SITE MODELTimes and fail rates below are site-model estimates — not in-game stats.
Six-Station Solo vs 6-Player Efficiency Comparison Table
| Station | Solo Time | 6-Player | Fail Rate | Fail Penalty |
|---|---|---|---|---|
| PREP | 8.2m/10 bowls | 3.1m/10 bowls | 12% | Stockout → cancel -¥800 |
| SIMMER | Always watch | 1 dedicated | 8% | <85°C → Umami -18 / Aroma -22 |
| COOK | 15s/bowl | 12s/bowl | 15% | Overcooked → critic -2★ |
| BUILD | 22s/bowl | 14s/bowl | 10% | Tilt >15° → visual -30 pts |

PREP Station: Genkotsu Split, Chashu Roll & Vegetable Pre-Cut Field Guide
Prep speed sets your rush-hour buffer. Stock 10+2 portions pre-shift. Split bones, cold-soak 30min, skim blood foam — skip this and tonkotsu smells off by hour two.
⌨ L-click mash split / Shift+chop scallions batch
⚡ Split → soak → slice chashu → peel ajitama (120s chain)
SIMMER Station: Kombu 60°C · Genkotsu 95°C · Hold Pot 86–92°C Control
Umami synergy = glutamate × inosinate. Below 85°C fat separates; Brix 8.5–11.2° is the golden band. This stage sets ~80% of your score.
⌨ Fine-tune temp slider / low flame ±1°C hold
⚡ Kombu 60°C → bone 95°C → skim → 88°C hold
COOK Station: Barikata 15s · Futsu 30s · Double Basket Shake
Double snap the basket — noodle water dilutes broth fast. Boiler above 98°C. Serve below 86°C and critics dock stars.
⌨ Auto timer on drop / double shake -92% water
⚡ Drop → 15s → double shake → pass to BUILD (<28s)
BUILD Station: 15ml Tare · Mayu Last · Physics Plating
Plating balance hits visual critic scores. Black garlic mayu goes last. 15ml tare in bowl bottom — never dump into the stockpot.
⌨ Drag physics placement / mayu click last
⚡ Tare 15ml → ladle → noodles → toppings → mayu (18s)
SERVE Station: 7:3 Draft Beer · Hanetsuki Gyoza · Broth Temp Hold
Every 5s on the pass cools soup 1°C. 7:3 foam line = +18% tip bonus. Hold foam 8s post-pour for Perfect Serve.
⌨ Hit 7:3 line / triple sprint delivery
⚡ Beer 7:3 → flip gyoza → sprint ramen (12s triple)
RESET Station: Dishwash · Shuriken · Extinguisher
Dishwashing is the #1 co-op bottleneck (22% fail rate). Bell rings, shuriken flies. Grease fire = extinguisher only.
⌨ Mash dishwash speed / bell → instant shuriken
⚡ Collect → wash → dry → reuse (35s/5 bowls)
BROTH UMAMI FORMULA LAB
Japanese Ramen Simulator Broth Umami Formula: Synergy Theory & Temperature Equation
Umami Score = (Glu[Kombu] × Ino[Genkotsu/Katsuobushi])^0.72 × USM × Emulsion(T)
USM (Umami Synergy Multiplier) = 1.0 + 0.15×min(Glu,Ino)/100. Both Glu+Ino above 90 → USM=1.35. Emulsion(T) = 1.0 (86–92°C) / 0.62 (<85°C) / 0.88 (>95°C)
BRIX Brix 8.5–11.2° balances umami, aroma, and cost. 7h tonkotsu +2.1° Brix; kombu 60°C 60min +0.8°.
COLLAGEN Collagen hydrolysis curve: 95°C×4h → 80% gelatinization → +12 emulsion. 100°C 48h+ → fat cap → Aroma -15.
Kombu glutamate and genkotsu/katsuobushi inosinate multiply — not add. Drop below 85°C and Emulsion falls to 0.62, critic stars fall together. Tune all three variables in the Broth Builder.

NEW GAME WALKTHROUGH DAY 1–3
Japanese Ramen Simulator New Game Walkthrough: Days 1–3 Shop Expansion Guide
Day 1 · Target ¥12,000
One menu item (black garlic tonkotsu + Barikata). Prep ten portions. Buy ¥12,000 holding pot first. Skip ¥80,000 decor — cash below ¥25,000 = Day 4 bankruptcy. Waste target <8%.
Day 2 · Target ¥15,000
Memorize Tanaka's sheet, land one 5★ (+¥50,000 tip). Practice 7:3 beer off-peak. Next buy: boil timer ¥8,500.
Day 3 · Target ¥18,000 (¥45,000 cumulative)
Two-player split PREP+SIMMER / COOK+BUILD. Buy dishwasher speed ¥15,000. RESET bottleneck sets revenue ceiling. Week 1 end: 2 critics at 5★ + ¥60,000 cash.
⚠ Bankruptcy warning: spending ¥40,000+ on decor/BGM/premium dishware Days 1–3 means Day 4 supply shortage Game Over. Broth temp and dishwash first — decor after Day 10.
