Hello guys, I'm planning for a trip to Japan

Just want to ask, will RM5k of expenses be a bit of a stretch for a 2 weeks trip? Or it's safe to up the budget a bit.

I've not decided where or when to go yet, but I'm planning to go do some sight seeing, taking photographs and such. Living and eating won't be a major concern, so I'll be okay with staying in budget hotels and such.

Oh and I'm planning for a solo trip.
