富士山河口湖ピアノフェスティバル2026 辻󠄀井伸行 清水和音 児玉桃 三浦文彰 松井秀太郎 スーパーソリストとオーケストラ 夢の競演— Okamoto Riku Yamanashi tickets

Kawaguchiko Stellar Theater is a semi-open-air music venue located in Fujikawaguchiko Town, Yamanashi Prefecture, at the northern base of Mount Fuji and near Lake Kawaguchi. Operated by the local municipality, this amphitheater-style venue is designed to integrate with its natural surroundings, offering views of Mount Fuji from parts of the audience area. The theater features a fan-shaped, tiered seating arrangement with a total capacity of approximately 2,000, all of which are fixed seats that provide clear sightlines to the stage. Primarily hosting concerts, festivals, and cultural events during the warmer months, its partially open structure means acoustic performance is tailored to the environment and can be influenced by weather conditions. The venue is distinguished by its scenic backdrop, which contributes to a unique atmosphere for performances.
