Designated as the "Spoon Vege" line (because they will come in mini cups with a spoon), the flavors are Tomato Cherry and Carrot Orange.
Tomato Cherry's flavor comes made with a combination of cherry juice and tomato paste. By composition, it is 20% fruit juice and 8.5% milk fat (compared to 12 to 14% for the typical Haagen-Dazs ice cream).
Carrot Orange features a blend of concentrated carrot juice, orange juice concentrate, orange pulp, and orange peel. It has the same 8.5% milk fat but less concentrated juice at 5%.
According to RocketNews24, the flavors will come in 100mL (3.7oz) cups for 284 yen (~$2.80 US) each.
Considering that Dreyer's (which is owned by Nestle who also owns Haagen-Dazs) recently started offering fruit and vegetable frozen juice bars over here in the US, it's possible that we might see vegetable ice cream here in the near future.
