About Hakoniwa Base Ball
Hakoniwa Base Ball is a baseball management simulation that mirrors Japan's professional league. Players handle every front‑office task—draft, free agency, trades, contracts, scouting and stadium finances—while the game can simulate a season instantly or run each at‑bat pitch by pitch.
The title lets you configure league size, team count and season length, edit players, teams and ballparks via a bundled CSV editor, and watch a living world evolve across generations with aging, retirements and record‑keeping.
01 / THE GUIDE
League Configuration
You can set the league from a 12‑team Japanese‑style format up to 30 clubs across six leagues, choosing team count and season length before starting a new game.
These settings let you design a competitive landscape that matches the scale you prefer, letting you shape the competitive landscape before each new game.
- Start with a smaller league to learn the mechanics before expanding.
- Note down your preferred settings so you can recreate them later.

Front‑Office Management
The game covers draft, free agency, trades, contract talks, multi‑stage salary negotiations, multi‑year deals with buyouts and retirement discussions, all affecting team performance and finances.
Scouting introduces observation error; investing more in scouting reduces the fog and reveals a player's true ability over time.
- Allocate scouting funds early to lower rating uncertainty for key prospects.
- Watch stadium expenses; excessive renovations can strain the budget.

- Use automatic simulation for long seasons to save time.
- Pause at critical at‑bats to test different strategic choices.
