We have updated the way addresses are registered on Otsukai. All addresses now require both a complete street address and a city name. Due to the importance of this system change, we require all users to go to the 'Change address' page on their My Page and confirm that their address is being displayed correctly, and to make any necessary amendments before making any more purchases on Otsukai.
This is to prevent cases such as users requesting their address be changed after beginning an Errand, which runs the risk of their items being shipped to an incomplete or invalid address.
If you have any questions or queries regarding this change, please do not hesitate to contact the Otsukai support team and we will get back to you as soon as we can.
