TOKYO — A Japanese restaurant is making customized 3D-printed sushi for each of its diners by studying samples of their bodily fluids, reports KXAN.

The Tokyo restaurant, called Sushi Singularity, will ask its customers to send in samples of their saliva, urine, and stools and use them to create 3D-printed sushi tailored to meet their dietary needs.

After clients make a reservation at the restaurant they will receive a health test kit containing vials to collect samples of their feces, urine, and saliva. Once completed, the kit is then sent back to the restaurant for analysis.

Using the data gathered through the samples, the restaurant then creates customized sushi recipes in order to meet the client's dietary needs. Using the recipe, a 3D-printing machine makes the sushi and injects the raw vitamins, proteins, and minerals the client needs.

Sushi Singularity is one of many ventures by a Japanese culinary innovation company called Open Meals.
