Registration requires a current valid JTU membership ID for the year 2017. Please visit the JTU site and register as a member of your local prefecture before filling out the Osaka Castle Triathlon 2017 registration form.
Non-Japanese residents may use a one-day membership if you do not have a 2017 JTU annual membership. The one-day membership can be purchased when you sign up using our registration form for non-resident participants. This option will be available soon on this website.
