In order to check the figures in my post of the other day, I took a detour to the rice section of my local supermarket. I found that I had been too generous in my quoted figures. Uonuma Koshi Hikari, the most prized rice, was 3480 yen for the 5 kilo bag, not 3850 as I had remembered it. As for the low price substitute, the supermarket had 5 kilo bags of Koshi Hikari from other parts of Niigata Prefecture, the prefecture reputed to grow the best rice, for 2180 yen, well below the 2850 figure I quoted for what are less popular strains of rice from less-well-regarded growing areas.
All this fact-checking was possibly for naught, however. The comments section of my earlier post offers a revelation of spicy duplicity, which, upon reflection, is an obvious bit of cheatin' in order to stick it to the The Man Back At HQ.
