (typical) to $464 (high), based on algorithmic analysis of the 129,000-subscriber audience and entertainment category positioning. The creator falls into the mid-tier audience classification.

Rate positioning reflects several factors: subscriber count places the channel at parity with direct peers such as 10 Phút Review (130,000 subs) and Chota Youtuber (131,000 subs), all operating in the 124,000–132,000 subscriber band. Within the entertainment category, niche CPM varies based on audience geography, content format, and advertiser demand. Japanese-language entertainment content targeting domestic audiences typically commands different CPM rates than English-language equivalents, influenced by regional advertising spend and brand-category concentration.

The mid-tier classification indicates the channel has moved beyond micro-influencer pricing but has not yet reached the premium rates associated with 500,000+ subscriber channels. Virtual idol and anime-adjacent entertainment content attracts specific brand categories—gaming platforms, anime merchandise, streaming services, and entertainment apps—which can support competitive rates within the entertainment vertical. The estimate carries a calibration note of zero community data points, meaning rates are derived from algorithmic modeling rather than reported brand deals or creator disclosures.

Who should partner with 上水流 宇宙 / Cosmo Kamizuru 【ヴイアラ】…?

The channel's 129,000 subscribers and 39.1 million cumulative views indicate an audience primarily engaged with Japanese virtual idol content and organized entertainment projects. The audience composition aligns with fans of PROJECT IM@S properties and idol-cultivation entertainment, a niche with distinct demographic and psychographic characteristics.

Brand-relevant categories for this audience include anime and gaming merchandise retailers, streaming platforms specializing in idol or anime content, gaming applications with idol or character-driven narratives, and entertainment merchandise distributors. The formal project structure suggests audience members are often invested in multi-creator ecosystems—fans typically follow multiple idols within the same project, creating cross-promotion opportunities and bundled sponsorship potential.

The channel's community infrastructure—membership programs, fan art tags (#宇宙の輝き), and dedicated hashtags (#宇宙観測)—indicates an audience actively participating in fan creation and community rituals. This level of engagement typically correlates with higher brand affinity and willingness to engage with sponsor content, particularly when sponsorships align with entertainment, gaming, or lifestyle categories relevant to idol-fan demographics.

Peers operating at similar scale (10 Phút Review at 130,000 subs, LIVIANA Ch. at 132,000 subs) serve comparable audience tiers, though geographic and content-category differences mean direct audience overlap varies. The Japanese domestic focus and virtual idol specialization create a distinct audience segment compared to broader entertainment channels.

上水流 宇宙 / Cosmo Kamizuru 【ヴイアラ】…'s growth and performance

Snapshot data spans a single day (May 11, 2026), with the channel holding 129,000 subscribers at both the first tracked date and the latest observation. This one-day window provides insufficient data to assess growth trajectory, velocity, or seasonal patterns. Average view counts for the last 30 days are not yet available in the dataset.

To establish meaningful growth metrics, longitudinal tracking across weeks or months would be required. Channels in the 120,000–130,000 subscriber range typically exhibit variable growth patterns depending on content release frequency, project-level promotional activity, and community engagement cycles. The 893 published videos suggest consistent output over the channel's operational history, though publication dates and frequency distribution are not provided. Future snapshots will enable analysis of subscriber acquisition rate, view-per-video trends, and seasonal fluctuations.

How our pricing estimate works for 上水流 宇宙 / Cosmo Kamizuru 【ヴイアラ】…

Rate estimates are generated algorithmically using subscriber count, category-based niche CPM benchmarks, and platform/format multipliers. The calculation does not rely on reported brand-deal pricing or creator disclosures. The estimate is calibrated against zero community data points, meaning no verified rates from this creator or closely matched peers inform the model—the figure is derived from statistical modeling of the entertainment category and mid-tier audience segment.

For a detailed explanation of the CPM assumptions, multiplier methodology, and confidence intervals, see the /methodology page. Actual rates depend on factors including campaign scope, exclusivity terms, audience geography verification, and brand category. Creators should treat algorithmic estimates as reference points rather than binding quotes; direct outreach to the creator or representation is necessary for accurate rate information.
