At our co-op there is rarely a lack of nice Nishiki bikes coming as as donations and we have seen an inordinate amount of 25 inch road frames of late... most of these have required little work and their finishes have held up beautifully. These are just about all Kawamura models although we also got a nice 5 speed Nishiki townie that is of Taiwanese origin.
My Nishiki looked exactly like this and cost $900.00 Cdn in 1983... our exchange was very poor but the bike was worth every penny.
