Mito’s reputation as a natto city is about more than flavour; rail travel helped spread it. When the railway reached the area in the late nineteenth century, natto sold at the station could travel to other cities. The local small-bean variety also mixes easily with rice, helping it become closely associated with the region. Today visitors can encounter natto in prepared bowls and dishes or buy it in packages to take home. Near the station, there are two ways to follow that story: sit down for a meal or learn how the food became a local product.
Inside Excel Minami, directly connected to Mito Station, The Natto & Bar MITO RUTSUBO is the dining option. Its menu invites visitors to compare natto from different makers and in different forms, with rice-based meals during the day and drinks in the evening. The shopping centre lists ten seats, cashless-only payment and a lunch-to-dinner break Monday to Saturday; on Sundays and public holidays it serves during the day. It suits rail arrivals and visitors who want to try natto without giving it a whole evening, but check the split schedule and bring a compatible electronic payment method.
For history and shopping, Tengu Natto Sasanuma Goro Shoten is in Sannomaru, about a ten-minute walk from the station’s north exit. The shop sells straw-wrapped, packaged and dried varieties; upstairs, a free exhibition introduces natto history and ways to make it at home. Local tourism information estimates about 30 minutes for the visit. This is a shop with an exhibition space, not a restaurant: available information does not confirm meal service or a served tasting.
Visitors writing about Tengu Natto often appreciate the service, selection and chance to see the exhibition before choosing a souvenir; some mention the aroma of straw and firm beans, while others hoped to find different products. Early feedback for RUTSUBO values comparing styles and its rail-side location, although the branch still has a small review sample. Natto has a distinctive aroma and texture. First-timers can begin with a cooked preparation or mix a small portion before choosing a stronger style.
A straightforward route is lunch at RUTSUBO, a walk to Sannomaru for the exhibition and shop, then a visit to the former Mito Castle grounds or Kairakuen if time allows. In reverse, the shop and museum suit the morning, with a meal back at the station. The exhibition is free, but official listings give different closing times, 5 pm and 5:30 pm; confirm before setting out. This plan separates a natto meal from a cultural visit and lets each stop fit the day.

The Natto & Bar MITO RUTSUBO
Mito Excel Minami 3F, 1-7-31 Miyamachi, Mito, Ibaraki 310-0015, Japan
RUTSUBO occupies a space inside Excel Minami, directly connected to Mito Station, and builds its concept around an ingredient that often divides opinion: natto. Rather than hide its sticky texture, the restaurant makes it the centre of the experience, offering different labels and styles to compare.
There are still few public reviews because the branch opened recently, so its aggregate score should be read cautiously. Early comments appreciate trying straw-wrapped natto, its aroma and the link to related products sold in the station complex; one visitor also comments on the size of the mixing bowl. That practical detail reflects the restaurant’s hands-on idea: mixing natto is part of its flavour and texture, not just a presentation ritual.
