Tanaka Tsuyoshi

Hakata Old-School Ramen Critic (Traditionalist)
🍜 View site-model recipe →

Prototype background: Former Hakata yatai owner turned critic in our pre-release reference sheet. He judges tonkotsu emulsion, noodle bite, and broth temperature with zero tolerance for shortcuts—the persona below is a site prototype, not a confirmed in-game boss.

Pre-visit omen (preview · unconfirmed):

⚡ HUD flashes amber "Gourmet Incoming" + copper bell chime 8s before spawn. Broth pot thermometer icon pulses red if < 88°C.

Visit cycle (estimated):

Appears every 3–4 in-game days after Day 5. Triggers during lunch rush (11:00–14:00) when shop cleanliness ≥ 80%.

Serve timer (estimated):

Hard cap 90s from seating to delivery. Stars: 90s=5★ · 95s=4★ · 100s=3★ · 105s=2★ · 120s+=1★ (recipe-correct floor).

5-star window (estimated):

Order must reach table within 45s for 5-star margin. Each 5s over deducts 1 star (minimum 2 stars if recipe is correct). Broth < 82°C at pass = instant -2 stars regardless of speed.

Fallback build (site model):

Emergency 3★ floor: Rich Tonkotsu + Black Mayu + Barikata 15s + thick chashu. Pre-warm Mayu to 60°C. Skip nori if prep behind — temperature beats garnish.

  • ★Noodle timer must be between 14s and 16s (+40 pts).

Perfect flow (site model):

  2. 2.Boil Barikata noodles at exactly 15s — start timer on basket drop.
  3. 3.Ladle broth at 88°C, drizzle Mayu last, deliver within 40s for safety margin.
5-star line (fiction)"Magnificent emulsion and blistering hot soup! That firm bite is pure Hakata craftsmanship. 5 STARS!"

Michelin Food Columnist (Gourmet Aesthetician)
🍜 View site-model recipe →

Grand Master of Japanese Culinary Arts (The Final Judge)
🍜 View site-model recipe →
