The Nagoya Castle keep rebuild

Is the Nagoya Castle keep open in 2026?

No. The keep has been closed since 7 May 2018 and there is no date for reopening. The grounds, the Honmaru Palace and the turrets are open.

The castle's official keep page says that "aging and earthquake resistance problems have forced the closure of the keeps", and that the tower keep cannot be entered. The concrete building still stands, with the golden shachihoko on the roof, and you can walk right up to its stone base.

Some older tour descriptions still promise a climb to the top. They are out of date. Our guide to why the castle keep is closed explains what you can still do inside the walls.

What happened to the 2022 completion target?

It was missed before work could begin. The city signed with the contractor Takenaka in 2017 for completion in December 2022, failed to win approval in 2018, and gave up the date in August 2019.

When the keep shut in 2018, the closure was meant to last about four and a half years, according to Nagoya TV. The schedule depended on the national approval coming in late 2018. It did not, because the city's own expert panel had not signed off on the plan for the stone walls.

No new completion date has replaced it. Some travel sites now write "not before 2032". That is a guess, not an announcement.

Why does the rebuild need the Agency for Cultural Affairs' approval?

Because Nagoya Castle is a Special Historic Site. Demolishing the concrete keep and building a new one changes a protected site, so the national Agency for Cultural Affairs must give permission first.

The agency has published guidance on how castle keeps may be restored. The city's own briefing from early 2026 sums up the two rules it is working to: the rebuild must rest on solid historical evidence, and anything modern, such as fire safety or access equipment, must be removable later without harming the historic structure.

The stone walls are the hard part. The keep base dates from 1610 to 1612, and the agency has been wary of any work that disturbs Edo-period stones. The city's briefing notes that the inner stones of the keep base can only be examined once the concrete keep is gone, and those findings will shape the foundation design. The city's stone wall subcommittee was still meeting in September 2026, its 73rd session.

Nagoya TV quoted Mayor Hirosawa in August 2026 as saying the project was "a little short of halfway", with agency permission the point at which it truly begins.

Will the new wooden keep have a lift?

Probably a small one, but it is not settled. The city backs a compact vertical lift; disability groups want a full elevator to the top floor; the former mayor wants none at all.

Kawamura argued for years that a faithful rebuild should have no elevator. In 2022 the city opened a call for lift technology that could fit a historic frame, and an idea based on lifts used inside ships came forward.

The city's 2026 briefing describes the current design: a car of about 1,350 by 955 mm with a 500 kg capacity, enough for a wheelchair user and a helper or about six people, hung from the beams and fitted between them. Riders would change lifts between floors. A 24-person elevator to the fifth floor was studied and dropped, since it would mean removing about 100 beams and 42 columns. An outside lift tower would stand over 40 m and dig into buried remains.

Not everyone accepts the small lift. Nagoya TV spoke to a wheelchair user who said it cannot carry bed-type wheelchairs or a stretcher. In June 2026 Kawamura asked Hirosawa to build no lifts; Hirosawa kept the small-lift policy. The city held separate hearings with disability groups in August 2026 and, according to News On Japan, aims to present its overall barrier-free plan around February 2027.

How much will the wooden keep cost, and when will it open?

The 2017 estimate was about 50.5 billion yen. No opening date is set, and the city has not published a new budget or schedule.

The cost has not stood still while the project waits. The hinoki already bought is held in storage at roughly 100 million yen a year, Nagoya TV reported, and building costs have climbed since 2017. The mayor has said he will set out the project's direction within the current fiscal year, which ends in March 2027.

Until the agency approves demolition, there is no honest way to put a year on the reopening. We will update this post when an official date exists.

What does the closed keep mean for your visit?

Less than you might fear. The Honmaru Palace is the finest part of the castle and is open, and if you want to climb a keep, Inuyama has an original one within an hour of Nagoya.

Inside the walls you still get the rebuilt palace with its painted sliding doors, three corner turrets that survived 1945, the Ninomaru Garden, the treasure museum and the walls with their carved daimyo crests. Allow two to three hours; our timing guide breaks it down.

For a tower you can climb, the Inuyama Castle day tour includes the ticket to Inuyama's original keep, a National Treasure, then the post towns of Magome and Tsumago. Osaka's concrete keep is a lift-equipped museum; Nagoya vs Osaka compares them.

Climb Inuyama's original keep, then walk the Nakasendo post towns. The castle ticket is included.
