Field guide
Every episode in this guide has a packed lunch matched to it. Under ¥600. Under 15 minutes to make the night before. Tastes better eaten outside, somewhere you've never been.
You're not taking a day off — you're relocating your Tuesday. You bring the laptop, you bring the lunch, and you eat it somewhere that isn't your kitchen. That's the whole thing.
All the recipes use ingredients available at any Japanese supermarket or large convenience store. Most can be prepped in under 15 minutes the night before. The cost cap is ¥600 per batch (serves 2 — or one generous portion). Nothing requires special equipment beyond a saucepan and a container that seals.
Each episode page includes its matched recipe in full — ingredients, method, cost, prep time and cook time. The full recipe is shown inside the episode. Open any episode and scroll down to the Packed lunch section.
Rice triangles filled with umeboshi, wrapped in nori. The classic. Under ¥400. Works cold, works warm, works at a park bench.

The foundation of half the recipes. Cook a larger batch on Sunday, refrigerate, and you have the base ready for the week. Any supermarket sells it — koshihikari is the standard variety.
One leak-proof container for the main, one small jar for dressings and sauces. Daiso or any hundred-yen shop sells exactly what you need.
The miso soup flask recipe (Week 5) and the hiking onigiri set (Week 3) both use hot liquid. A 400ml thermos keeps things warm for 4–5 hours.
