The short answer: Buy Japanese Wagyu from a supplier who gives you the animal's 10-digit ID, its JMGA grade and BMS, and the farm before you pay. You can look the ID up in Japan's cattle registry yourself. For a dinner, ordering about two weeks out leaves room for shipping, and each frozen pack needs at least a full day to thaw in the fridge.

Where can you buy real Japanese Wagyu for a dinner?
There are three places to get it in the US. Online importers and retailers ship it frozen, cut by cut. Wholesale distributors sell to restaurants and other businesses. And a restaurant or butcher that already carries it may sell you a piece. All of it comes from one of the 15 Japanese plants certified to export raw beef to the United States [1].
So it's fair to judge a supplier by what it can document. A5 is also less rare than the price suggests. Most Wagyu graded in Japan now comes out A5 (see our grades guide for more info), so the questions below matter more than just the letter on the label.
What should you ask a Wagyu supplier before you pay?
If a supplier can't give you this information, be wary! This is all standard Wagyu tracing information:
| Ask for | A good answer | Why it matters |
|---|---|---|
| The 10-digit individual ID | A number you can enter in the National Livestock Breeding Center's English search | It returns the breed, sex, birth date, every farm or market the animal moved through, and its slaughter date [2] |
| The grade, letter and number | "A5, BMS 10" or "A4, BMS 6" | "Grade 5" with no letter, or A5 with no BMS, leaves out what you're paying for. A5 needs BMS 8 to 12 |
| The grading certificate | A copy, keyed to that ID | The Japan Meat Grading Association issues it to the producer, the carcass buyer, and the shops and restaurants that bought cuts from them, never to consumers [3] |
| The farm and prefecture | A named farm | The registry shows where the animal was raised; the supplier should know why they buy from that farm |
| Whether every piece is from one animal | Yes, with one ID | Eight plates from eight different carcasses can look and eat differently side by side |
| Pack weight and thickness | Per pack, in ounces or grams | You portion from it |
Then it's worth checking the ID yourself. It takes a minute, and the authenticity guide walks through what a real record shows. Takemitsu-chan's, for example, is 1493019197, and her grading record is on her page.
How far ahead should you order Wagyu for a dinner?
Working backward from the dinner, two weeks is the window I'd plan around.
Frozen beef almost always ships at the beginning of the week, to avoid spoilage if a package sits over the weekend. Ours leaves our Illinois warehouse Monday through Thursday, only on a day it's expected to arrive before the weekend, so an order made on our website may wait a few days (or until the following week) to ship. Transit from there is one to three business days, depending on the state. The cart shows an estimated ship and arrival date before you pay.
Thawing takes longer than most people think: you should budget for 24-48 hours for retail cuts, up to 3-4 days for a whole subprimal [5].
| When | What to do |
|---|---|
| About 14 days out | Confirm the cuts and grade with the client, then order |
| Delivery day | Freezer, at 0ºF or below, still in the vacuum packs |
| 24–48 hours out | Move packs to the fridge. A day for 1″ steaks, two for a 2 lb roast |
| 20–30 minutes before searing | Out of the fridge, still sealed |
Steaks thawed in the fridge keep 3 to 5 days before cooking [5], which gives you room if the client moves the date. If a pack is still frozen on the day, USDA says it's safe to cook from frozen, at about 50% longer cooking time [5]. That's best kept as a fallback.
Can you thaw Wagyu quickly?
You can. USDA's quick method is a cold water bath: keep the pack sealed, submerge it in cold water (ice water works too), and change the water every 30 minutes so it stays cold. A 1 lb pack thaws in about an hour, and a 3 to 4 lb roast in two to three [5]. It's perfectly safe by USDA's standards, but meat thawed in water should be cooked right away [5], so plan to use it that day.
A fast thaw may cost the meat some quality, though, so a gentle thaw in the fridge is still clearly the better choice for a dinner you've planned. The water bath is for the day a pack didn't make it out of the freezer in time.
Does frozen Wagyu hold up for a dinner service?
Yes, if it stays frozen until you thaw it on purpose. USDA's guidance is that food held constantly at 0ºF stays safe, that only quality declines over long storage, and that unopened vacuum packs can go into the freezer as they are [4]. Fridge-thawed meat can be refrozen, with some loss of quality [5], so it pays to thaw only what you'll serve.
Ours arrives vacuum sealed in an insulated box with dry ice. When it lands, oven mitts help with the dry ice; the packs go into the freezer, and any pack that has softened but is still cold can go to the fridge to cook within a couple of days. The unboxing guide covers the dry ice. If a box arrives thawed, photograph it and email moo@peakwagyu.com the same day.

How much Wagyu do you need per guest?
Less than you'd buy of an American steak. Plan on 4 to 8 oz of raw Japanese Wagyu per guest when it's the main course, and 1 to 2 oz when it's one course of several. It's much fattier than Angus, so guests reach their limit sooner, and a smaller portion goes further. A5 is richer still, so you might take each range down by about an ounce.
For a table of any size, it's usually easier to cook whole steaks and slice them in the kitchen than to plate a steak per guest. That's fewer sears to manage, every plate gets the same doneness, and you set the portion.
How much Wagyu per person works through every format, from a tasting course to a yakiniku dinner, along with what each one costs.
Should you buy from a whole-cow drop or a broker?
It depends on whether you need the same cut every week or one animal for one table.
| Whole-cow drop | Broker or distributor | |
|---|---|---|
| Animals | One, with one ID on every pack | Often many carcasses and brands |
| Cuts | Everything the cow yielded, including zabuton, misuji and ichibo | Usually the cuts restaurants reorder |
| Grade | Whatever that cow graded | You can usually choose A5 |
| Supply | A fixed window, and cuts sell out | Repeat orders of the same cut |
| What to ask | When the next cow arrives | The ID for each piece in the case |
We sell the drop model: one cow, every cut sold individually, shipped frozen. The cuts guide explains what each cut is and how to cook it.
Frequently asked questions
Where can I buy Japanese Wagyu online?
From US importers and retailers that ship Japanese Wagyu frozen, cut by cut. Before you order, ask for the animal's 10-digit individual ID, the JMGA grade with its BMS number, and the farm, and check the ID in the National Livestock Breeding Center's registry. A seller that can't produce the ID is a reason to keep looking.
Can a private chef buy Wagyu wholesale?
Wholesale distributors sell to businesses, so it's worth asking whether they'll open an account for a private chef or caterer and what their minimum order is.
How do I know Japanese Wagyu is real?
Enter its 10-digit ID at the National Livestock Breeding Center's English search. Real Japanese Wagyu returns its breed, sex, birth date and every move up to slaughter. The grade comes from the Japan Meat Grading Association, which issues grading certificates to businesses that bought the carcass or its cuts, so ask your supplier for one.
How far in advance should I order Wagyu for a dinner party?
About two weeks. Frozen beef usually ships only on weekdays that let it arrive before the weekend, so an order can wait several days to go out. Then it needs at least a full day in the fridge to thaw, longer for a roast.
Do I need A5 Wagyu for a private dinner?
Not necessarily. A5 is the richest grade and suits one or two bites in a tasting menu. A4 eats more easily as a main course. Our current cow, Takemitsu-chan from Takeda Farm in Hokkaido, graded A4 with BMS 6. If a client has asked for A5 by name, buy A5.
