Location requirement: you must already be living in Japan with valid work authorization. We are not sponsoring relocation or visa transfers from overseas for this role. Applications from outside Japan will not be considered.

CONTEXT
A major Japanese industrial group is building an in-house DX & Data Science team. Two data scientists are already on board; this senior hire completes the founding core of the team.
This is not a pure research position. You will work directly with business leaders and operational teams to solve real-world problems across the group: sales and marketing, customer experience, supply chain, manufacturing excellence, business process transformation and corporate functions.

WHAT SETS A CANDIDATE APART
• Experience in manufacturing, industrial automation or B2B industries.
• Experience with SAP, CRM or enterprise operational data.
• Experience leading global, cross-cultural projects.
• Generative AI and large language models.
• PhD in a quantitative discipline.
• Prior experience inside a Japanese company or Japanese business environment.

WHAT “SENIOR” MEANS HERE
The client's own definition, as written: ability to independently lead end-to-end projects; ability to influence business decisions through data; ability to communicate effectively with executive leadership; ability to mentor junior team members; a proven track record of delivering measurable business impact.

WHAT SUCCESS LOOKS LIKE IN 12 MONTHS
• Deliver at least one high-impact business analytics initiative.
• Establish strong relationships with key business stakeholders.
• Contribute to the organisation's data-driven decision-making culture.
• Act as a trusted advisor to business leaders on analytics and AI opportunities.

LOGISTICS
Location: Japan — Tokyo or Kyoto, on-site / hybrid. Start: as soon as a selected profile is approved. Engagement: freelance or permanent in Japan via Abbeal KK — both are open, to be confirmed at first call.

YOUR PROFILE
• Python, SQL, machine learning frameworks, statistical analysis and data visualisation tools — Power BI preferred.
• Proven experience deploying machine learning models in production environments.
• Experience working with large enterprise datasets.
• Experience with Microsoft O365 and Copilot.
• Strong stakeholder management: turning business problems into analytical solutions, working with senior leaders and cross-functional teams.
• Genuine autonomy, with limited supervision.
• Comfortable inside a traditional Japanese organisation: implicit decisions, nemawashi, scope that firms up gradually.

MISSION
• Lead advanced analytics and machine learning projects end to end — from business problem definition through production deployment.
• Build predictive models and decision-support solutions using structured and unstructured data.
• Work with business stakeholders to identify opportunities for AI and data-driven improvement.
• Translate complex analytical findings into actionable business recommendations.
• Support strategic initiatives across sales and marketing, customer experience, supply chain management, manufacturing excellence and business process transformation.
• Coach and mentor junior data scientists and citizen data analysts.

ELIGIBILITY — READ THIS BEFORE APPLYING
The client has now issued its written job description. It sets blocking requirements: an application that does not meet them will not be reviewed, however strong the technical profile.
• Business-level Japanese, demonstrated: JLPT N1 or an equivalent certification is expected. Proficiency must be shown through formal certification and/or professional experience genuinely conducted in Japanese. Self-declared conversational Japanese does not clear the bar — meetings and workshops are held in Japanese.
• Tokyo or Kyoto, on-site or hybrid: the role is based in Tokyo or in Kyoto — the client confirmed both sites on 2 September. It is not fully remote, and it is not in Osaka. Employment conditions differ between the Kyoto headquarters and the Tokyo Shinagawa site; we raise this at the first call.
• An already-settled long-term life in Japan: permanent residency, spouse visa, long-term work visa or Japanese nationality. Working Holiday, recent arrival and relocation from overseas are out of scope. No visa sponsorship.
• Master's degree or higher in a quantitative field (Data Science, Statistics, Mathematics, Computer Science, Engineering). PhD welcome.
• Minimum 5 years of hands-on experience in data science, machine learning or advanced analytics.
