Logistics
Housing
Hotels are generally cheaper than airbnb. Space tends to disappear than in other locales, so book ahead to save money and have more options available.
Food
Food is generally very cheap.
Fast food
Ramen, conveyor belt sushi, and chain restaurants like MOS Burger, Yakiniku Like, McDonald's, and KFC are your best bet for obtaining food cheaply (1000¥ or less) and quickly.
Lunch
Many fancy restaurants that typically charge 10,000-20,000¥ charge merely 1000-4000¥ during lunch due to lower demand.
