Money is essential in Yakuza Kiwami for buying healing items, upgrading equipment, and enjoying Kamurocho's leisure activities. While fighting street thugs provides some cash, these strategies will help you accumulate wealth much faster.

- Gambling: Master games like Blackjack or Poker. Save before playing and reload if you lose too much.
- Mahjong/Shogi: These can be lucrative once you understand the rules and strategies.
- Substories: Many substories offer significant cash rewards upon completion.
- Selling Valuables: Some items found in lockers or as rewards can be sold for a good price.
- Bouncer Missions: Available later in the game, these offer challenging combat scenarios with high monetary rewards.
- Pocket Circuit: Once you invest in good parts, winning races can be a consistent source of income.
Diversify your money-making efforts to ensure a steady flow of yen.
