About Koji

Fort de plus de 5 ans d’expérience au Japon dans l’industrie des technologies, de l’électronique et des systèmes électriques – notamment dans le secteur automobile – j’accompagne aujourd’hui des entreprises dans la réflexion et la mise en œuvre de stratégies commerciales internationales.

Je travaille actuellement pour un acteur majeur de la connectique, où je mène des négociations techniques et commerciales de haut niveau, en interaction avec des partenaires et clients du monde entier.

Ma valeur ajoutée repose sur :

✔️ Une triple compétence linguistique (français, anglais, japonais – courant)
✔️ Une fine compréhension des environnements multiculturels et industriels
✔️ Une capacité à traduire des enjeux techniques en leviers business, dans un cadre B2B exigeant

Que ce soit pour définir une stratégie, structurer un discours commercial international, négocier avec des partenaires étrangers, ou simplement mieux aligner vos équipes internationales, je peux vous accompagner avec rigueur, adaptabilité et impact.
