Fixed costs: Office rent — You must get used to having a smaller space to move around in than some of the cavernous office spaces that (successful) SFO startups enjoy. But all in all value for money is roughly similar to other big cities. As a guide, we pay about US$3,000/month for a 700sq ft office w/kitchen/bathroom etc.
Travel etc except for cabs is cheaper I think.
Food is, hmm. Well you can eat for really cheap, or you can blow all your dough on one meal. Up to you.
Utilities etc — probably the same as anywhere else.
Hosting, accounting, whatever — As you might have seen (http://hackerne.ws/item?id=2115203) we use a whole bunch of US services for this stuff. We pay about $400/month for our accountant.
Lunch is usually pretty cheap, dinners are expensive. Also, drinks are very expensive! I drink a lot of water because I refuse to pay ¥600 for my meal and then ¥650 for an iced tea.
For startups, I highly recommend living out of the combini. I would never eat in an American 7-Eleven but here, you can feast.
Foreigners typically get compensated better unless they're stupid. sheepishly raises hand
Two issues in hiring that are relevant for startups: bilingual engineers are as rare as hen's teeth, and the traditional expectations of Japanese society strongly counsel your best potential hires to ensconse themselves in a secure job at a Japanese megacorp rather than rolling the dice on a startup.
Most relevantly to the "how" question, single Japanese thirty year olds on average consume much less housing than most HNers would tolerate. Many, particularly unmarried women, live with their folks. Others might be in e.g. a one-room rokujo (six tatami mats in area) apartment costing $600 a month, which would not be atypical in Nagoya.
Three million yen is sufficient for a comfortably middle class life for a single man in my town. Trust me.
You should come to the hacker news meetup in February! I'm sure there are a lot of people who would love to meet you guys!
