**Our Vision for this Event** Amidst significant changes in the corporate environment, the roles required of accounting firms are also beginning to shift. In the financial world, the concept of "business valuation," which does not rely solely on collateral or guarantees, is spreading, and discussions about companies' future prospects and value are accelerating.

From now on, it will become commonplace for companies, financial institutions, and accounting firms to collaborate and discuss the current state and future of businesses.

What roles are expected of accounting firms in the future? Beyond just reporting numbers, they must become entities that interpret the background behind them and support decision-making.

How will this value be put into practice?

There are already accounting firms that are creating new value by discussing the future with business owners and supporting their management decisions.

At this event, we will explore the future of accounting firms together, touching upon these practical examples. Accounting firms that can "together" envision the future with business owners will move towards the next standard.

At the forefront of this, at Optimal Value Day.

**About this Event** Our highly acclaimed event for the accounting industry will be held online this year.

This event aims to share the evolving roles and ideal forms expected of accounting firms in the context of changes in the corporate environment and to communicate steps for moving forward. How will "future-oriented accounting firms" demonstrate value on the ground as entities supporting business owners' decision-making? We will explore how accounting firms can think about the future with their clients, sharing specific case studies and mechanisms for supporting business owners' decision-making and guiding SMEs towards the future.
