Creating a stunning Japanese Strawberry Shortcake is straightforward when you follow these detailed steps:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C) and greasing an 8-inch round cake pan.
2. Beat Eggs and Sugar: In a mixing bowl, beat the eggs and granulated sugar together until the mixture becomes light and pale.
3. Add Wet Ingredients: Stir in the milk, vegetable oil, and vanilla extract until fully combined.
4. Sift Dry Ingredients: In a separate bowl, sift together the flour and baking powder.
5. Combine Mixtures: Gradually fold the dry ingredients into the wet mixture until no lumps remain.
6. Pour into Pan: Pour the batter into the prepared cake pan, spreading it evenly.
7. Bake: Place in the oven and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
8. Cool the Cake: Remove from the oven and allow the cake to cool in the pan for 10 minutes. Then transfer to a wire rack to cool completely.
9. Prepare Whipped Cream: In a separate bowl, whip the heavy cream with the powdered sugar until soft peaks form.
10. Slice the Cake: Once the cake is completely cool, slice it in half horizontally to create two layers.
11. Layer the Cake: Place the bottom layer on a serving plate. Spread a layer of whipped cream on top, followed by a layer of sliced strawberries.
12. Add the Second Layer: Place the second layer of cake on top and repeat the process, spreading whipped cream and strawberries.
13. Decorate: Garnish with additional strawberries on the top for a stunning presentation.
