I have no idea how or what to eat!?

Restaurants give you menu to order but all are written in Japanese.
Some restaurants have menu with colored pictures for your betterrecognitionn.

Even at McDonald's, you have to speak in Japanese to order.

Japanese use chopsticks instead of Knife and fork.

Try some Izakaya-type restaurant where are so many small dishes you can try in all together like as below.

You don't give any tips to waiter/waitress.

This is a very exciting thing for you but kinda scary to.
I have been to a few countries, and the local people are very help full and love to share there culture.
You could find a friend over there, just a person who says hello to you, ask them to show you around.
Never be afraid to ask questions, and just have fun.
The japanese people are some of the nicest people out there and they are proud of there culture.
And a lot of them will be able to speak english well enough for you to order food.
You will most likely run into other americans while there and they can help you out as well.
I am jealous!!! have a great time!!!

Try everything! Go to an all you can eat buffet and get very small portions of everything!

There are a lot of varieties, but for your sake, ill pump out a few classics and the proper etiquette for them.

Well start with Chopstick etiquette. A few things to remember, dont ever use them as drum sticks or violently rub the chopsticks together, if you do, don't be surprised if someone yells at you. Always try to keep your chopstick clean, and when your not using it never leave it sticking in something (IE sticking it in your bowl of rice). Leave your chopsticks laying down on something, on top of your bowl is OK.

Ramen, Udon, Soba- Noodle type dishes- Ramen are made from eggs, Udon from Wheat flour, and Soba from buckwheat. Each of these have a different way of being served, just grab whatever looks good.
Etiquette: Basically you want to eat the noodles and sip a little bit of soup at the same time, so basically you want to pick the noodles up with your chopstick and slurp it in. Yes, that does mean make noise, but don't make TOO much noise to annoy people, but dont be too quiet.

Japanese Curry- You usually get to choose your desired spicyness. As far as Etiquette goes, just eat it lol. Whether you mix it up or keep eat it as is, is up to you.

Tonkatsu- Pork Cutlets that are breaded and deep fried, very delicious! Usually comes with Miso and rice.
Etiquette: For any dish that comes with miso and rice, ALWAYS start with the miso soup. Then go ahead and eat whatever.

Sushi- My favorite, the big trend these days are the Kaiten-zushi which is basically sushi on a conveyor belt. Its cheap and if you hit a good place its absolutely delish. The main difference in japanese Sushi and US sushi is that the japanese don't really make rolls at all, and Wasabi is only included inside the sushi and doesnt come extra on your plate.
Etiquette: Don't pour too much soy sauce in your plate. When you dip the sushi in the soy sauce make sure you dip it so the soy sauce gets on the fish, not the rice. The most important thing about sushi is to eat it WHOLE! Yes, cram that in your mouth and enjoy it.

These are classic dishes in japan. The rest is up to you, try things and explore. But most of all enjoy it! Best of luck!

Many Japanese restaurants either have photo-menu or a case-display outside the restaurant. The first time I went to Japan, I didn't speak any Japanese, so most of the time, I just bring the server to the display case and pointed at the dish I want. Because you're going to Tokyo and Kyoto where they are used to seeing tourists, they'll understand and many people will love to help you out if you're stuck language-wise.

Things you would want to try - udon or any type of noodle house, and robata (grill). There are tons of noodle houses around Ginza (Tokyo) area and tons of grill places in Shinjuku (Tokyo).

Another place you can try is the food market at the bottom level of most larger department stores.

Customs? Etiquette? Don't stick your chopsticks into your bowl (ie. chopsticks standing up straight in a bowl of rice).

I recommend that you use your greasy fingers to eat everything, shout out lots of inappropriate profanity, and smear chocolate puddding all over your mouth so as to set a good example of how progressive we Western Barbarians really are...

in the course of the day, in the adventure that your body is going 5 hours without nutrients it is going to move into starvation mode, that is why everybody says to eat each and every 2-3 hours to save your metabolism going and its maximum ideal. doing what you're doing will in straightforward words promote over ingesting, so no i dont imagine your plan is a robust theory. commerce off your junk nutrients for wholesome nutrients and also you'll reduce weight. high quality and volume are both substantial even as on a nutrients regimen. eat a lot less at evening, and fill your dinner finished of greens, and also you'd be strong, yet dont decrease it out totally. otherwise, perhaps really of ingesting dinner you should graze after 4:00, and oftentimes go back to the kitchen and grab some carrot sticks and grapes and different wholesome snacky meals. only a education. yet no longer ingesting is the worst element to do on your body
