Loanwords from the Japanese language in Hawaiʻi appear in various parts of the culture. Many loanwords in Hawaiian Pidgin (or Hawaiian Creole English) derive from the Japanese language. The linguistic influences of the Japanese in Hawaii began with the first immigrants from Japan in 1868 and continues with the large Japanese American population in Hawaiʻi today.
There are other Japanese words common among the Japanese American population (such as "okazu" and "obaachan"), but not as well-known among Hawaiʻi's general population. Such words have not been included here, nor have Japanese words which have entered the English language on a national level, such as "anime," (ja:アニメ) "karaoke," (ja:カラオケ) "samurai," (侍) and "sushi" (ja:寿司). Hawaiʻi is also unique in the United States in that Japanese loanwords often retain Japanese pronunciation, as in the tapped "r" sound even in words that have entered the American English dictionary such as "karaoke" and "karate."
However, as several varieties of Japanese cultural influence in the US in general has increased over the years, it has further bolstered the uses of Japanese terminology in Hawaiʻi. Japanese food has increased in popularity and availability, most notably in the history of sushi in the US and Top Ramen, plus in the 21st century, ramen restaurants. Poke restaurants, centered around the Hawaiian dish, also have food with Japanese influences. Another variety of cultural influence has been the increasing fandom and availability of anime and manga as early as the 1980s with that era's Viz Japanese comics in English and Mangajin magazine. This fandom brought in the name "cosplay" and expanded its practice in a wider audience.
Some words are not from the standard Japanese language. They instead originated from Japan's regional dialects. For example, the word "bobora" is said to be spoken only in certain prefectures, especially in western Japan where many of the Japanese immigrants came from. It originates from the Portuguese word abóbora meaning Japanese pumpkin.

- Musubi: Rice triangle wrapped in dried seaweed; may or may not have something in the middle, like a pickled ume or bits of fish. Spam musubi has a piece of SPAM luncheon meat on top. In Japanese the word onigiri is more commonly used for rice balls. Without further clarification, "musubi" usually implies the triangle variety (round balls of rice are only eaten at funerals).
- Shoyu (ja:醤油): Soy sauce. "Shoyu rice" is "soy sauce" sprinkled over rice. "Shoyu x" is some ingredient x cooked in soy sauce, e.g. "Shoyu chicken", "shoyu pork", "shoyu tofu". This term is so widely used that most Hawaiian residents are unaware that is not the widely used English language term for soy sauce.
- Sukiyaki (ja:すき焼き): Thin slices of beef, vegetables, and tofu simmered in a skillet or pan in sukiyaki sauce. It is also the title of a No. 1 hit song in the U.S. made popular by Kyu Sakamoto in 1963. The Japanese title of the song is "Ue o muite arukō—it has nothing to do with the food product.)

- Hanakuso: Dried nasal mucus. Hana means nose, and kuso means waste. Kuso in Japanese typically refers to human excrement. This compound is also found in standard Japanese.

- "Kikaida": After the television series of the same name become enormously popular in Hawaiʻi, "Kikaida" became a generic name for children's shows featuring superheroes.
- Shishi: Urine or urination, used in "go shishi" or "make shishi". The Double-Tongued Dictionary gives three possible etymologies for "shishi": imitative from the sound of urinating, Japanese reduplicated shi from shiko "urinate" (sic., probably shito 尿 "urine"), or Portuguese xixi "urinate". There is a Japanese kanji joke based on 五-四-四 "5-4-4", which can be read go-shi-shi in Japanese. Thus, “I gotta five-four-four” is a Pidgin euphemism for "I gotta go shishi".
- Zori: Rubber thonged slippers, often called flip-flops in the continental U.S. Also zoris (plural). Synonymous with "slippers" or "slippahs". From the Japanese word zori (ja:草履). Called "beach sandal" (ja:ビーチサンダル) in standard Japanese.
