I regret to inform you that I ate no whale, no horse, not even chicken sashimi in Tokyo. I didn’t delve deeply into yakitori esoterica either, though there were opportunities.
Hajimeya I do love Japanese specificity, though, resulting in dozens of subtly different cuts of chicken (hiza nonkotsu/knee cartilage vs. nonkotsu/breast bone cartilage) and pretty much every internal organ up for grabs where we Americans only concern ourselves with thighs, wings, and breasts. Ok, maybe some livers.
The most outré cut I sampled was bonjiri a.k.a. chicken butt, partially because I could say guess what? You know the answer. But also because it provided great contrast: chewy fat, singed skin (shio-style, only salted, for purists) and little crunchy bits of cartilage, all irregularly shaped onto a skewer. Above were also tricky-to-eat wings, skin, and cartilage.
I chose Hajimeya because I was a little intimidated by no English, only paper hand-written Japanese menus on the wall izakayas, and I was meeting a friend of a friend who spoke little English, and I hoped to use him as a translator. But as you can see above, menus were available with English translations scrawled on them.
