Reviews and expert opinion Data Japan

Gwen Rodgers Gwen Rodgers Web Hosting Expert

Data Japan is a long-standing Japanese business that sells Windows shared hosting and WordPress hosting plans. The prices are high, the contact channels are limited, but the knowledge base is good.

Data Japan has been in business since 1991, but it began selling shared hosting in 1999 and added dedicated servers in the year 2000. This host’s Japanese website looks a little dated and somewhat messy (especially when translated into English).

Features and Ease of Use 

Data Japan sells a range of hosting services, including Windows shared hosting, WordPress-specific plans, and domain registration. Its WordPress packages provide these core features:

  • Automatic WordPress updates
  • Up to ten domains and ten staging sites
  • Automatic backups
  • Domain registration
  • Free Let’s Encrypt SSL certificate
  • Cloud CDN 

Data Japan offers a Secured WordPress Hosting package that includes a three-stage defense system: firewall, web application firewall, and automatic WordPress updatesThe website also alludes to a WordPress dedicated service, but it doesn’t go into any more detail about what this means. 

Besides WordPress hosting, Data Japan sells Windows shared hosting plans which not all hosts offer. These plans come with the Plesk Onyx control panel that provides functionality for creating websites, databases, and email accounts. You also get support for various programming languages (such as PHP, Ruby, and Python) plus ASP.NET, MS SQL, and MySQL with phpMyAdmin.

Pricing and Support 

Data Japan’s prices are high; far higher than international competitors, but arguably in line with other Japanese hosts. And you do get a free SSL certificate, although you have to pay for a domain. You can purchase the plans on one, three, six, or twelve-month terms, with discounted prices for longer-term commitments.

Contact options appear to be limited to an online contact form, but digging deeper into specific services (e.g., the “DataWeb” Windows shared hosting) reveals additional email and support ticket submission options.

For self-support, there is a surprisingly comprehensive knowledge base:
