==Trivia==
*In "A Crackling Raid Battle!", the song was played mid-episode, but the original version (sung by After the Rain) was used instead of the second version (sung by Takanori Nishikawa and Shō Kiryūin), which was played in the intro at that time.
*The fourth variation of the opening has a few references to the games and past seasons, those being:
**On timestamp 0:11 to 0:12, Ash was being electrocuted by his Pikachu upon receiving it which is a throwback to the first episode of Pokémon: Indigo League titled I Choose You! since it is the 25th anniversary of the anime.
**On timestamp 0:12 to 0:13, Goh noticed Mew's shadow and follows it which is a reference to what inspired Goh to start his own journey.
**On timestamp 0:17 to 0:26, Ash and Goh were travelling to different regions with the order being, Kanto, Johto, Hoenn, Sinnoh, Unova, Kalos, Alola and Galar.
**On timestamp 0:20, Dawn is shown wearing her Platinum outfit.
**On timestamp 0:58, Chloe's Eevee is shown wearing a pin that looks identical to the pin that Serena's Sylveon was wearing when it was still an Eevee in Pokémon X and Pokémon Y.
**On timestamp 1:00, Chloe is shown wearing the outfit that May wears during Pokémon contests in Pokémon Omega Ruby and Pokémon Alpha Sapphire.
*Following his arrest due to charges of attempted sexual assault on October 24, Hidekazu Tanaka's arranger credit was omitted from the song credits, beginning with PJ130. Similarly, the opening and ending credits were removed from the staff listing on the TV Tokyo website on October 25 ,and his name was removed from the official Japanese Pokémon website on October 28.
===Dub differences===
*During the English dub of Pokémon Master Journeys opening animation during the ending credits, the Japanese blue text name "ポケットモンスター" has been edited out in the dub.
*The English ending is a muted version of the Pokémon Shiritori Mew > Zamazenta animation, with the vocal version of the opening theme song "Journey to Your Heart" over it.
