Regarding visa

i have been rejected japan visiting visa one of my japan friend send me invitation to visit japan and i applied but they denied my visa even i didnt get any reason for that its 9 months ago my question is that should i apply again for japan visa to get once again invitation from my friend ?

You can try but no one can guarantee the approval/success.

Rejection can be of many reasons, mostly due financial reason or discrepancies in your application form and submitted documents.

Normally if application is rejected, you'll need to wait at least 6 months before applying again for the same visa.

Your name seems Indian. Now a days its difficult to invite friend from India even though japanese sponsor you unless you have a sound base. If Indian living in japan sponsors Indian relative, it may work out.
