Managing director
I see e-commerce as a system and your shop as part of it
I am Ryusei Hosono, Japanese, grew up in Düsseldorf and now managing director in Tokyo. I was the starting point of HosonoDE and still shape the agency's direction, but the most important factor is our team: almost 20 people bringing together e-commerce, development, marketing, operations and AI.
Years in web & e-commerce
Since 2016 I have built structured professional experience in web and e-commerce. Before that I already worked on my own web projects; today we solve complex shop and marketing topics for you.
Regional focus
I know the German-speaking market from daily work. That is why HosonoDE is clearly focused on DACH clients for you, even though we are based in Tokyo.
Strategic direction
With IRIS, HosonoAI and automation I use AI to make our workflows and yours leaner: fewer manual steps, clearer processes, so over time you pay less for the same output and we can work together in a more cost-efficient, focused way.
Perspective
What my path means for you
From 2016 to 2018 I worked at an agency with more than 300 people and started my apprenticeship as a media designer for digital and print in parallel. From 2018 to 2020 I was an e-commerce manager in Hesse for a footwear brand. Right where you often sit: shop operations, product data, campaigns, KPIs. Since 2020 I first worked as a freelancer and then built HosonoDE from that demand. That is why I understand your side of the table as well as the big-agency setup.
When I moved to Japan, I deliberately started as a freelancer. The agency was not a show piece, but the logical answer to more demand, more complex topics and the insight that real quality pays off especially when specialists work together. That is why HosonoDE is no longer built around one person, but around a close-knit team.
Today I think in years for you, not only in tickets. A short-term fix can help. The real leverage is stable shops, clean data, clear processes and sensible AI. This is what we work on together: not just patching once, but measurably strengthening your e-commerce system as a team.
Not me alone: the team behind HosonoDE
As managing director I provide direction and accountability. The day-to-day quality comes from our team of almost 20 people connecting development, e-commerce, marketing, operations and AI.

2016 to 2018
Agency with more than 300 people: pace, processes, large teams, alongside the start of my apprenticeship as a media designer for digital and print.
2018 to 2020
E-commerce manager in Hesse for a footwear brand: day-to-day shop work, product data, campaigns, the view from your side of the table.
2020 to today
First freelancer, then HosonoDE: growing demand became a clear offer for German-speaking SMEs, with a team in Tokyo and Europe.
HosonoDE has grown but stayed personal: when you work with us, you still feel my standards for clarity, quality and long-term partnership, just no longer from me alone.
