Thank you, Greg in the Phillipines!
I finally managed to get some kerosene, which I have found out, is pronounced touyu in Japanese. An 18 Liter blue plastic container set me back 840 Yen and 18 Liters of touyu set me back 1,134 Yen.
$20 is a small price to pay for warm toes and a happy girlfriend.
But that's not all!
When I tried to vacuum today I found that the bag hadn't been changed in about 10 years. Gross. I went to SATY in the hopes of finding replacement bags at a reasonable price. There were four different types of bags to choose from and I had to figure out which one I needed by reading the hieroglyphics, I mean kanji, on the package. I may have mentioned before that I am a functional illiterate here in Japan. That's not true. I am just plain illiterate.
I picked the package that had a picture of a vacuum cleaner that vaguely resembled mine on it. When I got home and tried putting it in, it fit! Super Excellent Joyousness!
I also bought Emily a pink umbrella.
What a great afternoon!
