Two new English words I found mispronounced in Japanese

During my daily reading of the Japanese Daily Sun (Nikkan San) newspaper, two words have baffled me: "Jagujii" (ﾆ淡ﾆ叩ﾆ丹ﾆ淡ﾂー) and "Kajino" ( ﾆ谷ﾆ淡ﾆ知).

"Jaguji" is supposed to be "jacuzzi". So it should've been written and pronounced as "jakuuji" (ﾆ淡ﾆ叩ﾆ誰ﾂーﾆ淡). Then I realized that the Japanese word for "water faucet" is "jaguchi," so that might have contributed to the confusion.

"Kajino", from the context I found out, is "casino".
Would've been better as Kashiino (ﾆ谷ﾆ歎ﾂーﾆ知)

But then again, I can never for the life of me convince any Japanese person that their pronunciation of "major" is incorrect.

First, these words are not English, but Italian. Transcribed from Italian, it should be "jakujji" ﾆ淡ﾆ槌槌誰ﾆ鍛ﾆ淡 and "kaji-no" ﾆ谷ﾆ淡ﾂーﾆ知, not "jakuuji" nor "kashiino".
The pronunciation they use in Japanese is visibly neither Italian, nor English, but French.
