When the economy was good and everyone was enjoying life with nary a worry, you might see one posting a day from Craigslist, usually from someone who was going to upgrade his Ikea bed to something sturdier. Or one of the English teachers moving to a new prefecture and not planning to move everything with him.
I like the fact that the foreign, and especially Japanese, community are very conscious of the environment. Recycling is big, every household is expected to separate their garbage and encouraged to be eco-friendly. 2nd hand shops take in unwanted but usable stuff, clean/fix them up, then sell to those who are interested.
Book Off's for good bargains. Knowing the Japanese, they take the effort to clean and ensure that what you purchase is still in good condition. A lot of the furniture and electrical items that I had were mostly hand-me-down's and second-hand goods. Like the table above was bought at a steal at only JPY50, and the heater below at no more than JPY500.
It's definitely much fun when living in a student community because the items go around easily. The winter warmers I inherited from a Filipino student were donated to the church for their charity bazaar, the kitchen cabinet and table my Malaysian senpai sent me were given to incoming Indonesian students, the trusty bicycle that brought me around Niigata was passed on to Gene, who had not cycled in his life before.
