J-Drama Pilgrimage | ビター・ブラッド Bitter Blood (2014) — 西武園ゆうえんち / The Finale Amusement-Park Showdown

The final episode of Fuji TV’s 『ビター・ブラッド』 aired on June 24, 2014. Fuji TV’s official synopsis puts 佐原夏輝 / Natsuki Sahara in an amusement park confronting 貝塚剛久 / Takehisa Kaizuka, who forces him to choose between a bomb planted on the Ferris wheel and rescuing his father 島尾明村 / Akimura Shimao, held in an abandoned building.

The Nationwide Filming Location Guide identifies the exterior used for the fictional 「コスモスターダストアドベンチャー」 as the former 「ミライセンシバトルフィールド」 area at 西武園ゆうえんち / Seibuen Amusement Park in Tokorozawa. This gives the finale a verifiable real-world pilgrimage anchor without pretending that the fictional attraction itself existed as shown.

Seibuen remains an operating amusement park, but the site changed substantially after filming. Seibu Railway records a major renewal and grand reopening on May 19, 2021, while the current park site lists a very different attraction mix. The 2014 battle-field exterior therefore should not be expected to survive in its original form.

The stored coordinate is a present-day park-level pin, not the former attraction footprint, Ferris-wheel bomb point, abandoned-building set, actor location, or camera position. A pilgrimage visit should follow current admission rules and treat the stop as historical site context rather than a preserved set.
