There are shops that you can eat cheaply in Japan.
Here, I introduce three shops of ramen, beef bowl, udon.
1,Ramen / KOURAKUEN (幸楽苑)
KOURAKUEN is a ramen shop spreading nationwide and has about 500 stores.
・Menu (one example among many)
The cheapest menu is 390 JPY (tax-included 421 JPY) with Chinese noodles plainly.
The Gyoza is cheap, too and is 200 JPY (tax-included 216 JPY).
2,Beef bowl / MATSUYA (松屋)
There are some cheap beef bowl shops, but introduce MATSUYA here.
Because miso soup is free.
・Menu (one example among many)
The cheapest menu is 240 JPY at the mini of the beef bowl.
It is 290 JPY with a regular beef bowl.
3,UDON / MARUKAME SEIMEN(丸亀製麺)
The MARUKAME SEIMEN is the udon chain store where is the most popular in Japan now.
It is in not only Japan but also Korea, China, Australia, Russia.
・Menu (one example among many)
The cheapest menu is 290 JPY of the udon.
The large serving is +100 JPY.
The recommendation is cold BUKKAKE UDON.
There is no side dish of 290 JPY, but you can eat leeks and tempura bits free of charge.
I think the cheapest eating out in Japan is around 290 JPY.
Please try to challenge because it is all over Japan.
Even cheap, it is unexpectedly delicious!
