The Nikka distillery produces whiskey in the traditional manner, and offers free tours. The distillery is within sight of the main exit from the station, about a three minute walk away. Guided tours are in Japanese. English speakers can tour the distillery with the help of one of the pamphlets printed in English and distributed at the entrance. The distillery makes single malt and blended whiskies. It offers generous free samples and cask-strength samples for a small fee. The store on the distillery's campus sells the locally produced whiskey.
