This event marks the first time "Accounting & Finance Day" will be held offline, dedicated to those involved in accounting and finance.

This time, with the theme of "Accounting Organizations That Continue to Function," participants will deepen their understanding by comparing their own company's situation and initiatives through real dialogue and exchange of opinions unique to an offline event.

In the accounting field, there is often a situation where there is not enough time or leeway to re-examine the ideal state of the organization while being busy with daily operations.

On the day of the event, Mr. Naofumi Hayashi, General Manager of the Transformation Design Department, Global Accounting Center, Sony Group Corporation, highly regarded as one of Japan's top accounting professionals, will be invited to organize the environment and changes surrounding accounting organizations, and share perspectives and ideas for accounting organizations to function sustainably in the future.

After the lecture, a roundtable discussion will be held for participants to interact with each other. Based on the insights gained from the lecture, this will provide an opportunity to re-examine the current state of their own accounting organizations and gain hints for building a sustainable organization.
