1 Best Sight in Shikoku, Japan

Hakata Salt Company Omishima Factory

For centuries Hakata Island has been famous for its high-quality salt, and the Hakata Salt Company offers daily, free, self-guided tours of its factory on Omishima Island that take about 30 minutes to complete, though they were suspended during the pandemic and expected to resume sometime in 2022. As you stroll along a marked visitor’s path through the factory, you’ll see workers turn seawater into table salt, package it, and ship it all over Japan. There’s also plenty of information, though most only in Japanese, about the history of salt. If the factory touring has you craving something salty, try the salt ice cream sold on-site. If that’s not enough, you can also take a dip in the salt baths at the Mare Grassia bath complex next door.
