Unfortunately, there are no  Jollibee stores  in Japan. There was a rumor that earlier this year “Jolybee is considering opening stores in Japan.” However, it did not come true. It is reasonable. In Japan, the hamburger chain competition is intense.
Of course, the biggest player in Japan is McDonald’s. And Mos Burger, Lotteria, Freshness Burger follow. These shops are originating in Japan. Also, First Kitchen Wendy’s, Burger King etc. There are also many small chain stores and independent shops.
By the way, I have seen Wendy’s at the aquarium in Manila. I also used Burger King at Manila Airport Terminal 3. Needless to say, I frequently used Jollibee.
Oh, McDonald’s in the Philippines has a rice menu, but it is not in a Japanese hamburger shop. Exceptionally, Mos Burger has a rice burger that replacing the buns with rice.
In the Philippines, Jolyby occupies the majority of sales of the restaurant industry, but Japan has a wide variety of restaurants. Therefore Japanese go to other shops when they want to eat rice dishes.
