Chiho's shopping notes

Choose one walnut treat, and you will remember why you stopped in Tomi.

Chiho Miyasaka sees Raiden Kurumi no Sato as a food stop on the Asama Sun Line worth more than a rest break. Some days call for handmade soba with walnut dipping sauce; on others, share walnut ohagi in the car or buy vegetables and fruit at the farm shop. Add a brief visit to the Raiden Museum or Unnojuku, and Tomi stays with you through both food and memory.

Eat

Consider handmade soba with walnut dipping sauce, walnut ohagi, or walnut soft serve.

Buy

Look for Shinano walnuts, seasonal vegetables, fruit, Nozawana pickles, and oyaki (stuffed grilled dumplings).

Explore

Add one stop: the Raiden Museum, Unnojuku, the Yunomaru Highlands, or the vineyards.

Highlights

Michi-no-Eki Raiden Kurumi no Sato, on the Asama Sun Line, offers Shinano walnuts grown in Tomi and exhibits connected with Raiden Tameemon, an Edo-period sumo wrestler. The farm shop is known for seasonal vegetables and fruit, walnut sweets, oyaki (stuffed grilled dumplings), and pickles. At the Yunomaru restaurant, handmade soba with walnut dipping sauce, walnut ohagi (sweet rice cakes), walnut soft serve, and set meals using local ingredients are reasons to stop. For a short visit, shop and have a sweet; at lunchtime, eat at the restaurant; with half a day, continue to Unnojuku or the Yunomaru Highlands. Chiho Miyasaka recommends eating and shopping here before exploring more of Tomi.

Why I like it

Reasons to stop here

01

Taste Tomi walnuts in meals, sweets, and gifts

The official site introduces Shinano walnuts as a Tomi specialty and lists handmade soba with walnut dipping sauce, walnut ohagi, and walnut soft serve. Whether you sit down at the restaurant or only visit the farm shop, walnuts give you a starting point.

02

A restaurant open from 7:00 suits a driving day

Yunomaru restaurant is listed as open approximately 7:00–18:00. Near the Asama Sun Line and Joshinetsu Expressway interchanges, it works for an early stop, lunch, or a pause before the drive home.

03

The Raiden Museum adds another side of Tomi

The station's Raiden name comes from Raiden Tameemon, a sumo wrestler associated with the area. See the exhibits and statue while shopping, and the story behind the station's name becomes clearer.

04

Continue to Unnojuku, the Yunomaru Highlands, or the vineyards

The station works for a quick break, but for more of Tomi, add Unnojuku's historic streets, the Yunomaru Highlands' rengé azaleas or snow, or the vineyards toward Villa d'Est.

Route idea

Ways to plan your stop

Spend your time at the station or add somewhere nearby. These ideas help you plan around your companions and the weather.

A short break on the Asama Sun Line

Take home a taste of Tomi in 30 minutes

After parking, use the restroom, then look for Shinano walnuts, vegetables, fruit, and walnut sweets at the farm shop. Even without entering the restaurant, choose a walnut ohagi or other walnut sweet to enjoy in the car or at home.

Parking → restrooms → farm shop → walnut sweets or fruit → departure.

Popular items and seasonal fruit can run low as the day goes on. A morning stop gives you more choice if shopping is your priority.

A stop for a meal

Make handmade soba with walnut sauce the centerpiece of lunch

At Yunomaru restaurant, enjoy locally grown buckwheat flour paired with walnut paste. Companions who want something other than soba can choose set meals, light food, or the cafe, making it easier to settle on a meal.

Restaurant → Raiden Museum → farm shop → cafe or departure.

Inspections and staff training can shorten opening hours. Check official notices if the meal is your main reason for visiting.

A day with a little history and a historic-street walk

Follow the area's names from the Raiden Museum to Unnojuku

See the Raiden Tameemon exhibits at the station, then go to Unnojuku to connect two pieces of Tomi history in a short outing. After shopping and a sweet, a walk past the lattice-fronted houses makes a satisfying adult detour.

Roadside station → Unnojuku → Tanaka Station area if time permits.

Unnojuku is also a residential neighborhood. Follow local signs for photography and parking, and walk quietly.

A highland drive, skiing, or flower season

Prepare before or after visiting the Yunomaru Highlands

For early-summer rengé azaleas, summer alpine plants, or winter skiing, use the station for restrooms, drinks, and a light meal before setting off. Highland weather and temperatures change, so the stop is a useful place to reconsider your plans.

Roadside station → Yunomaru Highlands / shop at the station on the return journey.

Check winter road surfaces; in early summer, check flowering dates and lift operations; during events, expect possible crowds.

A relaxed day of food and shopping

For an adults-only trip, add the vineyards

Start with Tomi walnuts and fruit at the station, then head toward Villa d'Est if time allows. Wine, gardens, and a cafe connect the farm shop's simple pleasures with Tomi's wine culture in one day.

Roadside station → Villa d'Est → Unnojuku or return journey.

Cafe and winery reservations, closing days, and winter closures can change. Drivers should avoid drinking alcohol and focus on shopping.

Family

Visiting with children

Illustrative image — not an on-site photograph

Stars show the editorial recommendation for each age group on a five-point scale. Read the reasons alongside each rating.

Age 1 or younger
★★★☆☆

Convenient for restrooms, a baby changing bed, and a short shopping stop.

Keep meals and shopping brief, with the rest area and car close at hand.

Ages 2–3
★★★☆☆

Walnut soft serve and a brief stop at the children's play area can provide a change of pace.

This is not a destination for large playground equipment. At busy times, Tomi Central Park is another option.

Ages 4–6
★★★★☆

The Raiden statue, museum, sweets, and children's play area can be enjoyed in short segments.

Use the sumo exhibits as a talking point. For a longer visit, add either a park or Unnojuku.

Elementary school age
★★★★☆

Extend the day to the Raiden Museum, Unnojuku, and the Yunomaru Highlands for history and nature.

For a highland trip, check footwear, temperature, and weather, and get a snack and drinks at the station.

Facilities for babies and toddlers

A baby changing bed, family restroom, and accessible restroom are listed.

Outdoor play

The station's children's play area is for a pause. For more active play, head to Tomi Central Park.

Meals

Thinking in terms of soba, set meals, light food, and sweets helps families with children of different ages decide.

Rest

Ideas for a restful stop

  1. 1
    Park and use the restroom first

    Parking, restrooms, and the rest area are listed as available 24 hours a day, making this a useful break on a long drive.

  2. 2
    Make a quick circuit of the farm shop

    Look at seasonal vegetables, fruit, and walnut sweets, choosing heavy items last.

  3. 3
    Add either a meal or the museum

    To avoid an overlong stop, make either walnut-sauce soba or the Raiden Museum the main activity.

Event

Make an event part of your visit

Permanent spaces and dated events are listed separately. Events can change both the atmosphere and crowds; use the official links for details.

Checking event dates.

Spaces used for events

Event plaza

Used for road beautification activities, summer-holiday events, and seasonal events. Parking and the length of a visit may differ on event days.

Farm shop

Seasonal vegetables, fruit, walnuts, grapes, and blueberries make stock arrivals a reason to visit. Plan around sellouts and possible morning crowds.

Yunomaru restaurant

Notices of shortened opening hours may appear. Prioritize official notices if visiting for a meal.

Yunomaru Highlands and Unnojuku

Seasonal events, flowering periods, and historic-street events outside the station can change how you use it.

Local feel

Reasons to return

Practical ideas and things to consider when spending time here.

The farm shop is especially rewarding in the morning

Reviews and visitor accounts often describe stops for fresh vegetables, fruit, and walnut products. If you are shopping, a morning visit generally offers more choice than one after lunch.

Leave alternatives to the restaurant

Soba, set meals, walnut ohagi, the cafe, and the farm shop are close together. If the restaurant is crowded at holiday lunchtime, sweets, shopping, or the museum provide other options.

The Raiden statue and museum are memorable even on a brief stop

Even if you do not follow sumo, the station's name becomes linked to a local figure, leaving a stronger impression of the area than shopping alone.

Check the temperature difference before heading into the highlands

Weather and conditions can change between the station and the Yunomaru Highlands. Adjust clothing, equipment, and road plans for early-summer flowers, summer walks, or winter snow.

For longer children's play, head to a park

The station has a children's play area, but Tomi Central Park is a more practical choice for active play. Combining station meals and shopping with park time works well for families.

Seasonal fruit and walnuts change the shopping selection

The main offerings shift with spring-to-autumn produce, summer blueberries, the autumn walnut harvest, and grape season. Check arrivals and notices before travelling for a particular item.

Before your visit

Things to check before setting out

Opening and closure days, individual businesses and facilities for children or dogs can affect your plans.

  • The shop is listed as open 8:00–18:00; Yunomaru restaurant, 7:00–18:00; Raichan Cafe, approximately 10:00–15:00 (sometimes extended; irregular closing days); and the Raiden Museum, approximately 9:00–18:00. Follow official notices for individual shops and temporary changes.
  • Parking, restrooms, the rest area, the public telephone, and the EV rapid charger are listed as available 24 hours a day.
  • Both the Tobu-Yunomaru and Komoro interchanges are described as about five minutes away via the Asama Sun Line. Check winter road surfaces and weather separately when heading into the highlands.
  • Walnut ohagi, seasonal fruit, and farm-shop vegetables vary through the day. A morning visit is a sensible choice if shopping is your aim.
  • Unnojuku and the Yunomaru Highlands require a further trip from the station. Meals, restrooms, and shopping are easiest to handle before setting off.

What would you like to eat?

A meal, a sweet treat, market shopping or something to take away: choose a focus for the day instead of trying everything at once.

The main lunch choice

Handmade soba with walnut dipping sauce

For the flavors of Tomi-grown buckwheat flour and fragrant walnuts in one dish, make this the focus of a meal stop.

Soba and limited items can sell out; shortened hours and crowds may also affect availability.

A sweet on a short break

Walnut ohagi and walnut soft serve

Even when you do not have time for the restaurant, these offer an immediate taste of the walnut-themed station and an easy treat for companions.

Buy to take home

Shinano walnuts, walnut sweets, and Nozawana pickles

Choose something to open at home or at your lodging, turning a passing break into a Tomi shopping stop.

Seasonal farm-shop produce

Vegetables, fruit, grapes, and blueberries

The morning farm shop is a good place to see what has arrived that day. Seasonal fruit can make shopping a reason to stop in its own right.

Alternatives when it is busy

Raichan Cafe, farm-shop snacks, and the museum

If the restaurant is crowded at holiday lunchtime, leave room in your plans for a snack, shopping, or the Raiden Museum.
