Thunderbird has 11.5% share in Japan

IT Pro Research today published a survey of 1781 email users in Japan. It’s not exactly clear who they were surveying (I am assuming enterprise/business users but…) so this is certainly not gospel.


Unsurprisingly, the total usage of Windows (from 98 through to Vista) is 96.8%. I know Macintosh has a larger than 2.1% share in Japan so this data is skewed towards business users I think.

The share of email clients is much more interesting and Thunderbird has an 11.5% share. Webmail has a 7% share.

If one was to do a general survey of Japanese Internet users, I’m sure the webmail percentage would be much higher and I’m sure there are many, like me, who use both a client and webmail.

NTT DoCoMo ISP ‘mopera U’ promotes Thunderbird

Of the mobile phone network providers in Japan, NTT DoCoMo (Wikipedia) is the largest provider and has the broadest mobile network in Japan.  DoCoMo provides Internet access services for those people who require PC-based wireless broadband access to the Internet via DoCoMo’s ‘mopera U‘ subsidiary.

Last week NTT DoCoMo’s mopera U annouced an add on for Mozilla Thunderbird which configures Thunderbird with the settings for mopera U.  The user only needs to know their email address and password (the tool configures the other server/proxy/smtp/etc. information.)


Another major ISP in Japan, IIJ, has been distributing a customized Thunderbird for their users since 2006.

While the popularity of webmail is clear, there will always be a need for a mail client and I (and the many loyal Thunderbird uses in Japan) look forward to the actions of the new Mozilla Messaging organization.
