What It Is

カスタムライフ（Customlife） is a web media and digital marketing company based in Tokyo, Japan. Its business spans from operating its own media properties to content marketing, SEO consulting, Instagram operations, web advertising, website production/maintenance, and its in-house Headless CMS, 「BERYL」. Rather than being a standalone SEO tool, it is positioned as a service-led Japanese content and growth support provider.

Core Capabilities and Data Foundation

Its core selling point comes from hands-on experience running its own media. The disclosed figures include more than 10 years of media operations, the launch of over 10 media sites, and annual traffic of 50 million PV. Its content production process emphasizes user interviews, SNS research, competitor analysis, expert interviews, access/visitor surveys, questionnaires, and product/service verification. This makes it suitable for companies that need high-quality long-form Japanese content, YMYL content, product reviews, and ongoing updates. Its SEO services cover keyword selection, content structure design, article production, CMS publishing, maintenance updates, competitive analysis, and more. Its Instagram services include account audits, content strategy, posting plans, hashtag strategy, advertising recommendations, monthly reports, and outsourced account operations.

Pricing and Delivery

Public pricing is relatively detailed: keyword selection starts from 300,000 JPY per session; article structure starts from 30,000 JPY per article; article production starts from 25,000 JPY per article with a minimum of 5 articles; maintenance starts from 200,000 JPY per month. SEO starts from an initial fee of 300,000 JPY plus a monthly fee of 300,000 JPY, typically under a 6–12 month contract. Ad operations are charged at 20% of ad spend; LP production starts from 200,000 JPY; website production starts from 500,000 JPY. Overall, this is professional-service pricing in the Japanese market, leaning toward project-based and consulting-based engagements, and is best suited to businesses with a clear budget.

Pros and Cons

The advantages are its complete service chain, with one-stop support across content, SEO, SNS, advertising, and website production, plus the credibility of in-house media experience and full-time writers. The drawbacks are that public case-study details are limited, many implementation examples appear to be logo placeholders, the FAQ still contains placeholder text, and some prices are only starting prices, meaning actual costs require inquiry. SEO and Instagram consulting also involve relatively long contract periods.

Best Fit and Access from China

It is best suited to brands, media companies, and e-commerce/service businesses targeting the Japanese market that need Japanese SEO content, Instagram operations, or ad placement. If the goal is mainland China search, WeChat, Xiaohongshu, Douyin, or similar ecosystems, the available text does not show relevant localization capabilities, so it is better to prioritize evaluation of China-based service providers. Access from mainland China and supported payment methods are not disclosed in the text and should be treated as unknown. Before cross-border cooperation, confirm online communication channels, contract currency, invoicing, and payment methods.
