Primary evidence

| Topic | Official source | What it supports | Limit |

|---|---|---|---|

| Date-specific hours | Fukuoka City Science Museum hours notice | The notice states 2026-09-19 through 2026-10-09; Oct 4 is within that coverage. | A notice does not guarantee there will be no later change. Some details are in an image; basic-room hours cross-checked against city regulation. |

| Basic exhibition hours | Fukuoka City regulation | Basic exhibition room 9:30–18:00. | Temporary changes still need checking. |

| Entry price and age | Science Museum admission | Adult ¥510, elementary/junior high ¥200, preschool free with guardian. Estimated family total ¥1,220 for adults and the 10-year-old. | Special exhibitions and dome programs are excluded. |

| Transit | Science Museum access guide | Hakata to Ropponmatsu on Nanakuma Line is approximately 12 minutes; station exit to museum is a very short walk. | Does not verify chosen departure, headway, wait, or delay. Each direction is an estimate with explicit allowances, not a live itinerary. |

| Transit fare | Fukuoka Subway ordinary tickets | 2-zone adult ¥260 / child ¥130; age 6–under 12 is child. Age 1–under 6 is generally free subject to accompanying/guardianship conditions. | The ¥1,300 family total assumes two adults accompany and supervise the five-year-old; verify at travel time. |

| Exhibit content | Science Museum FAQ | Hands-on exhibits include space, environment, life and other themes. | Specific exhibit availability can change. |

| Indoor meal fallback | Science Museum FAQ and Ropponmatsu 421 shop directory | Museum identifies indoor dining/rest spaces with availability caveats; the directory lists Ikkaku Shokudo, 11:00–21:30 (last order 21:00). | Restaurant availability, wait, menu/prices and whether the museum's own room is open are not verified. Lunch remains an estimate. |

Research decisions

- Primary venue: Fukuoka City Science Museum, with lunch in the connected Ropponmatsu 421 complex. Ages 5 and 10 fit hands-on science exhibits without relying on a toddler-specific attraction.

- Viable alternative: Fukuoka Asian Art Museum, South Asia Special Edition (2026-09-19–2027-01-11). Its official guide lists Sunday gallery hours 9:30–18:00 and Wednesday closure; the exhibition page states adults ¥1,000 and junior-high age and younger free. The official access guide says Hakata to Nakasu-Kawabata is about 3 minutes and Exit 6 connects directly to the museum. The children's corner offers Asian picture books. Sources checked 2026-09-28: exhibition, hours and admission, access, children's corner. Estimated station-to-door route is 30 minutes (ride 3, walk 5, wait 8, buffer 14); exact departure and one-way fare search must be rechecked. Food at the museum café is possible per its hours listing, but prices are unknown.

- For the selected Science Museum plan, planetarium programs and special exhibits are out of scope: their date-specific showtimes and availability were not validated. The alternative Asian Art Museum special exhibition is a separate researched candidate with its own published date and age-based fee.

- Two venues pass candidate checks: Science Museum and Fukuoka Asian Art Museum. Marine World Uminonakamichi remains an unresearched comparison lead and is explicitly ineligible.

- Both route estimates start at Hakata Station and end at each venue, never at the fictitious family's home. The Science Museum's official rail estimate is about 12 minutes each way; the Asian Art Museum's is about 3 minutes. Walking, waiting and buffer are planning allowances; no exact train departure is asserted.

- Origin scope: The fictional family lives in Fukuoka, but both candidates' route checks start at Hakata Station. The 45-minute cap excludes home-to-station travel; the route is station-to-venue only.

- Hero art is generated atmosphere, not venue photography. Actual venue information is linked through the official page; no official photos are downloaded or republished.

- The cosmos artwork is only an atmospheric illustration. The selected plan contains no planetarium program or booking.
