It seems the idea is that she's making her way around Japan, blogging as she goes.
In order to make it TV-worthy, they do a thing where the money she has available is decided by dice roll and blog comments.
If she rolls a 1, she loses all her cash, and has to hitch-hike to the next goal. Otherwise she gets money based on the number of comments on her last blog times 0.1 for a 2 or 3, 1 for 4 or 5, or 10 for 6.
She rolled 6 last week, so she got like 80,000yen and was cashed up this week.
