Apply →

Working within the Management Strategy Division, you will lead the company’s efforts in translating environmental performance into transparent corporate disclosure. You will be responsible for calculating both negative impacts, such as greenhouse gas emissions from operations, and the positive impact generated by the C2C marketplace’s circular economy model. This role ensures that every metric shared with investors and regulators accurately reflects the company’s dual focus on business growth and resource circulation.

This position matters because Mercari represents a unique case where the business model is inherently tied to sustainability. By quantifying how peer-to-peer trading reduces carbon footprints, you provide the evidence needed to prove that circular consumption is a viable alternative to traditional retail. Your work directly supports the company’s transition toward meeting the rigorous SSBJ disclosure standards, positioning the brand as a leader in Japanese corporate transparency.

This suits someone who possesses a sharp eye for data accuracy and a genuine passion for circular economy dynamics. You should be comfortable navigating complex regulatory landscapes while collaborating across diverse internal teams to tell a compelling, evidence-based sustainability story.

Job FAQs

What are the main missions and responsibilities of this role?

The primary mission involves managing the end-to-end sustainability disclosure process for the Mercari Group. This includes the precise calculation of GHG emissions (Scope 1, 2, and 3) as well as the unique calculation of positive impact—specifically the amount of CO2 emissions avoided through C2C transactions on the platform. You will be responsible for preparing information for impact reports and annual securities reports while coordinating with external auditing institutions to ensure data integrity. Additionally, the role manages responses to ESG rating agencies and direct inquiries from investors regarding the company's environmental and social performance.

Key learning opportunities for this job

Candidates will gain deep expertise in the SSBJ (Sustainability Standards Board of Japan) framework, which is currently shaping the future of corporate reporting in Japan. This is a rare opportunity to be part of a team implementing these standards well ahead of the 2029 mandatory deadline. Beyond compliance, you will learn sophisticated methodologies for quantifying the environmental benefits of circular economy models. This specialized knowledge in 'avoided emissions' or positive impact accounting is a highly sought-after skill set as companies shift from simple footprinting to demonstrating net-positive contributions.

How does the ideal candidate look like (experience, skills)?

The ideal candidate is a data-driven professional with a background in management planning, accounting, or sustainability. You must be comfortable handling large datasets and coordinating with multiple departments to extract and verify information. A mindset that prioritizes problem-solving over rigid adherence to existing methods is essential. Language proficiency is a key requirement; you must be fluent in Japanese (CEFR C1 level) to navigate domestic regulatory documents and internal stakeholder meetings. Professional English skills (B1 or higher) are highly valued for engaging with global ESG frameworks and international investors.

Advice to stand out and make a successful application

To stand out, emphasize your experience with quantitative analysis and cross-functional project management. Mercari values candidates who can demonstrate how they have previously turned raw data into structured, compliant reports or strategic insights. Show a clear understanding of the 'circular economy' and how it differs from traditional ESG reporting. Your application should reflect an alignment with Mercari's core values—Go Bold, All for One, and Be a Pro. Highlighting instances where you took ownership of a complex reporting challenge or improved a data collection process will resonate strongly with the hiring team.

What aspects of the company's sustainability is this role likely to focus on?

This role is heavily focused on the intersection of business operations and environmental impact. Specifically, it centers on 'Value Circulation,' which is Mercari's core sustainability pillar. You will help define how the company’s growth contributes to a society where resources are reused rather than discarded. There is also a significant focus on governance and transparency. By formalizing disclosures, the role ensures the company meets the high expectations of the Prime Market of the Tokyo Stock Exchange, bridging the gap between innovative startup culture and institutional investor requirements.

What are the main challenges someone in this role might face?

A significant challenge will be the evolving regulatory landscape in Japan. As SSBJ standards are finalized, you will need to adapt reporting structures in real-time. This requires high cognitive flexibility and the ability to interpret technical regulatory language into actionable internal tasks. Additionally, quantifying the 'positive impact' of a marketplace is methodologically complex. You may face challenges in establishing defensible calculation models that stand up to rigorous external audit while still effectively communicating the brand's unique sustainability value proposition.

How could a typical day look like for someone in this position?

A typical day might begin with a review of GHG emission data collected from various business units, followed by a meeting with the IR or Finance teams to align on the sustainability section of the securities report. You could spend the afternoon drafting responses to specific ESG rating agency questionnaires. Collaboration is constant; you might touch base with the R4D (Research and Development) team to refine impact calculation logic or meet with the PR department to ensure that sustainability claims are backed by solid evidence. The workflow is a mix of deep analytical work and strategic internal communication.

What are the opportunities for professional growth and development in this role?

This role offers a path toward becoming a strategic lead in ESG management. Because the Sustainability Disclosure team sits within the Management Strategy Division, you are positioned to influence high-level business decisions based on sustainability performance data. Successful performance in this role could lead to leadership positions in Investor Relations, Corporate Strategy, or specialized ESG consultancy roles. As Japanese regulations tighten, professionals with hands-on experience in early SSBJ adoption will be in extremely high demand across the corporate sector.

The main stakeholders you might be interacting with

You will interact extensively with internal management strategy and finance teams to ensure sustainability data is integrated into corporate reporting. You will also collaborate with the R4D, PR, and IR teams to synchronize the company's narrative across different platforms. Externally, your primary contacts will be auditing firms, ESG rating agencies, and institutional investors. Acting as a bridge between the company’s internal operations and the external financial community is a core component of the role’s stakeholder management responsibilities.
