*📜 Plan description

Setup fee: 1,650 JPY unless waived through an eligible simultaneous domain application.
CORE-Z is the top V2 plan for large websites, corporate sites, high-volume WordPress projects, commercial sites, and users who need the highest listed V2 resources plus phone callback support. It includes 1,000 GB of NVMe SSD storage, unlimited transfer in normal use, unlimited hosted domains, unlimited email addresses, unlimited MariaDB databases, free SSL, WordPress support, and 15 backup generations.
The plan has 12 GB RAM allocation and 1200 percent CPU allocation, described as twelve times the resource amount of one CPU core equivalent. It supports up to 4,000,000 files and a daily mail send/receive guideline of 40,000 messages. Phone callback support, contact-form/email support, and live chat are included. Monthly equivalents are 2,490 JPY for subscription billing, 2,178 JPY with 12 months, 2,123 JPY with 24 months, and 1,990 JPY with 36 months.

CORESERVER V2 shared hosting is built for high-speed Linux hosting with cloud-style resource control, LiteSpeed web server, NVMe SSD RAID10 storage, free SSL, HTTP/2 and HTTP/3, Web Application Firewall, IPS/IDS protection, and Imunify360 security. The servers are installed in Japan and connect each server to a large domestic backbone at 10 Gbps. The platform specification lists up to 64 CPU cores and up to 512 GB to 1 TB server memory at the host level, while each plan receives its own listed RAM and CPU allocation.
The in-house control panel includes file management, multi-domain handling, Japanese domain support, subdomains, CRON, URL forwarding, CGI/SSI, Perl, Ruby, Python, .htaccess, sendmail, SQLite, MariaDB 10.6, mail forwarding, webmail, POP/POPS, SMTP/SMTPS, IMAP/IMAPS, virus checking, spam filtering, mailing lists, autoresponders, and FTP/FTPS/SFTP. WordPress can be installed automatically from the control panel, and the service also promotes a free WordPress migration tool for moving existing WordPress sites. A domain can be effectively free when ordered together with eligible V2 hosting, and the setup fee can be waived for eligible simultaneous domain applications. Pricing is tax included and the lowest public monthly equivalent is based on the 36-month term; other billing terms remain available at higher monthly equivalents.
All plans include a 30-day free trial, backup generations, free independent SSL through Let's Encrypt, and support by contact form/email and live chat. Phone callback support is reserved for CORE-Z in the V2 family. Transfer is treated as unlimited up to the defined normal range, with best-effort handling or temporary rate adjustment possible if unusually high traffic places load on the entire server.

📄 Editorial Review

CORESERVER is a Japanese shared/rental hosting brand operated by GMO DigiRock, Inc. (digirock.co.jp), part of the wider GMO Internet Group (group.gmo). The company traces its operating history to July 2001, was incorporated in April 2004, and launched the CoreServer service in August 2007. GMO DigiRock’s wider ecosystem includes domain registration, rental servers, access analytics, server OEM activity, and related hosting brands.

CoreServer is mainly a high-performance shared hosting platform rather than a VPS or dedicated-server provider. The current product line is divided into two major generations: V1 plans and newer V2 plans. The V2 line — CORE-X, CORE-Y, and CORE-Z — is the more modern option, using LiteSpeed, NVMe SSD RAID10, stronger resource allocation, free SSL, WordPress auto-installation, HTTP/3 support, backups, and security features such as Imunify360. These plans are suitable for WordPress sites, business websites, EC sites, and users who want better speed and stability than a basic budget shared host.

The V1 line — CORE-MINI, CORE-A, CORE-B, and CORE-C — remains the more traditional Apache-based shared hosting family. These plans still include SSD storage, WordPress support, free SSL, email, databases, and backups, but the architecture is closer to conventional shared hosting. CORE-MINI has tighter limits, while CORE-A/B/C expand into unlimited domains, mail accounts, and databases.

Domains are handled through Value Domain, the domain-registration platform in the same GMO DigiRock ecosystem. This is important because CoreServer hosting, domain registration, DNS, and SSL management work naturally together. V2 hosting can also include one permanently free eligible domain per server, including extensions such as .com, .net, .org, .info, .biz, and .jp.

SSL coverage is strong for a low-cost Japanese host. Let’s Encrypt certificates are free and can be managed from the CoreServer control panel, while paid SSL options include AlphaSSL, .shop SSL, and GlobalSign corporate SSL. Related GMO DigiRock services such as Value Server and XREA serve nearby market segments, but CoreServer is the higher-performance shared-hosting line.

The platform is clearly oriented toward Japan. The public website is in Japanese, the terms require users to understand Japanese, and applications may be refused where the applicant is not resident in Japan or does not have a base in Japan. For Japanese users, agencies, and businesses targeting Japan, this is a practical and cost-efficient hosting environment. For international users who require English-language support or a globally marketed VPS/cloud product, it is less suitable.
