How to spend exactly $2k in Japan for two weeks

I went to Japan at the end of January to the start of February for two weeks, and I spent exactly $2k from plane tickets to every meal I ate, heres how:

Technically I spent more than that, because i asked my parents to pay for the flight ticket. Because I went to Hong Kong for the following two weeks and they were willing to pay for the ticket. So step 1, have great parents like mine and be grateful.

Step 2 is to plan where you want to go and have a great friend who has the same budget. Trust me you'll enjoy it so much more than to travel with someone who you don't enjoy their company as much. Very fortunately I travelled with my best friend, and we've promised each other this trip for three years now. It was cheap travel, but it was a great trip. 

We did not plan where to go. We only booked our accomodation two days before we arrived Tokyo. And we only know that we are landing and departing in Tokyo. We also bought a JR pass so we can travel unlimited seven days by the JR train and bullet trains. 

We stayed in capsule hotels for the entire trip. It was cheap and usually in extremely convenient locations for roughly $25-30 a night. Capsule hotels are a Japan-exclusive experience, the traditionality of the capsule hotel culture only remains in Japanese capsule hotels, though capsule hotels exist in other countries, its just not the original. 

We also budget our meals to be roughly $12-$15 per meal. Japanese food is not cheap. You get a portion that fills you half way with that budget. But they are the most flavourful Japanese food you'll eat, other replicas in other countries just doesn't have the flavour. 

The rest that I spent on was Japanese skincare and entertainment in arcades and snacks and peculiar things that is only available in Japan, like the toy in the picture, it's literally just a toy that sits at the rim of your cup, there's nothing else to it. 

On my last day I had 2 yen left.
