About 『資産保全学』50,60代の賢い資産の守り方

『資産保全学』(Asset Preservation Studies) is a finance education channel operated by Shogo Bunbu, a certified financial planner and representative director of the General Incorporated Association for Defined Contribution Pension Diagnosis. The channel focuses on wealth preservation strategies tailored to individuals in their 50s and 60s, addressing retirement planning, pension optimization, and financial literacy gaps in Japan's aging demographic.

Bunbu's professional background includes over three years of direct engagement with financial institutions, having conducted training sessions across 165+ branches of major banks and insurance companies, reaching more than 4,000 professionals. He is also the author of "Defined Contribution Pensions: Who Loses and Who Wins with Retirement Funds" (published by Wani Plus), which achieved the #1 weekly bestseller ranking at Maruzen Nihonbashi bookstore.

The channel's content strategy extends beyond YouTube video uploads. Bunbu leverages a LINE community to distribute supplementary resources, including a 50-point retirement anxiety checklist and a visual worksheet for financial review—materials positioned as unavailable through YouTube's standard format. This omnichannel approach reflects a broader monetization and audience-retention strategy common among Japanese financial educators targeting mid-career and pre-retirement demographics.

As of May 2026, the channel has published 55 videos and accumulated 12,038,697 total views across 126,000 subscribers.

『資産保全学』50,60代の賢い資産の守り方's estimated sponsorship rates

Estimated sponsorship rates for integrated YouTube video placements range from $454 (low) to $1,134 (high), with a typical rate of $756 per video. This pricing reflects the creator's mid-tier audience classification within the finance niche.

Several factors influence rate positioning relative to peers of similar subscriber count. First, the Japanese market and Japanese-language content typically command lower CPM (cost per thousand impressions) than English-language finance channels, reflecting advertiser spend concentration in North American and Western European markets. Second, the creator's specific focus on retirement planning and wealth preservation for 50–60-year-old audiences attracts a narrower advertiser pool than broader investment or trading content—limiting competition for ad slots and potentially reducing per-impression rates compared to creators like 【佐々木啓太】投資チャンネル (129,000 subs), whose general investment positioning may appeal to a wider demographic.

Third, the creator's professional credentials (FP certification, published author, corporate training track record) position the channel as educational rather than entertainment-driven, which can either elevate rates among B2B financial services advertisers or reduce rates among consumer-focused brands depending on campaign objectives. The LINE-based community strategy suggests supplementary revenue streams beyond YouTube advertising, potentially affecting negotiated video-integration pricing.

Who should partner with 『資産保全学』50,60代の賢い資産の守り方?

The channel's audience is primarily composed of individuals aged 50–60 in Japan, with secondary reach into pre-retirement (40–50) and early-retirement (60+) demographics. This age concentration is reflected in content themes: defined contribution pension optimization, tax-efficient withdrawal strategies, inflation protection, and estate planning—topics with minimal relevance to younger investors.

Brand categories aligned with this audience profile include: Japanese financial institutions (banks, securities firms, insurance companies), pension and retirement planning platforms, tax advisory services, long-term care insurance providers, real estate investment trusts (REITs) targeting retirees, and healthcare/wellness services marketed to aging populations. The creator's professional network—evidenced by 165+ financial institution training engagements—suggests strong B2B appeal among financial services firms seeking to reach mid-market and high-net-worth clients approaching or in retirement.

Comparable creators in the finance niche, such as SHARRA (127,000 subs) and onvista (128,000 subs), operate in similar subscriber ranges but typically address broader investment audiences. 『資産保全学』's differentiation lies in its explicit age and life-stage targeting, which narrows audience size but increases advertiser relevance for products and services designed for wealth preservation rather than wealth accumulation.

The channel's LINE community integration indicates an audience sufficiently engaged to opt into supplementary communication, suggesting higher-intent viewers and potential for direct-response advertising or lead generation campaigns.

『資産保全学』50,60代の賢い資産の守り方's growth and performance

InfluencerUnion tracking data spans only one day (May 12, 2026), with the channel holding steady at 126,000 subscribers at both the first and latest snapshot. This single-point observation provides no basis for assessing growth trajectory, acceleration, or seasonal patterns. Average view counts over the last 30 days are not yet available in the dataset.

To establish meaningful growth analysis, longitudinal data across multiple months would be required. Interested parties should monitor the channel's subscriber and view metrics over time to identify trends in audience expansion, content performance consistency, and potential correlation with video publication frequency (55 videos published to date) or external events (e.g., media appearances, book promotions, or changes in YouTube algorithm visibility).

How our pricing estimate works for 『資産保全学』50,60代の賢い資産の守り方

Rate estimates are calculated algorithmically using subscriber count, niche-specific CPM (cost per thousand impressions), and platform/format multipliers. The estimate does not incorporate actual negotiated rates, historical pricing data from this creator, or community-reported figures—none of which are available. The basis is metric_estimate with zero calibration data points from direct creator transactions.

The algorithmic model accounts for: (1) baseline subscriber count (126,000), (2) finance niche CPM adjusted for Japanese market conditions and audience age demographics, and (3) YouTube video integration format multipliers. The resulting range ($454–$1,134, typical $756) reflects uncertainty inherent in algorithmic estimation and should be treated as a reference point rather than a binding quote.

For a detailed explanation of the CPM calculation, niche adjustments, and platform multipliers, see the /methodology page. Actual sponsorship negotiations may yield rates significantly above or below this estimate depending on advertiser budget, campaign scope, audience overlap with advertiser targets, and creator negotiating leverage.
