Planetarium Gingaza, Katsushika

Planetarium Gingaza, located within Shoganji Temple in Tokyo's Katsushika ward, represents a unique fusion of Buddhism and astronomy as the world's first planetarium housed inside a Buddhist temple. Established in July 1996, this remarkable attraction emerged from the vision of the temple's 17th chief priest, Kasuga Ryo, who initially installed the facility to explain Buddhist teachings through astronomical concepts. The planetarium quickly evolved into a cultural landmark that opens its doors to the public, offering an unprecedented experience where spirituality meets science under a 7-meter dome that seats 25 visitors.

The temple itself, dating back 400 years, stands out immediately with its unconventional exterior featuring a model space shuttle attached to the building wall, along with whimsical paintings of cats and whales that symbolize various Buddhist concepts. Upon entering the temple grounds, visitors encounter guardian statues unlike any other temple in Japan - a lion representing India's Buddhist traditions and a dinosaur statue, reportedly relocated from a closed museum, both positioned to ward off evil spirits according to temple beliefs.

The planetarium experience consists of a 60-minute program combining digital projections of the cosmos with live narration. Each show features a 30-minute digital planetarium presentation followed by a 15-minute astronomical explanation and a monthly rotating original program that changes themes. What sets this experience apart is the personal touch of chief priest Kasuga himself, who serves as the planetarium director and narrator. A polyglot who speaks Japanese, English, Italian, German, French, and Romanian, Kasuga brings unexpected humor to his presentations, blending astronomical knowledge with Buddhist philosophy and what visitors describe as "monkish jokes." The constellation names are displayed in Japanese, English, Chinese, Korean, and Thai, making the experience accessible to international visitors.

Located at 7-11-30 Tateishi in Katsushika ward, the temple is accessible from both Aoto Station on the Keisei Main Line and Keisei-Tateishi Station, with the journey between these stations taking approximately 4 minutes by train. From Aoto Station, visitors can walk toward Tateishi Station, where the distinctive rocket-adorned building becomes visible, serving as an unmistakable landmark.

The planetarium operates on a reservation-only basis, opening to the public twice monthly on specific dates. Due to its popularity and limited seating capacity, reservations are allocated through a lottery system via the official website, making advance planning essential for prospective visitors. While specific admission fees weren't definitively confirmed in available sources, visitors should prepare cash payment as credit cards are typically not accepted at temple facilities.
