The Hyperbolic Time Chamber (精神と時の部屋 Seishin to Toki no Heya, lit. "Room of Spirit and Time") is a mysterious dimension that exists outside of Universe 7 but can be accessed from the universe via different doorways. Each chamber has a time-compressed nature, making the flow of time vastly different compared to the flow of time outside of the chamber.
When using the entryway to the Hyperbolic Time Chamber through The Lookout on Earth, one year inside the chamber is the equivalent to one day on the outside. A step over the threshold of the training area brings one immediately into ten times Earth's gravity (the same as that of Planet Vegeta, Planet Zoon, and King Kai's Planet). The air thickness is about a quarter of Earth's and the temperature fluctuates the deeper one goes into the training area.
Variants of Hyperbolic Time Chambers exist in other locations and have different conditions. The Galactic Patrol's entryway allows a person to spend three days' worth inside the chamber over the span of one day. Frieza has access to a variant of the chamber that allowed him to spend ten years' worth of training inside. Whis can create a dimensional space within his staff for similar training purposes, and the Demon Realm Race can summon a "mock" Hyperbolic Time Chamber by using enough power to gather and sustain the chamber.
Description[]
The Hyperbolic Time Chamber is a separate dimension from that of Earth. There is no night or day in the Room, but the surroundings remain a constant bright iridescent white aurora. Its reflective floor is of undefined area, and the Room's boundaries are thought to stretch to infinity in all directions even though it appears to have a definite atmosphere, limiting its size to about that of the Earth. Those talking in the chamber have an echo in their voices akin to when a character thinks a word, rather than says it aloud. However, there are no solid objects other than the entrance for the sound waves to bounce off of.
The Hyperbolic Time Chamber has an entrance at its center, located in a central building with two side wings with housing, food supplies, bathing quarters and sleeping quarters. There are dual giant hourglasses of emerald sand adorning the sides of the building that count down a year within the chamber. A clock on the dome roof of the main part of the building tells the applicable time in the real world. The wooden door entrance is a portal between the Earth and the Hyperbolic Time Chamber and is the only way to travel to the pocket dimension without ripping holes in the dimensional walls.
Training Conditions[]
The Hyperbolic Time Chamber is a place where one can train and get stronger in a short amount of time. There are a number of conditions that make the Time Chamber a perfect place to gain strength quickly. To begin with, the flow of time within the Chamber is compressed. One day of real-world time is equivalent to one year inside the Chamber, or one minute of real time is approximately six hours, five minutes, and 15 seconds in the Chamber.
The gravity in the Hyperbolic Time Chamber living area is described as being "different", though it seems to not be much higher than Earth's gravity of 1g. Alternatively, the gravity of the training area outside the living area is 10g. Gohan's first step over the threshold of the training area brought him to his knees (this does not happen in the Dragon Ball manga, which explains how the gravity could feel "different" in the living area); Trunks also had some difficulty with the gravity, but Goku and Vegeta were both well accustomed to much higher levels of gravity by the time they used the chamber.
The temperature in the training area fluctuates rapidly, ranging between a freezing -40 °F (-40 °C) and a scorching 122 °F (50 °C).
The air pressure is a quarter of Earth's (in the anime, the air is said to grow thinner the deeper one goes into the chamber). Goku explains to Gohan during their visit to the chamber that the air grows increasingly thinner in the recesses beyond the plaza, which can be threatening as the Hyperbolic Time Chamber has no apparent boundaries. The abnormal and inconsistent air pressure makes it difficult to breathe.
The seemingly endless white void can have a potentially maddening effect on a person's mind.
The dilated time combined with the harsh environment essentially allows for someone entering the Hyperbolic Time Chamber to get one year worth of intense training in a single day. Goku has stated that even simply doing nothing in the chamber still takes a massive toll on the body.
The only major drawback is that a person's aging process will correspond to the compressed flow of time inside the chamber, rather than real world time. This means that when someone emerges from the time chamber after a full year of training, they will be a year older and will have lost an entire year of their life in only a single day.
Limits[]
The Chamber can only be used for two days (or two years) by any given person, meaning a person can only enter the chamber twice in their lifetime, assuming they stay for the full year both times. Staying in the chamber for two days straight counts as two uses. If anybody attempts to use the chamber past their 48-hour limit, they will not be able to exit, leaving them trapped in the nothingness and not allowing anyone else to use the outside door.
Furthermore, there are only enough provisions to accommodate two people for one full year. This is commonly misinterpreted as a two-person limit overall, but it should be noted that in the Buu Saga four people in total were inside the chamber.
Improvements[]
The room's door is eventually destroyed, rendering it useless and temporarily trapping several characters inside. The Time Chamber has since been reconstructed by Dende, but with a number of improvements, dubbed the 2nd Hyperbolic Time Chamber.
The two-time limit that a person can enter the Time Chamber has been removed, as Vegeta has used the Time Chamber at total of five times; twice in preparation for fighting against Cell, once with Goku to train for the tournament against Universe 6, once to train for the fight against Goku Black and Future Zamasu, and once to train for the Tournament of Power. Additionally, this new chamber can be used for at least three days (or three years) in a row.
The new room also apparently lacks the old chamber’s weakness of having a destructible door, as Goku states, "No matter how far we take things here, we don't have to worry about destroying anything."[1] This means that people training inside the chamber can go all-out without having to worry about destroying their only exit.
However, the reconstructed Time Chamber is also shown to be capable of being destroyed if one trains intensely enough, as Vegeta ends up destroying it twice in the anime. After Vegeta destroyed it following his training to confront Goku Black and Future Zamasu, Mr. Popo created a rule that Vegeta would be banned from using the Hyperbolic Time Chamber if it was destroyed again, when he was allowed to use the chamber after it was reconstructed again shortly before the Tournament of Power. Humorously, Vegeta ended up destroying it despite the strict warning.
Approximate Time Dilation[]
When using the Earth entry, time passes 365.24 times faster in the Hyperbolic Time Chamber than in the real world, making one day outside the chamber equal to 365.24 days within it (one solar year).
Real World | Time Chamber | Calculation |
1 day | 1 year | 1 day → 365.24d=1y |
1 hour | 15 days, 5 hours, 14 mins and 24 seconds | 1 hour → 365.24h 360h/24(hrs/d)=15d 5h 0.24h×60(min/h)=14.4min 0.4mx60(sec/min) = 24 seconds |
1 minute | 6 hours, 5 minutes and 14.4 seconds | 1 minute → 365.24min 360min/60(mins/h) = 6h 5min 0.24min×60(secs/min)=14.4s |
1 second | 6 minutes and 5.24 seconds | 1 second → 365.24s 360s/60(secs/min) = 6min 5s 0.24s×1000(ms/s)=240ms |
Usage[]
Dragon Ball[]
While never shown, Goku entered the Hyperbolic Time Chamber during his training with Kami in anticipation for the fight against Piccolo in the 23rd World Martial Arts Tournament.[2] While in the chamber, Goku shot up in height.[3] Instead of spending a full year in the chamber, Goku only spent one month, as he could not handle the atmosphere.[4][5]
Dragon Ball Z[]
Imperfect Cell Saga[]
Upon recovering from his heart virus, Goku decided to use the chamber to get an extra boost to handle the androids. He informed his friends about the room, and they were amazed by the prospect. Vegeta and his son's alternate counterpart, Future Trunks, enter the Chamber to train for their attempt to prevent Cell from attaining his Perfect form.[5] Both train as ascended Super Saiyans,[6] and Trunks surpasses his father in brute strength, but has issues with not getting in the way of his father's pride, so Future Trunks hides his power level.[7] Trunks unknowingly makes a mistake by using his time in the Hyperbolic Time Chamber to increase his strength, while sacrificing his speed and dexterity. Vegeta had earlier attained the form, but he quickly learned its weakness earlier.[8]
Perfect Cell Saga[]
Goku and his son, Gohan, enter the Time Chamber in preparation to fight against Cell. Goku tells Gohan that he was here when he was little, meaning that he went into the chamber when he was training during the Piccolo Jr. Saga.[9] While training with his father, Gohan becomes a Super Saiyan.[10] They also developed an optimization technique to stay in the Super Saiyan state for long periods of time in order to eliminate the strain from transforming. This allowed them to save energy for fighting and worked so well they could even sleep while in Super Saiyan form.[8]
Cell Games Saga[]
Goku and Gohan emerge from the Chamber with a heightened control over their Super Saiyan transformation.[11] In an anime-exclusive flashback, Gohan also managed to briefly ascend to a previously unknown form of Super Saiyan before passing out with Goku witnessing this, which ultimately acted as the reason why Goku decided to have Gohan fight Cell, viewing him as being the only one who potentially had any chance at beating Cell.[12]
Piccolo entered the Chamber for meditation and self training,[13] followed by Vegeta[14] and Future Trunks entering again, increasing their power levels even further (although not quite surpassing Goku and Gohan).
Fusion Saga[]
Goten and Trunks briefly use the Time Chamber to prepare for their battle against the horrible Super Buu. Piccolo convinces Buu to wait one hour (roughly two weeks in the Time Chamber) for them to train, and once Buu runs out of patience, Piccolo leads the Majin to the Time Chamber to fight them there. Taking the long way, they spend one minute circling the Lookout (Piccolo deliberately taking the long way to give Goten and Trunks another six hours to train). When Buu and Piccolo enter the Room, Trunks and Goten use the Fusion Dance to become Gotenks. They introduce their Super Ghost Kamikaze Attack and upgrade themselves to Super Saiyan while fused. During the battle Gotenks falsely says he cannot win in hopes of creating a more dramatic victory. Believing the act, Piccolo destroys the Time Chamber's door, trapping everyone in an isolated dimension with no way out (confident the others can wish them back with the Dragon Balls if Buu kills them). Buu cannot stand the thought of being stuck in the Room (mostly because of his fondness towards chocolate, and the lack of it in this dimension). So Buu, in an intense rage, screams at the top of his lungs. The scream is so loud, that it rips a hole leading back to Earth's dimension. Confused and shocked by the phenomenon at first, Buu realizes he could escape through it after it had already shrunk considerably. Buu manages to get through only by deforming his body into a thin rope. The hole closes soon after Buu passes through, and Gotenks and Piccolo fail to make it in time. Gotenks and Piccolo attempt to recreate Buu's mad howl and succeed only after Gotenks transforms into Super Saiyan 3.
The Hyperbolic Time Chamber is rendered non-functional without a door and must be repaired for future use. It can be argued that when Buu destroyed Kami's Lookout in later episodes, the Hyperbolic Time Chamber could have been fully repaired because the Lookout was wished back damage free, whereas in the video game Dragon Ball Z: Shin Budokai, Android 18 mentions that Piccolo fixed the door after the lookout was wished back.
Dragon Ball Super[]
Universe 6 Saga[]
Dende fixes the Time Chamber so that Goku and Vegeta could train in there. Goku and Vegeta train in the room for three years (three days in real time) to prepare for the tournament against Champa's team. They begin sparring in their base forms but turn Super Saiyan Blue after wanting to go all out.
"Future" Trunks Saga[]
After their second loss to Goku Black and Future Zamasu, Vegeta and Goku return to the past, and while Goku learns the Evil Containment Wave, Vegeta decides to spend the time training in the Time Chamber. Bulma tells him that it will take approximately half a day to re-charge the Time Machine, Vegeta prepares to train in the Time Chamber for this duration (roughly six months in the Time Chamber). After he is done training, Vegeta destroys the Time Chamber before returning to the future, creating a huge crater in The Lookout.
Universe Survival Saga[]
Hours before the Tournament of Power, Vegeta decides to train in the reconstructed Time Chamber, and Mr. Popo adverts that he will be banned to use if he destroys it again. This time he trains around for one hour (roughly half a month in the Time Chamber). Vegeta blows it up once again anyway after finishing his training and returns to Capsule Corp.
Galactic Patrol Prisoner Saga[]
During Goku and Vegeta's training in preparation to resume their battle against Moro after having no success to defeating him on New Namek, Goku goes with Merus on another planet to learn how to use Ultra Instinct in hopes of using it as an advantage against Moro to defeat him once their battle resumes while Vegeta is with Irico on Yardrat for Vegeta to learn Spirit Control to use the technique against Moro as well and become stronger. During their training, Merus reveals he knows Ultra Instinct and brings Goku to a room inside a pyramid resembling the hyperbolic time chamber in which 1 day that passes outside of the room is equivalent to 3 days in the room. Because it takes 4 real months outside the room to complete 1 year of training inside of it, he says the main reason for heading inside the room is so that he can unleash his full power without anyone finding out while they continue their training. Now serious, Merus asks Goku if he is ready to continue their training and Goku happily obliges to continue the training.
Granolah the Survivor Saga[]
Although it does not directly appear during this saga, Frieza, after his arrival on Cereal, explains that he utilized a similar area on a planet he had conquered to train for ten years within the room. Both Goku and Vegeta are shocked that such a world existed and helped Frieza. The tyrant states it was because of this that he surpassed Gas despite the latter being empowered by the Cerealian Dragon Balls (as, because it was in a separate dimension, Frieza technically would have been exempt during that time), and also learned a new transformation that was powerful enough to defeat Goku and Vegeta at full power with ease.
Super Dragon Ball Heroes[]
New Space-Time War Saga[]
Shroom, Putine and Salsa transport Goku and Vegeta to the "mock Hyperbolic Time Chamber" so that they can train to fully attain their Perfected Ultra Instinct and Super Saiyan God Super Saiyan (Berserk Controlled) forms respectively. The room brings forth phantoms of those they have encountered before to battle.

In the Butōden series, Legendary Super Warriors, and Budokai series, Battle Stadium D.O.N, Xenoverse series, and Legends, the Hyperbolic Time Chamber is featured as a battle stage.
In Buu's Fury, the chamber is featured when training as Goten and Trunks.
In Sagas, it is used to train Gohan, Future Trunks and Vegeta to transform into Super Saiyans.
In the Budokai Tenkaichi series and Battle of Z, it is a playable battle stage where, for the sake of playability, a transparent wall encloses the plaza (rather than the area surrounding it being infinite as it is in Dragon Ball Z) and the outskirts are a blueish kind of color rather than clear/white.
In Supersonic Warriors 2, it is named Time Chamber where it is a battle stage.
In Burst Limit, the entrance/exit of the Time Chamber makes a cameo in the barren planet stage.
In Dokkan Battle, the Hyperbolic Time Chamber is a training location that boosts the effectiveness of character growth more than any other location.
Trivia[]
- It is said in the Imperfect Cell Saga that only two people can enter the Time Chamber at a time, yet, Goten, Trunks, Piccolo and Super Buu at once are all in it in the Fusion Saga. This is cleared up when it is stated that the chamber only has enough supplies to last two people for an entire year; Goten and Trunks only spent roughly 2 weeks in the chamber, and Piccolo and Buu were only in the chamber for a matter of hours. It is unlikely there is any limit to just how many people can enter the chamber at one time, though without bringing your own supplies or severe rationing, more than two people would have to leave the chamber earlier than one year.
- In Dragon Ball Super, it is shown by Goku and Vegeta that it is possible for at least two people to train inside the chamber for three years (three days outside the chamber), indicating that it is possible to stay longer than one year.
- Considering that Gotenks' fusion could only last for 30 minutes, the fight between Gotenks and Buu inside the Hyperbolic Time Chamber must have taken less than 30 minutes as Gotenks does not unfuse during the fight. If it is assumed that the battle lasts 15 minutes inside the chamber, then from the perspective of the characters outside on the lookout, only 2.5 seconds would have passed between Buu entering the door and the door exploding (from Piccolo destroying it) followed a split-second later by Buu emerging from the portal. Gotenks then takes the time to unfuse and fuse again (mentioned by Piccolo), and since he requires at least one hour between separating and fusing again, this would mean approximately 75 minutes passed inside the Time Chamber between Buu escaping through the portal and Gotenks and Piccolo doing the same. This would mean that outside the chamber, Buu managed to turn everyone into chocolate in less than 12.5 seconds.
- Both Gotenks and Shallot achieved Super Saiyan 3 during their training in the Hyperbolic Time Chamber. Additionally, Gohan first briefly accessed Super Saiyan 2 while training with his father during the Android conflict. Also Vegeta, Future Trunks, and Goku achieved Super Saiyan Second Grade and Super Saiyan Third Grade while training inside the Time Chamber, while Gohan and Goku achieved Super Saiyan Full Power within the chamber as well.
