= Components =

 * Transport: $1100
 * Accommodation: $332
 * Food: $275
 * Communication: $60
 * Entertainment: $60
 * Goods: ???
 * Shipping stuff home: $80

Total: $2307 plus whatever we spend on goods.


= Transport =

 * Airfares estimated to be $1200
 * JR pass should be $300
 * Non-JR travel will cost extra, but probably not much, assume 3000 yen for time not covered by JR pass.

Call it '''$1500''' for now.


= Accommodation =

 * Nagoya: 1 night = 7000yen for 2 people (about 76AUD)
 * Osaka: 1 night = $56 for 2 people
 * Airbnb accommodation in Naka-Meguro will be about $200

Estimate '''$332'''


= Food =

Guessing $25 per day.

Estimate '''$275''' after adding some fudge factor.


= Communication =

Phone rental and data SIM purchase?

Maybe '''$60''' depending on how we do it.


= Entertainment =

Mostly arcade games and anything to kill time.

Estimate '''$60'''

= Goods =

 * Otaku goods
 * Cosplay goods
 * Souvenirs and stuff that people requested
 * Some may be repaid later

Impossible to estimate, assume hundreds of dollars :D


= Shipping stuff home =

Call it '''$80''' for now, may not be necessary at all.
