Preheat your oven to 325°F (163°C). Grease a 9-inch springform pan and line the bottom with parchment paper.
In a large mixing bowl, beat the softened cream cheese with an electric mixer until smooth and creamy.
Gradually add the granulated sugar, mixing until well combined.
Add the heavy cream, sour cream, and vanilla extract to the mixture, and continue to beat until smooth.
Add the eggs one at a time, mixing well after each addition.
Sift the flour, matcha powder, and salt together, then gently fold them into the cream cheese mixture until just combined.
Stir in the lemon juice for added flavor.
Pour the batter into the prepared springform pan and smooth the top with a spatula.
Bake in the preheated oven for 50-60 minutes, or until the center is set but still slightly jiggly.
Turn off the oven and leave the cheesecake inside for an additional 30 minutes to cool gradually.
Remove from the oven and let it cool to room temperature before refrigerating for at least 4 hours or overnight.
Once chilled, carefully remove the cheesecake from the springform pan and slice to serve.
