HATED the Thai rice. I had never eaten rice but once in my life before coming to Japan (airline meal) and until I tried Thai rice had been of the opinion that rice was to food as water was to drink....something totally without any flavor of its own. I never appreciated how good Japanese rice tastes until I tried that awful Thai rice.
Once supplies of domestic rice stabilized again there were rice dealers in Japan who found themselves stuck with a now unwanted stock of leftover Thai rice, which they quite literally couldn't
give away. The rice shop in my neighborhood was offering bags of Thai rice
free as a "present" to people buying Japanese rice....and the customers refused it and left it in the store.
