The previous day had been wonderful; breakfast for 325 yen at Mugimaru and a visit to the East Gardens of the Imperial Palace, lunch at Otakou Honten and a couple of beers at the Hitachino Brewing Lab, and then dinner with our good friend Reiko at Suzunari. So what would we do next? Well, the Missus decided that She hadn't had enough of Kamakura and wanted to return. So we woke rather early and walked down the street to Tokyo Station. We entered into the Tokyo Station underground…"B1" thru the Yaesu exit/entrance and came across this place.
Curious, I walked over. There was a ticket machine and it looked like they served Japanese breakfast. If you've read our blog long enough; you know that I hold a special place in my heart for Japanese breakfast. And while in Sapporo, the Missus developed a fondness forthis as well. So, it was off to the ticket machine.
The Missus beat me to the Natto Combination….so I got the Nikudōfu (simmered beef and tofu) combo. Both were an inexpensive 570 yen! The seating was interesting; salarymen were seated together, sometimes sharing tables. But because I was with the Missus we were seated in a booth.
The Server took our tickets and soon enough our food arrived.
Think of this the next time you grab something from Mickey D's or the like for breakfast. For about $5.50, the Missus got tofu, natto, and even some sashimi with Her combo. Which, BTW, She really enjoyed.
What I got wasn't exactly slim pickins' either.
The beef and tofu; while not amazing were both nicely flavored; not too salty, not too sweet. When did I start enjoying mentaiko for breakfast? I'm not sure, but I really like the saltiness…and perfectly cooked rice.
Don't need much more than that.
Hatsufuji was an interesting place. We passed by several times during our stay. After breakfast, the ticket machine is rolled to the side and you'll notice a collection of set lunches, displayed in full plastic glory in the window. 
During the evening, the place becomes an Izakaya. I find it fascinating and I'm hoping we'll be back in Japan more sooner than later. And if we're around the Yaesu exit of Tokyo Station Underground you can be sure we'll be back at Hatsufuji.
