Presuming that the player has recently started a New Game, in Pokémon Green. After the player switches the second item: Oak's Parcel with the first Pokémon the values of various RAM addresses will be 'switched'. For example, Professor Oak will be forced to appear outside of Pallet Town and importantly, the map identifier managed by certain warps in the area will start at a constant and deplete every four steps until reaching zero.

The doko kashira door glitch is one of the more notable examples of select bugs, which only exist within the Japanese Pokémon Red and Green. It is perhaps the most well known example in Japan and outside of Japan with the original Youtube video having over two million views. The glitch, amongst other select bugs were documented within the website pokemonbug with URL pokemonbug.oh.land.to and was later referenced by many other (especially Japanese) Pokémon glitch related websites. The phrase "doko kashira" is a transliteration of the Japanese word "どこかしら", literally meaning "where is it?", perhaps in reference to the glitch's arbitrary nature, where without careful planning it is difficult to predict the next location the player is going to arrive.

This select bug has been primarily exploited for the manipulation of the map identifier that another entrance, or exit will take the player to. It has been fairly popular for tool-assisted speedruns of Pokémon Red and Green even outside of Japan because of fast routes allowing the player to warp to the Hall of Fame, usually in under five minutes. However, doko kashira door glitch TAS submissions relating to the Generation I main-series Pokémon games have since been obsoleted by save corruption techniques.

As with all select bugs, the doko kashira door glitch is no longer exploitable in the special edition, Japanese Pokémon Blue because the updated engine of Pokémon Blue no longer keeps the select flag as set (1), if the player has recently pressed the select button on an item and closed the item pack. Additionally, the updated game engine of Japanese Pokémon Blue prevents the possibility of 'switching an item with a Pokémon'. Since the newer localizations of the first generation of main-handheld Pokémon games were based off the game engine of the original Japanese Pokémon Blue, the doko kashira door glitch and any other select bugs are not exploitable in European, NTSC or Korean localizations of the game.

Requirements (to access the Hall of Fame room)

1. A Japanese version of Pokémon Red, or Pokémon Green.
2. Willingess to start a New Game to perform the ideal method; this is optional, however if the player uses his or her existing Save File it is extremely difficult to find another method because this glitch can potentially alter any byte within the game, if some bytes have been written a value other than 00 this could potentially freeze the game if these bytes are shuffled.

An ideal method (to warp to the Hall of Fame) in a short amount of time

One needs to start a New Game if he or she has already delivered Oak's Parcel and recieved the first badge. The following steps presume that the player has started a New Game.

1. Withdraw a Potion from the PC.
2. Walk into the tall grass until Professor Oak brings the player into his lab.
3. Choose any starter Pokémon.
4. After the rival chooses his Pokémon, attempt to leave the lab.
5. Either win or lose to the battle with him and then proceed through the grass again to Viridian City.
6. Enter the Poké Mart and recieve Oak's Parcel.
7. The player should proceed back to Route 1 and enter a battle.
8. Choose the ITEMS option and use the Select button whilst highlighting Oak's Parcel.
9. Select 'Cancel' and then select 'PKMN'.
10. The cursor should still be white, choose the Starter Pokémon to switch it with Oak's Parcel.
11. Check the Starter Pokémon's moves on the 'Fight' screen, to check that essential data has not been altered.
12. If not, RUN from the Pokémon battle and then walk exactly 73 steps, landing the last step in Gary's house in Pallet Town.
13. When performed correctly the player will appear outside of the house where HM02 Fly is normally obtainable. Walk another 5 steps to the right and then move down so that it appears as if the player is attempting to move through the house's ceiling, it is the spot one step north of its right hand corner.
14. The player will appear in the northern section of the Cycling Road House, he or she should walk another 9 steps and aim the last step to be through the exit to the north-east corner.
15. After walking an an extra 44 steps eastwards aim the 45th step to be through the rightmost door of the Celadon Department Store.
16. The player should now be in a glitched version of the Hall of Fame room.
