It looks like tonkatsu specialty restaurant “Matsunoya” has released a coupon that lets you get a roast pork cutlet set meal for just one coin (550 yen including tax).
✨One-coin coupon is live✨
Starting today at 11:00, for “1 week only,”
we’re launching a tax-exclusive
【one-coin coupon】‼️

Apparently, it started because their official X account (@matsu_noya) reached 300,000 followers. It’s a one-week-only deal from Sunday, May 18 at 11:00 to Sunday, May 25 at 11:00.
One-Coin Eligible Menu Items
The following three items are eligible, and all are 550 yen including tax.
- Roast Pork Cutlet Set Meal + Potato Salad Topping (usually 780 yen) → 550 yen
- Roast Pork Cutlet Set Meal with Oni-oroshi Grated Daikon and Ponzu (usually 790 yen) → 550 yen
- Miso Roast Pork Cutlet Set Meal (usually 790 yen) → 550 yen
Saving up to 240 yen is pretty solid.
There’s Also a 30% Off Coupon
There’s another coupon that was released on May 15, and this one seems to offer up to 30% off on six menu items. It’s part of the campaign celebrating 300,000 followers, and apparently they’ve prepared coupons for 300,000 meals.

The photo is from “Matsunoya” is opening near Hanshin Nishinomiya, so we tried the “Roast Pork Cutlet & One Piece of Fillet Cutlet Set” at the Nishida-cho Matsunoya【Nishitsu Gourmet】.
For example, the Double Roast Pork Cutlet Set Meal goes from 1,050 yen to 730 yen. Combined with the one-coin coupon, this seems like a pretty good-value period.
How to Use the Coupon
Just open the coupon post on Matsunoya’s official X account (@matsu_noya) and show your smartphone screen at the store. It looks like you can use it as many times as you like during the campaign period.
We’ll include it here on Nishitsu too ↓

So taking a screenshot should do the trick〜

In Nishinomiya City, there’s one in Nishida-cho,

near Hanshin Nishinomiya Station,

and at Imazu Station too.
Lastly
It’s nice that you can use it as many times as you want just by showing your smartphone screen. There are several locations in Nishinomiya City, so if you’re in the mood for a hearty lunch or dinner today, definitely check it out〜
