Even the best products fail to be chosen unless their meaning is translated and presented with care.
Walnut reads the essence carried by makers and regions, then designs how their story is told, shown, and sold — through to real revenue. We bring modern tools (generative AI, social media, digital advertising) to bear with discipline, implementing on the ground until results appear in the numbers.
Services
01 and 02 focus on individual products and businesses; 03 takes an entire region as its scope.
Across all three, we edit value for its context and implement the structures that turn it into revenue.
Individual Product / Business
01
As the Japanese distributor for overseas products not yet available in Japan, we handle the end-to-end pipeline — from distribution contract negotiation, localization, and channel design, through crowdfunding launches, to e-commerce growth across major Japanese platforms.
For Overseas Manufacturers →Individual Product / Business
02
For local Japanese producers who make great products but struggle to sell, we partner on-site to read their strengths and implement branding, e-commerce, advertising, and sales as one unbroken sales engine — until results show up in revenue.
Regional Scope
03
Drawing on experience in public service and DMO operations, we partner with municipalities, chambers of commerce, regional financial institutions, and businesses to re-edit dormant regional value and turn it into structures that return as revenue.

About
Walnut LLC was founded in October 2023 with the mission "Building markets for things that matter."
We operate three services — overseas product distribution into Japan, sales growth support for domestic regional producers, and public-private regional value editing. The scopes differ (a single product, a single business, an entire region), but the essence is shared: implementing the structures through which genuinely valuable things reach the right markets.
The name "Walnut" refers to the nut tree symbolizing wisdom, integrity, and steadfastness across classical traditions. We embrace these principles — learning from classical wisdom, delivering value with sincerity, and building things that endure.
Representative
Representative Partner
Nine years at the Tochigi Prefectural Government — including a two-year secondment to Ashikaga Bank — gave Fujinuma a foothold in both administrative and commercial frontlines. After independence, he ran one of Japan's top public-service blogs (around 6M PV/year), then served as COO of a regional DMO before founding Walnut LLC in 2023.
His core strength is "editorial capacity" — distilling what the counterpart truly needs and transforming raw material into measurable outcomes across public, private, and entrepreneurial contexts.
