It looks like you're sharing a ham radio QSO (query and response) log entry!

Here's what I can decipher from the text:

* `07:08` is the time of the QSO.

* `7M3DUU/P` is the call sign of the station being operated by... well, someone! The `/P` at the end indicates that it's a portable operation (as opposed to a fixed location).

* `on JP-1177(Arakawa Oaso Prefectural Park, JP-ST)` tells us where this portable station was operating from. This is likely a grid square reference, and Arakawa Oaso Prefectural Park appears to be the location.

* `24915.0 FT8` indicates that this QSO occurred on the FT8 digital mode, using the frequency 24.915 MHz (which is a common band for amateur radio operations).

Do you have any specific questions about ham radio or would you like me to help with something else?
