Hi,
We are analyzing the feasibility of using Splunk tool in a Japanese environment.
Does this tool have the development environment in Japanese.
Also please provide the prerequisites to use Splunk in Japanese system
Yes, you can use Splunk on Japanese environment with translated GUI + Japanese Encoding for input data.
For prerequisites for installation, you may refer to the installation manual, and I don't think there is specific environment requirement for Japanese environment.

Also documentation is available in Japanese.

To view Splunk UI in Japanese, change locale portion (e.g. en-US) SplunkWeb URL to ja-JP
