my script

di.xml file:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\Theme\Block\Html\Topmenu" type="Company\Cms\Block\Html\Topmenu" />
</config>

Block file:

<?php

namespace Company\Cms\Block\Html;

class Topmenu extends \Magento\Theme\Block\Html\Topmenu{

    protected function _getHtml(
        \Magento\Framework\Data\Tree\Node $menuTree,
        $childrenWrapClass,
        $limit,
        $colBrakes = []
    ) {
        echo "exxit"; exit;
    }

You need to change below way for your preference,

<?xml version="1.0" encoding="UTF-8"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\Theme\Block\Html\Topmenu" type="Takeuchi\Cms\Block\Html\Topmenu" />
</config>

Replace type="Company\Cms\Block\Html\Topmenu" with type="Takeuchi\Cms\Block\Html\Topmenu"
