The Olivine Lighthouse or Olivine's Lighthouse (Japanese: アサギのとうだいAsagi's Lighthouse, alternatively アサギシティのとうだいAsagi City's Lighthouse), usually shortened in English as simply the Lighthouse (Japanese: とうだいLighthouse), is a location in Johto.
It is also known as the Glitter Lighthouse (Japanese: かがやきのとうだいRadiance Lighthouse), Port Lighthouse (Japanese: みなとのとうだいPort Lighthouse), or in the anime as Shining Lighthouse (with the same Japanese name as the Glitter Lighthouse).
In the Japanese core series games, the name of this area is 「アサギのとうだい」 (Asagi's Lighthouse). This name is seen when the player enters this area, and is also recorded as the meeting location for a Pokémon hatched here. This Japanese name is also often used in the character dialogue. It has a number of English translations:
In English games, this is the name of this area (unlike the Japanese version, the city name is not mentioned). Therefore, when an Egg hatches here, the meeting location will remain as simply "Lighthouse" even though there are also other lighthouses in different regions. Several non-player characters refer to this as just "Lighthouse" in English as well, even though they often use the full name 「アサギのとうだい」 (Asagi's Lighthouse) in the Japanese dialogue.
In Pokémon HeartGold and SoulSilver, a television commercial uses this lowercase common noun with no city name in English: "Come see the lighthouse!" Once again, the Japanese version also uses the longer 「アサギのとうだい」 (Asagi's Lighthouse).
According to the entrance sign, this place is also known as the "Glitter Lighthouse" (Japanese: かがやきのとうだい Radiance Lighthouse), but this name is never mentioned anyone else in the games. In the Japanese version of the anime, the lighthouse is referred by this name, but it was translated as "Shining Lighthouse" in the English dub.
In the core series games, the longer Japanese name 「アサギシティのとうだい」 (Asagi City's Lighthouse) is also found in the game dialogue. However, the equivalent names "Olivine City Lighthouse" or "Olivine City's Lighthouse" are not used anywhere in the English version. In Pokémon HeartGold and SoulSilver, this place is referred to as the "Port Lighthouse" (Japanese: みなとのとうだい Port Lighthouse) in one of the Pokégear calls. In Pokémon Gold & Silver: The Golden Boys, this place is known simply as the "Lighthouse" (Japanese: 灯台 Lighthouse), with the Japanese version written in kanji.
In Generation IV, Gentleman Preston and Lass Connie are actually Trainers from the Gym, and will return there once Amphy has been cured. Also in Generation IV, once the player has spoken to her, Jasmine opens a door for them leading to an elevator that goes from the top floor directly back to the bottom.
The Olivine Lighthouse, known as the "Shining Lighthouse" in the English dub, remains an important landmark and a popular tourist attraction in Olivine City. However, a neighboring electric lighthouse now does most of its work. An Ampharos has historically been the light source, and this tradition continues under Myron's watch.
In Throwing in the Noctowl!, the light of the Shining Lighthouse helped Wings Alexander through the thick fog and avoid crashing his plane, which had Ash's group and Team Rocket aboard, into the Olivine sea cliffs. Janina, Jasmine, and a fully recovered Sparkle waved from the Shining Lighthouse as the plane corrected its course.
In Pokémon Gold, Silver, and Crystal, Jasmine leaves the top floor by walking north, where the only visible exit would be by falling into the hole. In Pokémon HeartGold and SoulSilver, there is an elevator available on the north wall, but Jasmine does not take it; instead, she leaves by walking south and going down the ladder, even though this way is actually a dead end.
Jasmine makes a reference to this lighthouse when she meets the player in Sunyshore City. She says that one of the reasons Sunyshore reminds her of Olivine is because it has a tall lighthouse like her hometown.
