If your Tokyo family trip falls between 1 October 2026 and 22 April 2027, leave Miraikan out of the day's museum visits. The National Museum of Emerging Science and Innovation has announced a whole-museum closure for refurbishment during that period. This is not only a closed gallery or a missing Dome Theater show.
The closure covers the entire museum
Miraikan's official notice dated 24 March 2026 gives the closure as Thursday, 1 October 2026 through Thursday, 22 April 2027 and states "Entire Museum." Its current Japanese admission and online-booking pages repeat the same period. The Dome Theater page also places the closure warning under its programme schedule.
For parents, that means the practical decision comes before planning the journey there. Do not make the museum the indoor anchor of an Odaiba day during these dates, and do not travel there expecting a normal exhibition visit because an old guide still shows opening hours and prices.
General ticket instructions do not override the closure notice
The museum's pages still contain general information about tickets, exhibits and visiting. The Japanese admission page, for example, carries normal hours and admission categories below the closure message. The online-booking page still explains the usual purchase process.
Those standing instructions are not evidence that the building is open during the announced closure. Read the dated closure first. We have not established a public café-only, shop-only or lobby exception, so do not use any of those as a reason to take parents to the closed museum.
The notice says the museum will continue science communication through external events and online information while closed. An off-site event is a different plan: check its actual venue, date, language, registration and access. It is not admission to the museum building.
Use the newer reopening announcement, not "mid-April"
The earlier March 2025 notice described an approximate six-month closure ending in mid-April 2027. The later March 2026 notice gives 22 April as the last closure date. Miraikan's renewal announcement dated 16 September 2026 names Friday, 23 April 2027 for the grand reopening.
Use that newer announced date when sketching a later holiday, but recheck the museum before committing to a visit. A reopening announcement is not a live ticket confirmation for your date. This article has not checked reopening-day inventory or booked anything.
Do not promise the old visit unchanged after reopening
The September announcement describes plans for new exhibitions and dome films, updates to the partner robot Keparan, a renewed children's Curiosity Field and changes to the restaurant, café and shop. It says further details will be provided later.
For a post-reopening family visit, check the actual exhibits, ticket categories, show programme, language support and meal arrangements again. Do not carry an old restaurant menu, film timetable or ticket combination into a new booking as a guarantee. We do not quote future ticket prices or promise particular new services will be ready for a chosen day.
Replace the visit, not the family's rest time
Our suggestion for a trip during the closure is to choose one different outing that genuinely interests the family and check its opening, tickets and arrival route. Do not compensate by filling the museum's old hours with several stops. Leaving time for a seated meal and a hotel break is still a useful choice.
For the wider route, use our Japan trip planning page and mention the travel dates before asking for an Odaiba museum day. This article does not include an alternative attraction ticket, transfer or guaranteed reopening visit.
Questions families ask
Is only part of Miraikan closed?
No. The dated notice says the entire museum is closed from 1 October 2026 through 22 April 2027.
Can the regular opening-hours page prove it is open?
No. The same admission page carries the closure warning. General visiting instructions do not cancel that dated notice.
What reopening date has Miraikan announced?
The 16 September 2026 renewal announcement names Friday, 23 April 2027. Recheck current notices and actual tickets before relying on it.
Will an external event let us into the museum?
Do not assume so. Check the separate event's venue and entry conditions; external events are not proof that the museum building is open.
