A message comes from your noodle supplier: from next month, they’d like to raise the unit price of the noodles. When they tell you that flour and delivery-truck costs are both up, you can’t find a reason to refuse. And yet, raise the price of a bowl and your regulars might drift away; hold it steady and your profit keeps getting shaved.

When you’re told your supplier noodles are going up, a ramen shop has more than one move. Taisei Kikai Kogyo, a noodle-machine manufacturer, has put together why supplier noodles rise in price and the three options a shop has, along with what each is and isn’t suited to.

A shop’s options against a supplier-noodle price increase are mainly these three.

  • Pass it to the price: raise the price of a bowl to absorb the higher cost.
  • Review your sourcing: hold down the cost rise through talks with the supplier on terms, quotes from other suppliers, and a review of the noodle spec.
  • Switch to in-house noodles: make the noodles at your own shop and remove the supplier’s margin and the delivery cost from your cost.

Which one fits depends on your bowls per day and on whether you want to differentiate with the noodle.

1. Why are supplier noodles going up?

The price of supplier noodles includes, besides ingredients such as flour, the cost for the supplier to make the noodles and the cost to deliver them to your shop. The reason for an increase is rarely just one of these; usually several overlap.

  • Flour price: much of the wheat used in Japan is imported, and the price at which the government sells imported wheat to flour millers (the government selling price) is revised twice a year (the April term and the October term), reflecting international wheat markets and exchange rates. When this price rises, it feeds through the price of flour into the cost of the noodle.
  • Logistics cost: from April 2024, the cap on overtime work was applied to vehicle-driving work, including truck drivers. The cap is, in principle, 45 hours a month and 360 hours a year, and up to 960 hours a year even when there are temporary, special circumstances. With a cap on how much one driver can carry, delivery costs have become prone to rising. Supplier noodles, delivered every day, are a product easily affected by this.
  • The supplier’s labor and utility costs: rises in the wages of the people making the noodles and in the electricity to run the machines also ride on the noodle’s unit price.

Sources: Ministry of Agriculture, Forestry and Fisheries, “Government selling price of imported wheat”; Ministry of Health, Labour and Welfare, “Overtime caps for construction, drivers, doctors, etc.” (both confirmed October 26, 2026)

None of these reasons can be stopped by a shop’s own efforts alone. So, as long as you keep using supplier noodles, it’s more realistic to assume that price increases can keep happening.

2. How much does a noodle price increase cut into a shop’s profit?

The impact of a noodle price increase on profit is decided by the increase per ball multiplied by the bowls per day. Even a few yen per ball adds up to a large sum over a year, because it’s an ingredient used every day.

Example (a shop serving 100 bowls a day, 25 days a month, where supplier noodles rise 5 yen per ball)

  • One month: 5 yen × 100 bowls × 25 days = 12,500 yen
  • One year: 12,500 yen × 12 months = 150,000 yen

If you hold the selling price, 150,000 yen of annual profit simply vanishes. The 5-yen increase is a placeholder for the calculation, so replace it with the actual increase you were told and calculate.

Shops with large servings or noodle refills see a proportionally larger impact, since the amount of noodle per bowl increases.

3. The three options a shop has

Each of the three options a shop has against a supplier-noodle price increase has things it is and isn’t suited to.

Option Main advantage Main caution Shops it suits
Pass it to the price No added equipment or labor. Can start right away Risk of losing customers. Faced with the same decision every time the purchase price rises Shops whose regulars are attached to the taste and service and who will accept an increase
Review your sourcing Can be tackled with your current kitchen. Reviewing the noodle spec is also a review of the taste Talks may not stop the increase. Changing suppliers changes the noodle’s taste and texture Shops with no strong attachment to their current noodle and a supplier on good terms nearby
Switch to in-house noodles Removes the supplier’s margin and the delivery cost from the cost. Lets you differentiate with the noodle Needs machine cost, a place to put it, and daily time to make noodles. Takes a trial period to learn the skill Shops with high bowl counts, shops that want to differentiate with the noodle

Pass it to the price

Passing it to the selling price is the quickest method, absorbing the cost rise with no capital investment. If it’s only the noodle’s increase, the per-bowl rise can sometimes be small.

However, revising the selling price means repeating it every time the purchase price rises, and worrying about the effect on customers each time. Some shops review toppings or the noodle amount along with the increase to create a reason customers can accept.

Review your supplier or noodle spec

Reviewing your sourcing is a method you can tackle without changing your current kitchen. After confirming the reason and timing of the increase with the supplier, you ask whether there’s room to discuss terms. Getting a quote from another supplier also tells you whether your current unit price is high or low against the market.

There’s also a method of reviewing the noodle spec. Changing the weight of a ball or the type of flour used can sometimes hold the unit price down. On the other hand, changing the spec also changes texture and taste, so you need to confirm by tasting whether it’s within a range your regulars won’t notice.

Switch to in-house noodles

Switching to in-house noodles is a method that distances you from the cause of the increase itself. Because the supplier’s margin and the delivery cost contained in a ball of supplier noodle come off the cost, what’s affected by increases is limited to the ingredients such as flour used at your own shop and the electricity.

In-house noodles have another advantage besides cost. It’s that you can decide the thickness, hydration, and blend of the noodle to match your own soup. A price increase can also become a chance to differentiate with the noodle.

4. A guide to deciding which option fits

Which of the three options to choose is roughly decided by the answers to the next three questions.

  1. How many bowls do you serve a day: the more bowls, the larger the sum the per-ball difference becomes, and the easier it is to recover the cost of in-house noodles.
  2. Do you want to differentiate with the noodle: if so, in-house noodles have more freedom than a review within the range of supplier noodles.
  3. Can you secure the place and time to make noodles: if you can’t take a place for the machine and daily time to make noodles, in-house noodles aren’t realistic.

If you answer “no” to the third question, combining a price pass-through with a sourcing review is realistic. Conversely, the more a shop has high bowl counts and wants to differentiate with the noodle, the more it’s worth considering in-house noodles. You don’t need to narrow it to one option, either; some shops first review sourcing to buy time and try in-house noodles during that time.

5. How to think about costs when switching to in-house noodles

The cost of in-house noodles is considered by comparing the machine cost against the difference in cost per ball. In our research, supplier noodles are about 40-50 yen per ball and in-house noodles about 18-26 yen (as of October 2026, our research).

Example (with a per-ball difference of about 24 yen, 100 bowls a day, 25 days a month)

  • Cost difference: 24 yen × 100 bowls × 25 days = 60,000 yen a month, about 720,000 yen a year
  • Starting with a rental (from 62,000 yen a month): at 100 bowls a day, the cost difference and the rental fee come out about the same
  • Buying a small machine: dividing the Taisei No.1 body price of 1,688,000 yen (excl. tax) by the about-720,000-yen annual difference reaches the body price in about 2 years 4 months

All are calculations of only the machine body and rental fee, and do not include electricity, the labor time for preparing ingredients and making noodles, or repair costs.

Comparing the rental fee against the cost difference shows that a rental is less a way to profit over long use and more a way to try in-house noodles with your own kitchen and soup. For long use, buying tends to be more advantageous, and the more bowls a shop serves, the faster the recovery. A trial by monthly bowl count is explained in The profit left when switching from supplier noodles to Taisei, and a comparison of adoption methods in Making your own noodles: is it better to “buy” or “rent”?

Example shop: Menya Daito (Kanda, Chiyoda-ku, Tokyo)

A tsukemen shop in the lineage of “Taishoken” in Higashi-Ikebukuro, it blends two kinds of flour and makes a straight thick noodle at higher hydration at its own shop every day. Though a small 14-tsubo shop, by using a space-saving noodle machine it has made in-house noodle-making possible, producing a distinctive noodle at low cost.

6. How to try in-house noodles (with the Taisei noodle machine)

The Taisei noodle machine is a commercial noodle machine with over 30 years of history: Taisei Kikai Kogyo handles design and manufacturing, and the sole distributor Kitchen Techno handles sales and post-installation training. There are ways to check whether in-house noodles suit your shop without buying a machine outright.

  • Free ramen school: a one-day hands-on demonstration that Kitchen Techno holds once a month each in Tokyo and Osaka, and irregularly in Sapporo. You make and taste trial noodles and soup on real equipment.
    Tokyo venue: Tenpos Tokyo Ramen Senmonkan (2-1-14 Higashi-Ayase, Adachi-ku, Tokyo)
    Osaka venue: Tenpos Osaka Ramen Senmonkan (2-1-8 Kitajima, Suminoe-ku, Osaka)
  • Rental: from 62,000 yen a month, you can place it in your own kitchen and try it. You can also discuss switching to a purchase once satisfied.
  • Early delivery: if your opening is near, the standard No.2 keeps stock for early delivery and, when in stock, can be delivered within 1-2 weeks domestically. A reconditioned used machine, when in stock, can be delivered in as little as one week.

There are three models — the No.1 for small shops and trials, the standard No.2 chosen by the most shops, and the No.3 for large-volume preparation — and every model comes standard with a mixer. Body prices are 1,688,000 yen for the No.1, 1,875,000 yen for the No.2, and 2,475,000 yen for the No.3 (all excl. tax, as of October 2026). A Stainless Version, resistant to rust and free of paint peeling, has also begun build-to-order across all models (price on inquiry).

7. Frequently asked questions

Can I refuse a supplier’s price increase?
Whether to accept an increase depends on the terms of the deal between your shop and the supplier. If you don’t accept it, you’ll switch to another supplier or to in-house noodles. Because changing suppliers also changes the noodle’s taste, the realistic step is to first confirm the reason and timing of the increase and ask whether there’s room to discuss terms.
Can I raise a bowl’s price by just the noodle’s increase?
Whether to raise the selling price is the shop’s call, but if not only the noodle but also the soup’s bones and utilities are up, raising by just the noodle’s share won’t fully restore profit. It’s surer to write out the increase for each ingredient once, confirm how much a bowl’s cost has risen, and then decide.
If I make noodles in-house, am I free from flour price increases?
Even with in-house noodles, you’re affected if flour rises in price. What in-house noodles take off the cost is the supplier’s margin and the delivery cost.
Once I decide to switch to in-house noodles, how long until I can serve the noodles?
The time until switching to in-house noodles is decided by arranging the machine and the time for noodle trials. With the Taisei noodle machine, the standard No.2 keeps stock for early delivery and can be delivered within 1-2 weeks domestically when in stock. New No.1 and No.3 are build-to-order, taking from several weeks, and a reconditioned used machine can be delivered in as little as one week when in stock. You can learn the basics of operation in one day at the free ramen school, but to finish a noodle that suits your own soup, you should expect a period of repeated trials.

A supplier-noodle price increase can also become a chance for a shop to review how it sources its noodles. First, calculate the annual impact at the increase you were told, and consider which of the three options fits your own shop.
