Yakuza 1&2 HD edition already has an easy mode, but if that is still too hard for you, you are in luck. SEGA is planning to update the game on November 15th with even easier modes. Like “Easy + Heat Up Mode”. This will keep the enemies easy and give you the ability to reach heat mode faster.
Yakuza 1&2 HD edition comes out in Japan on November 1st. SEGA has announced no plans to release this collection in the West.
