Japan is expensive. They do not exaggerate when they say that. It really is. But that’s not to say it’s not a good place to travel in. Japan is incredibly tourist friendly despite the language barrier, and a lot of tourist attractions have free admission (well, mostly temples, shrines and palace grounds).
Now that more budget carriers are flying direct to Japan from Manila (including Jetstar), it’s cheaper than ever to go there. The biggest expenses in Japan are the transportation, accommodation and food. A ride in the subway costs a minimum of ¥200 (around Php 100), same with buses. But if you don’t mind walking, you can make most of Japan Rail’s network to get around for free if you’re holding a Japan Rail Pass. Accommodation costs can be driven down by staying in hostel dorms or even further down by Couchsurfing with a local host. As for the food, Japanese supermarkets and convenience stores offer bento boxes of real food, so you won’t have to live on instant ramen (unless you’re really strapped for cash). Onigiri (rice ball with filling or seasoning) starts at ¥68, bento at ¥350, depending on where you’re buying.
