SQL entries in French/English and Japanese

I have an old SQL4 database and I’m trying to re-upload it to our newly created database on Phpmyadmin. The characters in the tables are latin and japanese. I tried to change those specific columns but the result is still broken characters for the columns I need to display in Japanese.

Here is a screenshot of my problem : https://imgur.com/a/P6GWrnF

As an example, the SQL code looks like this :

CREATE TABLE `bdd` (
  `id` int(11) NOT NULL,
  `ville` varchar(50) NOT NULL DEFAULT '',
  `nom_fr` varchar(80) NOT NULL DEFAULT '',
  `nom_jp` varchar(250) CHARACTER SET sjis NOT NULL DEFAULT '',
  `adr_fr` text NOT NULL,
  `adr_jp` varchar(3000) CHARACTER SET sjis NOT NULL,
  `tel` varchar(20) NOT NULL DEFAULT '0',
  `plan` text NOT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;


INSERT INTO `bdd` (`id`, `ville`, `nom_fr`, `nom_jp`, `adr_fr`, `adr_jp`, `tel`, `plan`) VALUES
(47, 'Tokyo', 'THE KNOT TOKYO Shinjuku', '?U ?m?b?g ?????V?h', '4-31-1 Nishi Shinjuku, Shinjuku Ku, Tokyo', '?????s?V?h???V?h4-31-1', '03-3375-6511', 'the knot.JPG'),
(3546, 'Tokyo', 'HOSHINOYA Tokyo', '???????', '1-9-1 Otemachi, Chiyoda-ku, Tokyo 100-0004', '??100-0004 ?????s?????c??????????9??1', '0570-073-066', 'HOSHINOYA TOKYO.JPG'),

Answer

Problem solved. I didn’t try to change encoding any longer but created a new table with all rows in utf8mb4_unicode_ci and imported the data within this new table.
