Xserver is one of Japan’s most established shared hosting providers, operated by XServer, Inc., with a server environment tuned specifically for WordPress.

The hardware pairs 5th-generation AMD EPYC CPUs with NVMe RAID10 storage, and the WordPress runtime uses KUSANAGI-grade tuning — one of the fastest known WordPress execution environments. Beginner-friendly tools round out the setup: one-click WordPress Quick Start, automatic domain and SSL setup, and WordPress Recovery, which resets a site to a working state when something breaks. Daily backups of server data and the MySQL database are kept automatically, and restores are available.

Security is included on every plan: a Web Application Firewall and DDoS protection filter malicious traffic before it reaches the site.

Xserver also auto-installs popular Japanese WordPress themes such as Cocoon and Lightning, and sponsors the developer of Cocoon to keep the server environment optimized for that theme.

Japanese-language customer support is available year-round by phone and email.
