Guest Houses in Chiba

Unfortunately there are not a lot of guest houses in Chiba Prefecture. However, through my own research I have found that there are some guest houses and most of those guest houses are in Funabashi. Here are some of the well known guest houses in Chiba Precture (not only Funabashi)

Room Share

Room Share has several listings for guesthouses in Funabashi city from 40-000 yen to 60,000 yen. Foreigners are always welcome and fees are very low. The only problem is that there website is almost completely in Japanese. If you can navigate through the website you should have no problem finding a nice cheap guest house in chiba.
