Langfuse Cloud Japan

Clemens Rawert

A new dedicated cloud region in Tokyo keeps traces, prompts, and evaluation data inside Japan.

Langfuse Cloud is now live in a dedicated Japan region, hosted in Tokyo (ap-northeast-1). Traces, prompts, and evaluation data stay in Japan. Langfuse Cloud Japan is available via https://jp.cloud.langfuse.com - you can sign up now.

What is Langfuse Cloud Japan?

• Full platform parity with Cloud EU and Cloud US — same features, same API surface, same SDK support
• Data stays in Japan — traces, prompts, and evaluation records are stored and processed in Tokyo
• Japanese-speaking team based in Tokyo for sales and support
• Migration path from Cloud EU or Cloud US — data migration script. You can reach out to us if you have a very large amount of trace data to migrate (>2M observations)
