Koukokuji Buddhist Temple, nestled in a quiet part of Shinjuku, Tokyo, is a compelling site that bridges traditional Japanese spiritual practices with cutting-edge technology. While it functions as a serene temple with ancient ginkgo trees and traditional cemeteries, its most striking feature is the Ruriden columbarium. This modern facility houses over 2,000 small altars, each containing the ashes of the deceased beneath a crystal Buddha statue that illuminates with LED lights, offering a unique and futuristic approach to memorialization.
Visitors consistently praise the columbarium's innovative design and the mesmerizing display of the illuminated Buddhas. The experience of seeing the LED lights change colors and create various patterns is often described as beautiful and thought-provoking. Many find the blend of the sacred with the technological to be a powerful and moving experience. The ancient ginkgo trees, estimated to be over 300 years old, also receive frequent mention for their impressive size and historical significance, having survived major historical events.
To fully appreciate the columbarium, visitors should plan to spend at least fifteen minutes inside, as the LED display evolves over time, revealing different colors and designs. While the doors to the columbarium are generally open, activating the Buddha lights requires a smart card. A caretaker is usually on hand and happy to assist; simply ask them to swipe their card. If you wish to see a specific Buddha light up without having a relative there, you can type "コウコ" (ko-u-ko) on the provided tablet, and "幸國寺" (Koukokuji) will appear, allowing you to initiate the illumination. The best time to visit is during daylight hours to also enjoy the temple grounds and ginkgo trees.
Koukokuji Temple is easily accessible, located an easy 10-minute walk from the West exit of Ushigome-Yanagicho Station on the Oedo Line. This makes it convenient for those relying on Tokyo's extensive public transportation network. No specific parking information is available, suggesting public transport is the recommended method of arrival.
Common complaints are rare, but some visitors might find the experience brief if they only focus on the columbarium without exploring the rest of the temple grounds. To mitigate this, take time to walk through the outer buildings, past the torii gates, and explore the main shrine, the temple bell, and the small cemeteries, including the area with the ancient ginkgo trees.
