What’s ahead in Japan?

Obesity in Japan is often overlooked. Although the country is seen as a “slim nation,” the WHO recognises obesity for Asian populations from a BMI of 25 due to higher health risks at lower thresholds. Around 20% of adults receive obesity indicators during annual check-ups, yet many don’t get access to ongoing, supportive care.

Euc is here to offer a more supportive path through:

• Thoughtful, evidence-based clinical care
• Ethical and responsible prescribing
• Accessible, affordable treatment options
• Warm, non-judgmental support for every patient

Our aim: Help people in Japan live with confidence, vitality, and long-lasting wellbeing.

• Grow with us globally - Get mentorship from leaders across Australia, the UK, Germany, and Japan while collaborating with top-tier teams in the Philippines and South Africa.
• Shape your career - Access learning budgets (includes language learning), shadow peers in other teams, and learn from a global knowledge-sharing culture.
• Work where wellbeing matters — Enjoy wellness budgets, mental health support through our Employee Assistance Program, annual health checks, flu shots, and work from anywhere policy,
• Innovate with purpose - Work with state-of-the-art tools and contribute to bold, impactful solutions in healthcare.

At Eucalyptus, we value individuals from all backgrounds, experiences, and perspectives, and we embrace the unique qualities each person brings. When you apply, please let us know of any reasonable adjustments you may need during the interview process.
