Japanese swiss roll recipe

I'm looking for a Japanese swiss roll recipe -- the sort of light, fluffy swiss roll found in bakeries filled with whipping cream as opposed to the slightly heavier Western ones filled with buttercream or jam. Does anyone have one?

- White soft sugar A…20g- Albumen … As many as 4 pieces
- White soft sugar B…70g- ''Nissin pastry flour'' … 40g
- Butter (unsalted)… 40g

custard cream
- Milk … 200cc

butter cream

Please the translation of the recipe must be difficult, and translate directly on the site and look.
