Ibaraki Food Guide: What to Eat and Where to Start

JGO! editorial team — WEBMARKS Inc. (Fujisawa, Kanagawa)

Ibaraki’s regional food includes winter monkfish hotpot, Mito natto dishes, Hitachinaka dried sweet potatoes and locally produced meat, seafood and noodles. For a seasonal meal, compare the published ankou nabe details for restaurants in Oarai. For a snack or gift, look at hoshiimo, or dried sweet potato, in Hitachinaka. Other specialties include Hitachi beef, Okukuji shamo chicken, Hitachi Aki soba, tsukekenchin and stamina ramen.

The official information in this guide was checked on 4 November 2026. Restaurant seasons and hours below are the published details, not a guarantee that a dish will be available on a particular day. Current prices for the monkfish hotpots were not confirmed in the sources reviewed, and Daimaruya’s tourism listings give different Sunday and holiday closing times. Contact the business before making a trip, especially if you are travelling for one particular dish.

A useful way to plan is to choose the food first, then check the restaurant’s own conditions: season, opening hours, reservation guidance, minimum portions and location. The official listings linked below provide a starting point for checking those details. For your wider trip, see our guides to [Japan cash or card], [Japan tipping etiquette] and the [Ibaraki prefecture travel guide].

1. What should you try in Ibaraki?

The right starting dish depends on your travel dates and where you plan to go. Monkfish hotpot is seasonal, with the two Oarai restaurants covered here publishing different season windows. Soboro natto is a traditional Mito dish that combines fermented soybeans with dried radish, while hoshiimo is a practical choice to look for as a snack or packaged take-home food.

For hotpot, check the published season before setting your itinerary: Sudaann lists November through March, while Sansui lists mid-October through late March. These are restaurant-specific periods, so they do not establish availability on a particular date. If you are choosing between the two, also compare their hours, reservation guidance and portion requirements rather than assuming that the same conditions apply at both.

For a food souvenir, the Ibaraki tourism guide identifies Daimaruya as a hoshiimo specialist and also mentions its gelato. If you are more interested in a meal than a packaged product, use the prefectural food guide to identify other regional dishes, then check a named business’s current menu. The available official information identifies specialties but does not provide a single price list covering all restaurants or products.

2. Monkfish hotpot in Oarai

Ankou nabe is a local winter hotpot choice, but the details differ by restaurant. Sudaann describes a miso-based monkfish hotpot made with monkfish liver and asks guests to reserve before visiting. Its published season is November to March, and its current listing gives daytime service from 11:00 to 15:00, with last order at 14:30, and Tuesday as the regular closing day. The restaurant says evening service is suspended and notes that its hours changed on 1 October 2026. Check the Sudaann ankou page for its own guidance and contact the restaurant to confirm arrangements for your date.

Sansui’s tourism-association listing describes monkfish hotpot as available from mid-October to late March, with a minimum order of two portions. It gives the address as 8249 Isohama, Oarai, published hours of 11:00–19:00, Wednesday closure and parking. These are the details in the Oarai tourism association’s Sansui listing; check with the restaurant if you need to confirm current service or reservation arrangements.

The two-portion minimum at Sansui matters if you are travelling alone or if your group wants to order different dishes. Ask the restaurant how it handles your group size and what the hotpot will cost in total before making the journey. The published listings do not provide comparable current prices for both restaurants, so a price comparison cannot be made from the available information.

A practical check before you go is to open the restaurant’s own page, confirm that your date falls within its published season, and contact the business about the dish and booking. For Sansui, use its tourism listing to confirm the address and published parking information; for Sudaann, follow its reservation guidance. Do not treat a listed season as proof of same-day availability, and do not assume that either restaurant’s booking conditions apply to the other.

A video by トラマルch also includes monkfish hotpot in Oarai: watch the video. It can give you another view of the dish, but the restaurant listings are the sources to use for published hours, season and booking guidance. Check those business details directly before travelling.

3. Natto and soboro natto

Natto is made from fermented soybeans, and the MAFF description of Mito natto identifies small soybeans as a characteristic. Soboro natto is a different preparation: it combines natto with dried radish and includes a seasoning process using ingredients such as soy sauce. The ministry identifies central Ibaraki as the main area where the dish was transmitted and describes it as a traditional Mito dish. It also records shoboro natto as an alternative name.

That distinction is useful when reading a menu or looking for local food. “Natto” refers to the fermented soybean food, while “soboro natto” refers to the mixture with dried radish; it is not simply another spelling for a restaurant or shop. The ingredients and seasoning described by MAFF give you a concrete way to identify the dish, but they do not establish that every business uses exactly the same recipe.

For more background, see the MAFF page on soboro natto. If you want to try it during a visit, check the menu of the business you plan to visit rather than assuming that every restaurant serving natto also offers soboro natto. The official information cited here explains the dish and its regional connection, but does not list a specific restaurant, price or serving arrangement.

4. Dried sweet potatoes and cafés in Hitachinaka

Hoshiimo means dried sweet potato. The Ibaraki tourism guide lists Daimaruya as a specialist shop at 18-38 Shakamachi, Hitachinaka, and also mentions gelato there. Its normal published hours are 10:00–17:00, and the listing describes it as open year-round. See the Ibaraki hoshiimo guide for the specialist-shop information.

There is an important qualification if you are planning a Sunday or holiday visit. The hoshiimo guide gives a closing time of 17:30 for those days, while a separate Hitachinaka gourmet listing gives 17:00. Because the official tourism pages disagree, check directly with Daimaruya if you plan to arrive late in the day. The listings do not establish current prices or product-specific shelf life; read the package and ask the shop about the item you choose.

The Hitachinaka tourism page lists Saza Coffee’s main shop at 8-18 Kyoeicho, Hitachinaka, with published hours of 10:00–20:00 and year-round opening. It also introduces Café and Space TOIRO as a place offering a dried-sweet-potato Mont Blanc. The listing is a useful way to compare a coffee stop with a dessert stop, but it does not establish current availability or price for the Mont Blanc.

A short video by @ibaraki_yossy shows a dried-sweet-potato shop and gelato near Nakaminato’s fish market: watch the Instagram Reel. Treat the post as an individual creator’s view rather than a live business-hours notice. If your priority is taking hoshiimo home, check the product’s own label for its storage instructions and expiry date; if your priority is dessert, confirm that the café item is available before setting out for it.

5. Other regional dishes to look for

Ibaraki’s food guide covers more than hotpot, natto and dried sweet potatoes. The prefectural tourism guide describes Hitachi beef as black-haired wagyu from Ibaraki that meets a grade standard of A4 or B4 and above. It also highlights Hitachi no Kagayaki, a prefecture-developed branded meat, and Okukuji shamo, a local chicken speciality. These are useful names to look for when comparing menus, but each restaurant’s own menu determines what is served and at what price.

The prefectural guide also features seafood including whitebait and clams, as well as monkfish. Other listed dishes include Hitachi Aki soba, tsukekenchin and stamina ramen. You can use the Ibaraki tourism guide to major foods as a reference for the regional names, then check the business you plan to visit for its particular ingredients and serving details. A regional dish name alone does not establish that a specific restaurant serves it year-round.

Creator posts can provide additional examples of foods associated with particular areas. A JA Group Ibaraki video follows a melon harvest in Hokota (watch the video). Several posts show chestnut sweets in Kasama, including posts by @marondo_kasama, @kurinoie.sweets and @ibaraki_select. These posts are snapshots, not confirmation of a shop’s current stock, opening hours or prices.

A further short video by @ibaraki_yossy shows a local stamina ramen dish (watch the Reel). If a named dish is the reason for your visit, check the restaurant’s menu and ask about the ingredients that matter to you. The official information reviewed here does not establish the menu, price or seasonal availability of a particular stamina ramen, soba or meat dish at an individual business.

When comparing meals for a group, keep the number of people, the number of portions and the stated price together. For example, Sansui’s published two-portion minimum is a condition for that listed hotpot, not a rule for every monkfish restaurant. A menu quote for Hitachi beef or another specialty should likewise be checked with the business serving it. A dish price is not automatically a full trip budget, and the sources cited here do not provide transport costs or a complete meal total.

6. See local creators’ posts

The creator posts linked in this guide show individual views of Ibaraki food: monkfish hotpot in Oarai, dried sweet potatoes and gelato near Nakaminato, melon harvesting in Hokota, chestnut sweets in Kasama and stamina ramen. They are useful for seeing examples of dishes and food settings that a short official listing may not show. The posts are in Japanese, so captions and details may require translation.

Use social posts as inspiration rather than as a substitute for checking a business. A creator’s video or photograph does not confirm current prices, opening hours, seasonal menus, stock or reservation conditions. Before travelling for an item shown in a post, check the business directly or use the relevant official tourism listing where one is provided.

7. Ibaraki food guide FAQ

These answers distinguish the published information from details that need to be checked with a restaurant or shop. Seasonal windows and listing hours are useful planning references, but they do not guarantee a service on a particular date. Where official listings differ or do not give a price, the answer says so rather than estimating.

When is monkfish hotpot available in Oarai?

The published seasons differ by restaurant: Sudaann lists November to March, while Sansui lists mid-October to late March. These windows describe each restaurant’s published season and do not guarantee that hotpot will be available on your chosen date. Contact the restaurant before travelling, and remember that Sudaann asks guests to reserve before visiting.

What is soboro natto?

Soboro natto is a traditional Mito dish combining natto with dried radish and a seasoning process that can include soy sauce. MAFF identifies central Ibaraki as its main area of transmission and records shoboro natto as another name. The ministry also describes small soybeans as a characteristic of Mito natto; for the dish’s ingredients and regional background, see the MAFF explanation.

Where can I look for hoshiimo in Hitachinaka?

Ibaraki tourism lists Daimaruya, a dried-sweet-potato specialist at 18-38 Shakamachi, Hitachinaka, and also mentions its gelato. Its normal published hours are 10:00–17:00, and it is described as open year-round. The tourism pages disagree about Sunday and holiday closing time, so confirm directly if you plan to visit late.

Does Sansui serve monkfish hotpot for one person?

The Oarai tourism-association listing says Sansui’s hotpot is available from a minimum of two portions. It does not explain how the restaurant handles a solo traveller or whether a different arrangement is possible. Contact Sansui to ask about your group size and the total cost before planning your visit.

Are current prices listed for the hotpot or hoshiimo?

The restaurant listings reviewed for this guide do not provide a confirmed current price comparison for Sudaann and Sansui’s monkfish hotpots. The official hoshiimo information also does not confirm prices or shelf life for individual Daimaruya products. Ask the restaurant or shop for current details, and use the product label for the specific package’s storage instructions and expiry date.
