Ibaraki works as a day trip from Tokyo, but combining Oarai (aquarium & sea), Mito (Kairakuen & Lake Senba), and Tsukuba (Wanwan Land) covers ocean, a famous garden, and a hands-on dog park in two or three days. Late February–March is plum season; Kairakuen gets crowded.

Main sights
1. Aqua World Ibaraki Oarai Aquarium
One of the largest aquariums in the Kanto region. Plan half a day to a full day for sharks, sunfish, deep-sea exhibits, large taxidermy, and shows (sea lions, dolphins, etc.).

- Seaside café (good views when weather cooperates)
2. Hitachinaka Seaside Railway — Minato Line
Local line from JR Katsuta toward Ajigura. Good for harbor-town atmosphere around Oarai / Nakaminato. Pair with the aquarium on a Katsuta → Oarai area route.
3. Kairakuen (Mito)
One of Japan’s three great gardens. Linked to Tokugawa Nariaki; famous nationwide for plum blossoms. Typical visit: Kobuntei, plum groves, and Lake Senba in one walk.
| Topic | Details |
|---|---|
| Location | Mito (bus or taxi from Mito Station on the Joban Line) |
| Admission | Our Mar 2024 ticket: adult ¥300 (areas or rules may differ) |
| Plum season | Usually late Feb–mid-Mar (varies by year) |
| Time needed | 2–4 hours including lakeside |
Near Mito Station: Mitogaku Road signs, Mito Natto Monument, and other easy photo stops.
4. Tsukuba Wanwan Land (dog theme park)
Dog interaction and shows in Tsukuba. Outdoor pens shine on clear days; many families visit. Follow rules and staff instructions—some dogs are marked “not good with children” or “may bite.”
| Topic | Details |
|---|---|
| Location | Tsukuba City, Ibaraki |
| Fees & hours | Check the official site (age tiers, show times) |
| Time needed | Plan half a day |

3-day model route
| Day | Area | Example |

For 1 night / 2 days, stop after Oarai + Mito and save Wanwan Land for another trip.
