For mayo lovers of all ages, head to a free factory tour at Kewpie Mayo Terrace and discover what makes Kewpie mayo tick.

What to expect

Get shown around the “factory” (more like a museum) and eat potato salad made from Kewpie mayonnaise, spot the hidden Kewpie mascots, and just have a great time. At the end of the tour, you’ll receive a free souvenir out of several options — we recommend choosing one that includes a miniature Kewpie doll. There’s also a small gift store where you can buy Kewpie food products and themed-goods.


You need to reserve a spot on a tour to get inside Mayo Terrace, luckily these tours are free and often have an English-language option on the day. There are usually three a day from Monday to Friday, but this can vary, so make sure to check the official website.

How to get there

The factory is around a 5-minute walk from Sengawa Station on the Keio Line, around 20 minutes from Shinjuku Station.
