On a 6-inch square of wax paper, spoon out the crepe batter, smoothing into a 5-inch circle. Lay one mochi slice on top. Place onto a plate and heat in the microwave for 30 seconds.
Peel off the wax paper while still warm. Add 2 strawberries and a spoonful of adzuki paste. Fold the edges of the crepe up and around the filling. Allow to cool slightly then sprinkle with matcha before serving.
