August 11 marks Mountain Day, the newest national holiday in Japan. The country enacted the first Mountain Day in 2016 for people to enjoy and thank mountains for their blessings. However, the holiday also lands close to the unofficial Obon, or honoring of ancestral spirits, holiday season in Japan. As such, many Japanese people use the holiday to visit their hometowns before the start of Obon. While Mountain Day is a young holiday, the anime and manga worlds are all sending their greetings from the tops of mountains:

The monster synonymous with Mountain Day is Floating Mountain Dragon Yama Tsukami”
Despite being wingless, it floats by storing large amounts of soil inside its body and gases emitted from decaying carcasses… It must smell awful 🤮

Today is Mountain Day🔍
Of all the mountains that appeared in the Pokémon anime, Mount Pericarp, home of Laqua, stands out.
To restore the desolate Laqua to its the Pokémon Paradise, Pagogo (Terapagos), the black Rayquaza, and the white Zygarde (Perfect Form) decided to part ways with Lico, Roy, and Amethio.
Here’s hoping they’ll meet in Laqua again someday…!
