About

AltStack.jp is a collaborative project by Alexis Tabary, Olivier Mansion and Kazuo Fukuda. The goal is to highlight Japanese alternatives to major global tech platforms: tools, services, and products made and hosted locally.

Listing Criteria

• The company must be headquartered in Japan.
• The parent or holding company must also be Japanese. Subsidiaries of non-Japanese companies (like the Japanese branch of Amazon or Google) are not eligible.
• Hosting providers must operate on fully Japanese-owned infrastructure. Sub-hosts relying on foreign infrastructure will not be listed.
