Hi guys!
I've to offer to my boss a dinner in Tokyo, any idea where I can bring him? Should be a good one and with Japan-style dinner!
Thanks a lot

With more Michelin-starred restaurants than any other city on earth, you shouldn't have a problem finding one that fits your needs. A few questions:
* How much are you willing to pay?
* Where are you staying? (I assume your boss isn't a native.)
* "Japanese-style" includes many things from homestyle food to hotpots, from sushi to curry and more. What's Japanese-style in your mind, or are you open to any type?
* How much lead time do you have to make a reservation?
* What kind of atmosphere are you looking for?

Thanks for your reply
Unfortunately we will stay in hotel near airport NRT due to a conference there, but we may travel near the city if it worth.
Maybe a sushi or sashimi restaurant?
Price...herr...about 100 bucks per person? Or is too less?

Since you are staying quite a distance from cental Tokyo- I think eating at your hotels best restaurant is your best bet.

I am by no means an expert, but if your budget is $100 per person, I suspect you may be better off just going someplace near your hotel. I had a couple forgettable sushi meals in Tokyo, but the memorable one cost about $350 per person for lunch. (That was at Kanesaka, which has one or two Michelin stars.)

Inexpensive food can be found in Tokyo--and it's great--but it seems to be most common at quick-service restaurants (ramen, curry, katsu places, etc.). But there's a lot of fantastic but insanely expensive food, too, and even mediocre places can be expensive by non-Japanese standards.

Yes, that is too less.

You are asking about spending no more than 7,500yen on an evening meal.
If you were to go by train from Narita to Tokyo, this would be at least 2,000yen each for the return trip.

If you could take out your boss for LUNCH rather than the evening meal there are a whole assortment of world class restaurants where that money could buy you a truly memorable multi course menu. At dinner time... not so much.

From what you've requested here, a near $100 evening Japanese meal where you want to impress your boss, best use of time and money might be the 8,400yen 雅 （みやび pronounced miyabi）option on the dinner menu at
Kyouryouri Hanamura (which means Village of Flowers - Kyoto style cuisine)

It's just a little outside of Narita town. Copy and paste the next line into Googlemaps for a visitor friendly map:
千葉県成田市東町85-16 　

Here's the blog entry detailing a visit to this restaurant. The writer/photographer chose the 8,400yen miyabi option on the menu. So this is exactly what you'd get for your just over $100 x 2 investment.

There's a large modern Japanese-style restaurant that I've eaten at on the east side of Chiba station that would be in that price range and provide an interesting experience. The menu has pictures next to all the items so you have a guide to figuring out what you are ordering.

I can spot the building on Google maps (it's in 33-cho) if I enlarge the map enough but I can't figure out how to give precise directions although you can't miss it if you get nearby, it is a modern Japanese-style building with a blue roof and banners outside. This is the quiet side of Chiba station, not the one most exits dump you at.

Chiba station is a 30 minute and Y480 ride from Narita town on JR. If you're up for a bit of an adventure, this might be fun. Also the main side of Chiba station has a lot of little shops to look at.

I wouldn't bother leaving Narita. You could get decent sushi within your price range:
