Look up vocabulary and Kanji, translate Japanese into multiple languages using JP Dictionary (JP Jisho/JP 辞書/JP じしょ)
Finally, I found this. It's so cool.

This extension is cool, because when you highlight a word, phrase, or sentence, then click on the purple dictionary icon that appears, you can then click on the speaker icon 🔊 and a cute Japanese voice will pronounce it for you! (Rikaikun and Rikaichamp don't have this speech feature.) Neat-o! 👍 I will use this in addition to the other extensions I mentioned. PS: If you have uBlock Origin, make sure to disable it, otherwise the extension will not work correctly. I've found that uBlock Origin interferes with all the Japanese translating extensions.
