Sending JSON obj with Japanese characters from Python to Javascript

I have a Python3 function that when called will return a json object which looks like this:

finished python tags look like this:
{'tags': {'releaseArtist': ['Shuichi Murakami', 'Nobu Caine', 'Electro Keyboard Orchestra', 'Mash', 'Loser', 'Ponta Box', 'Mobo Band', 'JOQR DJ Girls', 'Miro Takebi Trio', 'Nobu-Zans', '7 Seven', 'Ponta Unit'], 'releaseInfo': ['Welcome To My Life', '1998', 'Japan', 'JVC', 'Jazz'], 'tracklist': ['Jaco Pastorius Medley = ジャコ・パトリアス・メドレー', 'I Want You Back = アイ・ウォント・ユー・バック', 'Travelling = トラベリング', 'Ive Got You Under My Skin = アイヴ・ガット・ユー・アンダー・マイ・スキン', '青い山脈', 'Oh! Darling = オー！
ダーリン', 'Jane Birkin Medley = ジェーン・バーキン・メドレー', '津軽 ～ 南部俵積み唄', 'It Might As Well Stay Monday From Now On = 月曜はブルーな日', 'Time Is On My Side = タイム・イズ・オン・マイ・サイド', 'We Can Talk = ウィ・キャン・トーク', 'Left Alone = レフト・ア
ローン', 'ヨイトマケの唄', 'Mambo No. 5 = マンボ・ナンバー5', '(The White Room ～ Sunshine Of Your Love) ～ Knockin On Heavens Door = 天国への扉', 'Welcome To My Rhythm [こんなオイラに誰がした] ～ 嵐を呼ぶ男'], 'combinations': ['Welcome To My Life 1998', 'Shuichi Murakam
i 1998', 'Shuichi Murakami Welcome To My Life', 'Shuichi Murakami Welcome To My Life 1998']}}
json data =  {'tags': {'releaseArtist': ['Shuichi Murakami', 'Nobu Caine', 'Electro Keyboard Orchestra', 'Mash', 'Loser', 'Ponta Box', 'Mobo Band', 'JOQR DJ Girls', 'Miro Takebi Trio', 'Nobu-Zans', '7 Seven', 'Ponta Unit'], 'releaseInfo': ['Welcome To My Life', '1998', 'Japan', 'JVC', 'Jazz'], 'tracklist': ['Jaco Pastorius Medley = ジャコ・パトリアス・メドレー', 'I Want You Back = アイ・ウォント・ユー・バック', 'Travelling = トラベリング', 'Ive Got You Under My Skin = アイヴ・ガット・ユー・アンダー・マイ・スキン', '青い山脈', 'Oh! Darli
ng = オー！ ダーリン', 'Jane Birkin Medley = ジェーン・バーキン・メドレー', '津軽 ～ 南部俵積み唄', 'It Might As Well Stay Monday From Now On = 月曜はブルーな日', 'Time Is On My Side = タイム・イズ・オン・マイ・サイド', 'We Can Talk = ウィ・キャン・トーク', 'Left Alone =レフト・アローン', 'ヨイトマケの唄', 'Mambo No. 5 = マンボ・ナンバー5', '(The White Room ～ Sunshine Of Your Love) ～ Knockin On Heavens Door = 天国への扉', 'Welcome To My Rhythm [こんなオイラに誰がした] ～ 嵐を呼ぶ男'], 'combinations': ['Welcome To My Life 1998', 'Shui
chi Murakami 1998', 'Shuichi Murakami Welcome To My Life', 'Shuichi Murakami Welcome To My Life 1998']}}

my Python functionr returns the JSON like this:

#format tags
tags = {}
tags["releaseArtist"] = artistsTags 
tags["releaseInfo"] = releaseInfoTags
tags["tracklist"] = tracklistTags
tags["combinations"] = combinationsTags
data = {}
data["tags"] = tags
print('finished python tags look like:')
print(data)
return data

My javascript in an html file receives the tags json data structure like this:

            console.log("ajax request to /my-ajax-test/ was a success !")
            console.log("response = ", response)                                 //encoded output
            console.log("JSON.stringify(response) = ", JSON.stringify(response)) //encoded output
            //console.log("JSON.loads(response) = ", JSON.loads(response))       //no json.loads function
            console.log("JSON.parse(response) = ", JSON.parse(response))         //encoded output

When I print the received json data; all the Japanese characters get encoded like \u9752\u3044\u5c71\u8108:

response =  {"tags": {"releaseArtist": ["Shuichi Murakami", "Nobu Caine", "Electro Keyboard Orchestra", "Mash", "Loser", "Ponta Box", "Mobo Band", "JOQR DJ Girls", "Miro Takebi Trio", "Nobu-Zans", "7 Seven", "Ponta Unit"], "releaseInfo": ["Welcome To My Life", "1998", "Japan", "JVC", "Jazz"], "tracklist": ["Jaco Pastorius Medley = \u30b8\u30e3\u30b3\u30fb\u30d1\u30c8\u30ea\u30a2\u30b9\u30fb\u30e1\u30c9\u30ec\u30fc", "I Want You Back = \u30a2\u30a4\u30fb\u30a6\u30a9\u30f3\u30c8\u30fb\u30e6\u30fc\u30fb\u30d0\u30c3\u30af", "Travelling = \u30c8\u30e9\u30d9\u30ea\u30f3\u30b0", "Ive Got You Under My Skin = \u30a2\u30a4\u30f4\u30fb\u30ac\u30c3\u30c8\u30fb\u30e6\u30fc\u30fb\u30a2\u30f3\u30c0\u30fc\u30fb\u30de\u30a4\u30fb\u30b9\u30ad\u30f3", "\u9752\u3044\u5c71\u8108", "Oh!

So the json data is fine when its in Python, but once it reaches javascript it encodes complex chars, and my attempts to decode it with json.parse / json.loads / json.stringify havent been successfull. Is there a way to ensure that my Javascript always has the same chars as in Python? (For languages with chars like Japan, Middle Eastern, etc...)
