Conclusion: a fit for business email and controlled multi-site operations
CPI is best evaluated as an operational package for corporate websites and email rather than as a budget hosting plan. The official specification lists 300 GB of SSD storage for the primary web domain and up to ten multi-domain environments, each with a separate 100 GB web area.
Its differentiators are SmartRelease staging and deployment, separated web and mail infrastructure, SPF, DKIM and DMARC support, and a defined SLA scope. Buyers should distinguish standard features from paid options before signing a contract.

Pricing and contract terms
The official pricing page lists three, six, and twelve-month terms. At the verification date, the twelve-month term was displayed at JPY 4,840 per month equivalent, JPY 58,080 in total, with no setup fee. Shorter terms had a higher monthly equivalent and a setup fee.
Prices, taxes, and optional services may change. Confirm the checkout screen and contract documents before purchase.
| Term | Monthly equivalent | Term total | Setup fee |
|---|---|---|---|
| 12 months | JPY 4,840 | JPY 58,080 | No charge |
| 6 months | JPY 5,170 | JPY 31,020 | JPY 22,000 |
| 3 months | JPY 5,500 | JPY 16,500 | JPY 22,000 |
Website operations and SmartRelease
SmartRelease combines a test environment, controlled production release, backup, and recovery workflows. This is useful when a company needs a review step before publishing changes or when an agency manages client websites.
The standard SmartRelease backup is limited to a combined 10 GB of web files and databases for up to 30 generations. The 300 GB primary web capacity does not mean that the entire capacity is retained for 30 generations.
Email, security and SLA scope
The mail service supports SPF, DKIM and DMARC, along with webmail, forwarding, autoresponders and mailing lists. WAF and a CPI SSL certificate are included, while website tamper detection is listed as a paid option.
The SLA uses a 100 percent service-level reference for the primary web server. The official specification excludes the mail server and servers used for multi-domain environments from that SLA scope.
Support and migration considerations
Standard support is email-based. The 24-hour telephone and email service is a paid option. Migration assistance may also involve paid work, so the organization should document who handles data transfer, testing, DNS changes, and rollback.
CPI also publishes trial and refund conditions. Review exclusions, deadlines, and domain-related charges directly in the current policy before relying on a refund option.
Who should consider CPI
CPI is relevant to Japanese companies, organizations, and web agencies that value business email, multi-domain isolation, staging, and recovery procedures. A low-cost shared host may be better for one small personal site, while a VPS or managed dedicated service may be better when root access or isolated compute resources are required.
