We saw probably the most amazing show on the planet at the Robot Restuarant (I won't spoil it for you.), ate at vending machine restuarants, slept in 5 star hotels and in cool tiny manga cafes. We got kimonos for pajamas, song karaoke where we made a couple of Japanese friends, shopped at the 100 yen shop, rode the most fun metro system around and saw the Tokyo Tower. We had the most amazing time of our lives for free!
Next, estimate your monthly spending habits for other expenses such as gas, groceries and entertainment. Create a limit, based on your income, of what you can spend in each of the different categories of expenses. For example, if you tend to spend $400 a month on groceries, try to stick to $300 a month on groceries by making changes like buying generic brands, using coupons, and resisting impulse purchases.
