The design of the Campaign Management Tool for Display Ads has been updated. The simpler, more intuitive interface provides a more comfortable user experience when managing your ads.
As of October 20, only some screens in the Campaign Management Tool have been updated to the new design. Other screens will be updated gradually.

The "Shift_JIS" character encoding option is no longer available for CSV downloads, including data files used for importing into Display Ads.
Use other character encodings, such as "UTF-8," going forward.

Files used with the import feature can still use the "Shift_JIS" character encoding.
However, support for "Shift_JIS" in the import feature is also scheduled to end in the future. We recommend considering other character encodings. The discontinuation date will be announced once confirmed.

The filter items for estimated user age and gender, which were discontinued in October 2021, and the legacy age categories have been removed.

The recommended browser for the Campaign Management Tool has been changed to "Google Chrome" only.
Other browsers, including "Microsoft Edge," "Firefox," and "Safari," are no longer included in the recommended environment.
