About udon noodle soup

A plain bowl of udon is mostly thick wheat noodles in a light dashi-and-soy broth, so it lands lower than most noodle soups. Tempura, fried tofu, beef or curry toppings are what lift it toward 600. Built from its parts: a standard kake udon bowl of 250 g boiled noodles in a dashi broth seasoned with soup base, valued with Japan MEXT figures.

What moves the number

Why one plate is 250 and another 650

  • Drinking the sweet soy broth

Ordering lighter

If you want a lighter plate

  • Choose a plain or wakame bowl
  • Add an egg or vegetables instead of tempura
  • Leave some of the broth

Off unless you turn them on

Calories in PlateDiary are off unless you turn them on. Switch them on and, when PlateDiary AI reads your photo of the table, each dish gets one rough “~” number. Accept it or change it; a number you correct is remembered for that dish. With Calories off, the app looks exactly as it did before.

A read sends small pictures of the cut-out dishes, with the place's name as a hint — never the table photo, faces or your location. Calorie numbers never go to analytics, and nothing is written to a health app. PlateDiary AI starts with free tries; here is how it works.
