Shiso

A Japanese herb from the mint family with a flavor that sits between mint, basil, and anise — brighter and more aromatic than basil, without mint's menthol. Green shiso is most common; red (aka shiso) is used primarily in pickling and umeboshi.

In Italian-Japanese cooking, shiso functions as basil's Japanese analog — it works in a gremolata (shiso, lemon zest, garlic), torn over pasta, or as a garnish wherever basil would go. The structural similarity to basil in function, despite completely different flavor, is part of what makes Japanese-Italian fusion coherent rather than arbitrary.
