laravel db/dbal column comment change

I wanted to change column comment in laravel5.4. So referring to the following URL, tried to implement.

Laravel 5.2 migration comment on column in migration

But migration doesn't change column comment. laravel 5.4 and db/dbal has a problem?

public function up()
{
    Schema::table('search_columns', function (Blueprint $table) {
        $table->string('japanese_name')->comment('internationalized_name');
        $table->renameColumn('japanese_name', 'display_name');
    });
}
