About Us

Our Mission

We want to create a society where everyone can be proud of who they are and where they have come from, regardless of their past experiences. Our hope is to create social cohesion by partnering with local communities to both revitalise the countryside and shift negative perspectives of global workers in Japan.

Social Issue

Skilled global talents continue to be excluded from the entirety of Japan’s workforce despite a shrinking population and strides toward globalisation. 

People from all over the world come to Japan to live and work. In spite of their education and previous work experience, employment opportunities are limited. This is due in part to negative attitudes toward foreign workers, language barriers and precarious legal status.

At the same time, Japan’s rural areas face an uncertain future as depopulation is on the rise.

Our Approach

We harness the language and professional skills of Japan’s diverse population to revitalize rural areas in decline.

Discover Deep Japan fosters a unique environment where we can directly address both the underemployment of talented foreigners and work to revitalise Japan’s countryside areas. Our talented multilingual staff have the language ability, skills and insight to promote Japan’s small towns to an international market. We work and live within local communities and provide tailored digital marketing services to attract foreign tourists and foreign customers for locally produced products.

Culture and Values

– Diversity, Inclusion and Belonging
– Life First, Work Second
– High Performance for High Social Impact
– Autonomy and Accountability
– Candor and Collaboration

Our Impact

About 5

Discover Deep Japan is currently working with ten municipalities and eight local organizations and businesses to revitalise depopulated communities. 

We are committed to recruiting and retaining a diversity of individuals.

Our global workforce is made up of people from all different backgrounds, nationalities, genders, ethnicities and other facets of identity. We actively foster a supportive, strengths-based environment where inclusivity is the norm and everyone has equal opportunities for success. By partnering with local communities we hope to shift negative perceptions of migrant talents and promote further social cohesion in Japan.
