Takafuku Haneda Airport International Terminal

A friend recommended this place for sukiyaki. It’s outside of the security gate, so timing can be a little tricky, but we had a long layover. This place actually had no line — I’m guessing due to the prices.
For what we got, we thought the prices were very reasonable. We did one High Quality Sukiyaki set (they also have lean and marbled beef, which are lower grade and less expensive). We added some vegetables and shirataki noodles (in addition to the ones that came with the set). It ended up being enough for 2 people. The set also had rice, miso soup, and pickled vegetables.
They start the pot off with some beef fat and then you can start cooking whatever you want. The 3 slices of beef were nicely marbled, cooked quickly, and basically melt in your mouth. After it’s cooked, dip it in the raw egg, and it’s pretty amazing. As for vegetables, we had shiitakes, other special mushrooms, tofu, carrots, napa cabbage, and some other greens.
They also had Yamazaki at around Y1100 for a double sized pour.
They were very efficient and kept coming by to refill water and help us maintain the sukiyaki (we kept forgetting to add more kombu or soy sauce). This was definitely good for airport food, and they take credit card.
