Manga to anime changes

• Some scenes added by the anime:

• Ran saying that they just took a break and will leave Kogoro behind
• Conan blushing when Ran tells Kazuha about her dating with Shinichi
• Tetsushin asking if someone lose something
• Heiji wondering if Kogoro ate some weird mushrooms and upset his stomach (refering to the incident in A Cottage Surrounded by Zombies)
• Ran calling Conan after he found a wood shaving

• In the scene where Heiji tries to scare Kazuha about "when the time comes", the anime add an imaginary wolf ear on Heiji.
• In manga, Kogoro found the temple by himself. In anime, Conan is the one who pointed it out first.
• Kentetsu's explanation about the sunset view is expanded compared to manga version. His line about relaxing until evening is also anime addition.

Trivia

• Mount Washio (鷲尾山 ,Washio-san) is a direct reference to Mount Takao (高尾山 ,Takao-san), a mountain in the Tokyo region and popular among tourists and locals to view Mount Fuji on the other side.
  • The mountain temple Shōgaku-ji (昇楽寺 ,Shōgaku-ji) is a pun to the name of Conan's publisher, Shōgakukan (小学館), in the same fashion as the temple with the same name but different kanji (昇岳寺 in the previous case instead of 昇楽寺) from files 559-561. The temple itself does not follow the design of the actual temple on Mount Takao, the Takaosan Yakuō-in (高尾山薬王院), which contains the similar looking kanji "薬". Instead, it follows the design of the Zōjō-ji (増上寺), famous temple in Tokyo. In particular, it is a replica of the Ankoku-den (安国殿), a secondary hall of the temple, which also has its famous relic, a statue of a standing Amida Nyōrai (an iteration of Buddha).
  • The chastisement room has the same proportions as the storage room in Sandei Temple (山泥寺 ,Sandei-ji) from files 108-110.
• The names of the monks are related to iron (鉄 ,tetsu) and monsters (妖怪 ,yōkai) :
  • Tetsushin (哲進) comes from iron and shen (蜃 ,shin), a shapeshifting clam monster ;
  • Kentetsu (賢哲) comes from iron and Xingtian (刑天 ,keiten), a headless monster ;
  • Tontetsu (頓哲) comes from iron and Taotie (饕餮 ,tōtetsu), a monster in Chinese mythology ;
  • Kantetsu (勘哲) comes from iron ;
  • Additionally, Jun Murata (村田 潤) comes from Jun Murata (same kanji), a real-life director for NHK who collaborated with Gosho Aoyama in a 2024 documentary film.
