How to Buy Eggs in the United States
US eggs differ from Japanese eggs in safety standards, labeling, and how you shop for them. Raw consumption is generally not safe, labels are confusing, and you need to inspect before buying.
US eggs are not the same as Japanese eggs. The safety assumptions, what the dates mean, and how you buy them are all different.

Japan vs. US
Japanese eggs are produced for raw consumption. Hens are vaccinated against Salmonella, eggs are sterilized and machine-inspected, and the 賞味期限 is set at 14–21 days — the safe window for eating them raw. After that, they're still fine cooked.
US eggs assume cooking. The FDA recommends cooking until both white and yolk are firm. Hens are not systematically vaccinated, and the sell-by date is an inventory label for the store, not a raw-consumption window. Eggs are safe to eat (cooked) for 3–5 weeks past the pack date.
**Raw egg dishes require pasteurized eggs.** TKG, sukiyaki dipping, 温泉卵 — all carry Salmonella risk with standard US eggs. The one brand currently selling pasteurized shell eggs in the US is **Fearless Eggs** (cage-free, Certified Humane, pasteurized in warm water). They are expanding to retailers nationwide — check their store locator at eatfearlesseggs.com or ask your local store. Availability in Massachusetts is limited; Maruichi may carry them occasionally. Look for a "P" stamp on the shell. If you cannot find pasteurized eggs, cook fully.

Labels
If you're used to Japanese eggs — rich yolk, actual flavor, deep color — you'll find most US eggs disappointing. The tier you buy determines whether the egg tastes like anything at all.
**Pasture-raised** — Closest to Japanese egg quality. Hens eat insects, seeds, and vegetation outdoors. Yolks are darker, flavor is noticeably richer. Look for a Certified Humane seal (without it, the term is unregulated and meaningless). Most expensive tier.
**Free-range** — Acceptable middle ground if pasture-raised is out of budget. Some are great quality, such as Free Range Heirloom Blue Eggs from Trader Joe's. Hens have some outdoor access. Yolks are slightly better than cage-free but the difference is inconsistent across brands.
**Cage-free** — Indoors only. Marginally better than conventional in welfare terms, but the taste difference is negligible. If you're coming from Japanese eggs, these will taste flat.
**Conventional (unlabeled)** — Battery cages, cheapest. Pale yolks, watery whites, no flavor to speak of. Fine for baking. Difficult to enjoy as a standalone dish if your reference point is Japanese eggs.
**In short:** Pasture-raised with Certified Humane if egg flavor matters. Free-range if budget is tight. The bottom two tiers are adequate as cooking ingredients but won't satisfy you as a fried egg or omelette.

How to Shop
Open the carton in the store. Check for cracked shells and eggs stuck to the bottom (stuck = cracked and dried). In the US, no one checks for you — this is your job.
If the carton has a tamper-evident seal you can't break, inspect through the plastic and check at home. Most stores accept returns for broken eggs.
The 3-digit number on the carton is the Julian pack date (001 = Jan 1, 365 = Dec 31). A higher number means more recently packed. More useful than the sell-by date for judging freshness.
Store in the coldest part of the fridge (main shelf, not the door). US eggs are washed and the natural coating is gone, so they must stay refrigerated.

FAQ
Can I eat American eggs raw?
Not with standard eggs. US eggs are not produced for raw consumption. If you want to make TKG or use raw egg for sukiyaki, look for **Fearless Eggs** — currently the only pasteurized shell egg brand in the US (look for the "P" stamp). Availability varies by store; check eatfearlesseggs.com for locations. If unavailable, cook until fully set.
What does "cage-free" actually mean?
Indoor barn, no cages, no outdoor access. About 1 square foot per bird. Tastes about the same as conventional. For actual flavor closer to Japanese eggs, you need pasture-raised with a Certified Humane seal.
Do I need to check the eggs before buying?
Yes. Open the carton, look for cracks and stuck shells. Staff will not do this for you. If one is broken, pick a different carton.
