Estonia · European Union
MKSJ OÜ is an Estonian company that develops mobile applications and brings carefully selected Japanese products to customers across the European Union.
MKSJ OÜ is a private limited company registered in Tallinn, Estonia.
We are a small, hands-on team. Our work combines two things we know well: building focused software for mobile devices, and operating online retail across borders.
Our founder has run cross-border e-commerce from Japan for more than 14 years, serving customers in over 50 countries. MKSJ OÜ brings that experience to an EU-based company, so that European customers have a responsible, reachable business inside the Union.
Two lines of business, one set of standards: clear information, careful handling of data, and a real person to contact.
We design, build and publish our own applications for iOS and Android.
We sell Japanese products and digital goods online to customers in the European Union.
Information under the EU General Product Safety Regulation (Regulation (EU) 2023/988, “GPSR”).
If you believe a product you bought from us may be unsafe, please contact us right away.
Registered in the Estonian Business Register (e-Äriregister).
