After just a night in Tokyo (we'll be back later), we are headed up to Kinosaki Onsen Town for the next couple of days. It's a pretty long train ride (almost 5 hours with transfers) so getting ekiben was required. Ekibenya Matsuri in Tokyo Station is a crazy place that has a huge selection. We always try to get something different each time, including ones with collectible containers for my daughter.
I opted for the unagi bento which was quite good (though would have been even better served hot). My wife is a huge squid fan and these stuffed squids (ikameshi) are a regional speciality of Hokkaido. Riding the Shinkansen just wouldn't be the same without ekiben!
