I think this is my favorite chapter so far.

We find ourselves in Kawagoe this chapter, which lies roughly 50 miles (80 km) north of the Miura peninsula, as the crow flies (in our world). Multiply those figures by ten and the trip becomes quite long; the Cub has a quoted range of 460 miles and a cruise speed of 115 mph.
There's a bit of a pun in the noodle shop's name: Isa Soba. Thanks go to a Japanese blog that pointed out how there's a lake in Kawagoe called Lake Isa. "Soba" can mean "buckwheat noodles" but it's also a homonym for "next to."
A lot of food gets mentioned in this chapter: eggplant tempura, squid tempura, soba zenzai, awamori, sata andagi, soba karinto. Damn, I get hungry just thinking about it.
