What to expect in 2026

“Knockin’ on Locked Door THE STAGE” brings Yugo Aozaki’s popular mystery novel series to the stage for the first time in 2026. The theatrical adaptation combines the original mystery world with a new story written specifically for the stage by Hideya Hamada and directed by Yukihiko Tsutsumi, who also directed the 2023 television drama adaptation. The production is being presented in Tokyo and Osaka from October 6 through November 10, 2026.

At the centre of the story are two unusual detectives, Tori Gotenba and Hisame Katanashi. They operate the detective agency “Knockin’ on Locked Door” and are simultaneously partners and rivals. Their investigative specialties are completely different: Gotenba concentrates on “HOW,” meaning the tricks and mechanisms behind impossible crimes, while Katanashi focuses on “WHY,” examining evidence to uncover motives and reasons.

Tatsuya Ueda plays Gotenba, while Travis Japan’s Noel Kawashima plays Katanashi. The two performers make their first stage appearance together in these roles, bringing the central detective partnership to life through a combination of mystery, investigation and character-driven drama.

The stage story begins when a mysterious envelope arrives at the detectives’ office. Inside are a piece of paper containing a passage from rakugo and a platinum ticket for the new Eternal Liner train. The clues lead Gotenba and Katanashi into a new mystery involving a “moving locked room.” The case eventually connects to the detectives’ own past, giving the production a personal dimension alongside the central investigation.

The production is designed specifically for live theatre, with original stage elements incorporated into the story. Hideya Hamada has stated that the production takes an important episode from the original work as its foundation while adding theatrical highlights, while director Yukihiko Tsutsumi has emphasised the use of large-scale stage mechanisms and digital visual expression.

Venue & performance locations

EX THEATER ARIAKE, Tokyo

The Tokyo performances are held at EX THEATER ARIAKE, located within Tokyo Dream Park in the Ariake district. This is the first venue for the stage production and hosts the longest portion of the 2026 engagement.

The theatre is approximately five minutes on foot from Tokyo Big Sight Station on the Yurikamome Line and approximately nine minutes from Kokusai-Tenjijo Station on the Rinkai Line.

The Ariake location places visitors close to Tokyo Big Sight and the Tokyo waterfront, allowing theatre-goers to combine their visit with sightseeing, shopping and dining around the wider Tokyo Bay area.

ORIX Theater, Osaka

The Osaka performances are held at ORIX Theater in Nishi Ward, Osaka. The venue is centrally located and provides the final setting for the 2026 production.

ORIX Theater is approximately five minutes on foot from Yotsubashi Station Exit 2 and approximately five minutes from Nishiohashi Station Exit 2. It is also around seven minutes from Hommachi Station and about six minutes from Shinsaibashi Station.

Full programme

The detective partnership

The production follows two detectives who share an office but approach mysteries from completely different directions. Gotenba and Katanashi are university seminar classmates, partners and rivals whose complementary skills allow them to tackle cases that ordinary detectives cannot solve.

The HOW detective

Tori Gotenba specialises in the “HOW” of impossible crimes. He examines the mechanisms, tricks and methods that could make seemingly impossible crimes possible. His personality is unconventional and often blunt, and he is willing to disregard ordinary social conventions when pursuing a solution.

The WHY detective

Hisame Katanashi specialises in “WHY.” He examines clues and evidence left behind at crime scenes to determine the motives and reasons behind mysterious situations. His personality is considerably more conventional than Gotenba’s, creating a strong contrast between the two detectives.

The mysterious envelope

The central case begins when an unexplained envelope arrives at the detective agency. It contains a passage from rakugo and a platinum ticket for the Eternal Liner, a new type of train.

The Eternal Liner

The ticket draws the detectives into a mystery aboard the Eternal Liner. The train becomes a “moving locked room,” creating the central investigative challenge of the production.

A mystery connected to the past

As Gotenba and Katanashi investigate the events surrounding the train, the case eventually becomes connected to their own history. This means the mystery develops beyond simply identifying how an incident happened or why it occurred, bringing the detectives themselves into the centre of the investigation.

Featured productions & performers

Tatsuya Ueda as Tori Gotenba

Tatsuya Ueda takes the role of Tori Gotenba. His character is the specialist in impossible-crime mechanisms and the “HOW” side of investigations.

Ueda has extensive experience in both stage and screen acting. His recent theatre work includes “The Mystery Solved at Dinner,” “Hamon Federico” and “Ripley,” while his screen work includes television dramas and films.

Noel Kawashima as Hisame Katanashi

Noel Kawashima of Travis Japan plays Hisame Katanashi. Known within the group for his broad knowledge and intellectual interests, Kawashima takes on the role of the calm and analytical detective who concentrates on motives and reasons.

Kawashima and Ueda are appearing together as co-leads, portraying detectives who maintain a strong level of mutual respect despite their constant differences.

Umi Kawashima

Umi Kawashima appears as Ketsu Ugachi and is part of the principal supporting cast surrounding the central mystery.

Jingi Irie

Jingi Irie plays Mikage Itokiri, another important character within the production’s mystery ensemble.

Kanro Morita

Kanro Morita takes the role of Seitaro Kozubo, contributing to the wider cast of characters connected to the central case.

Shows & performances

“Knockin’ on Locked Door THE STAGE” is structured as a live mystery drama, combining detective investigation with theatrical staging, visual effects and character interaction.

The production is based on Yugo Aozaki’s “Knockin’ on Locked Door” novel series, which has previously been adapted for television. The 2026 stage version is the first theatrical adaptation of the property.

Rather than simply recreating the television drama, the stage production introduces an original story. The case involving the Eternal Liner provides a new mystery for both existing fans and audiences discovering the story through theatre.

The production’s central appeal comes from the contrast between Gotenba and Katanashi. One detective is interested in the mechanics of an impossible crime, while the other searches for its motive. Their investigations therefore approach the same mystery from different directions.

The theatrical production also incorporates music, lighting, sound, video and choreography. The main theme is provided by fox capture plan, with Hideoki Mogi serving as music director, Shotaro Hirayama handling the set design, Hiroshi Misawa the lighting, Takuya Watanabe the sound and Hiroto Takahashi the video.

Director Yukihiko Tsutsumi has described the stage production as a large-scale theatrical version using modern stage mechanisms and digital visual expression. The combination of mystery storytelling and stage technology is intended to create elements that can only be experienced in a live production.

How to get there

Tokyo

EX THEATER ARIAKE is located inside Tokyo Dream Park in Ariake. The easiest public transport options are Tokyo Big Sight Station on the Yurikamome Line and Kokusai-Tenjijo Station on the Rinkai Line.

Tokyo Big Sight Station is approximately five minutes on foot from the theatre, while Kokusai-Tenjijo Station is approximately nine minutes away.

The venue’s location near Tokyo Big Sight makes it easy to combine the performance with other attractions in Ariake and the Tokyo waterfront.

Osaka

ORIX Theater is located in Nishi Ward, Osaka. Yotsubashi Station is approximately five minutes away on foot, while Nishiohashi Station is also approximately five minutes away.

Hommachi Station is approximately seven minutes away and Shinsaibashi Station is approximately six minutes away.

Public transport & parking

Tokyo public transport

The Yurikamome Line provides the most direct rail connection to Tokyo Big Sight Station. Visitors can also use the Rinkai Line to Kokusai-Tenjijo Station. Both stations provide walking access to EX THEATER ARIAKE.

Osaka public transport

ORIX Theater is served by several Osaka Metro stations. Yotsubashi, Nishiohashi, Shinsaibashi and Hommachi are all within walking distance, making the venue accessible from several parts of central Osaka.

Parking

Visitors driving to either performance should check the latest parking arrangements around the venue before travelling. Central Tokyo and Osaka can have heavy traffic and limited parking availability, particularly around busy theatre periods.

Public transportation is generally the more practical option for reaching both venues. Visitors should also allow extra time for walking from the station and entering the theatre.

Accommodation areas

Ariake and Tokyo Bay

Ariake and the wider Tokyo Bay area are convenient for visitors attending the Tokyo performances. These areas provide easy access to EX THEATER ARIAKE and other waterfront attractions.

Odaiba

Odaiba is another practical choice for visitors who want to stay close to Tokyo Dream Park while enjoying shopping, entertainment and waterfront sightseeing.

Ginza and Shimbashi

Visitors wanting a more central Tokyo base can consider Ginza or Shimbashi. Both areas provide extensive hotel choices and convenient rail connections.

Shinsaibashi

For the Osaka performances, Shinsaibashi provides one of the most convenient bases because of its proximity to ORIX Theater and its large selection of restaurants and hotels.

Namba

Namba is useful for visitors combining the performance with wider Osaka sightseeing. It has extensive accommodation, shopping, dining and evening entertainment.

Hommachi

Hommachi provides another convenient Osaka base, particularly for visitors who want easy access to ORIX Theater while remaining close to central Osaka.

Dining & refreshments

There is no separate food festival or dining programme attached to “Knockin’ on Locked Door THE STAGE,” so visitors should plan meals around their selected performance.

In Tokyo, Ariake and the surrounding Tokyo Bay area offer cafés, restaurants and shopping complexes. Visitors attending an afternoon performance can have lunch before arriving or arrange a meal afterwards.

For evening performances, arriving early enough for dinner before the show is recommended. The theatre’s location also allows visitors to continue into other parts of Tokyo after the performance.

In Osaka, ORIX Theater is surrounded by the dining districts of Shinsaibashi, Yotsubashi and Namba. Visitors can choose from Japanese restaurants, casual dining, cafés and international cuisine.

Because performance doors open approximately 45 minutes before the scheduled start time, visitors should leave enough time for dining, transport and theatre entry rather than arriving immediately before curtain time.

Accessibility

The Tokyo schedule identifies October 17, 18 and 19 as performances with audience-support arrangements. Visitors who require these services should review the official support information before attending.

Wheelchair spaces are limited. The official production information asks wheelchair users to purchase an S Seat ticket in advance and contact the relevant performance enquiry service with their seat number. Visitors who use a wheelchair but intend to transfer to their purchased seat are also asked to provide their seat information in advance to help staff prepare for their arrival.

EX THEATER ARIAKE is located on the third floor of Tokyo Dream Park, and the official information specifically recommends allowing sufficient time to reach the venue.

Visitors with accessibility requirements should contact the appropriate organiser before the performance so that available arrangements can be confirmed.

The October 6 performance at 18:00 marks the opening of the Tokyo engagement and the first public performance of the stage adaptation. It is the starting point of the 2026 production.

October 7 offers both a 13:00 and 18:00 performance, providing flexibility for visitors planning a Tokyo theatre day.

October 17 has both afternoon and evening performances and is one of the dates specifically identified by the production as an audience-support performance.

October 24 weekend performances

October 24 features both 13:00 and 18:00 performances and takes place near the end of the Tokyo engagement. It provides two opportunities to see the production on the same Saturday.

Previous year’s highlights

There was no 2025 stage edition of “Knockin’ on Locked Door THE STAGE.” The 2026 production is the first stage adaptation of Yugo Aozaki’s “Knockin’ on Locked Door” series.

The most significant earlier screen adaptation was the 2023 television drama. The official stage production website notes that the drama generated substantial attention, including reaching the top two positions in worldwide trends and surpassing 1.22 million catch-up viewing plays.

The 2026 stage production maintains a direct creative connection with that television version. Yukihiko Tsutsumi returns as director and Hideya Hamada returns as scriptwriter, while the stage adaptation introduces new performers and an original theatrical storyline.

Yugo Aozaki’s original series also has a strong literary background. The official production information notes that the author was nominated for the 171st Naoki Prize and has received multiple literary awards. Aozaki himself describes Gotenba and Katanashi as characters he had long felt were particularly suited to the stage.

The 2026 production therefore represents a new stage chapter rather than a repeat of an earlier theatre run, with the Eternal Liner mystery providing the principal original storyline.
