Nagano, naturally ships via Japan Post’s yupack system. We are part of a farmer’s co-operative that gets discount postage but in return has to send from a specified post office. My post office is not open weekends or holidays. I know some are, but mine isn’t. therefore Nagano, naturally orders go out Monday to Friday. I have tracking numbers to trace your packages and if you have a preferred delivery time please just let me know in the comments on your order. I ship via regular delivery (not chilled or frozen) with no problems so far.
As much as possible I ship produce in recycled materials- boxes from the supermarket and newspaper from our recycling stack. I do this to avoid waste and to keep costs down. If you would prefer chilled shipping or new boxes just let me know- the customer is always right!
