Tokyo Curiologue

As evening fell on May 30, the banks of the Arakawa River in eastern Tokyo came alive. The streets leading from nearby Kita-Senju Station to the riverbanks were already overflowing with people wrapped in a sense of eager anticipation.  It was a Tokyo night just a little too early to be called true summer, yet beneath the collective gaze of the crowd, the Adachi Fireworks finally began. Tracing its roots back to 1924, the event along the Arakawa River marked its 48th edition in its current format this year. Its greatest appeal lies in the sheer intensity of its “high-density fireworks” display — approximately 13,000 shells launched non-stop within a single hour. Fireworks Blooming Between the Alleys of Shitamachi Strict crowd-control measures surrounded the main riverbank venue for safety reasons. The area was filled with intense excitement, accessible only to those with paid tickets or those who had secured spots hours in advance.  Yet step away from the main site and wander a...

The Grave Hidden in Tokyo’s Financial Center In the heart of Tokyo’s Otemachi district, sleek skyscrapers and corporate headquarters dominate the skyline. This is one of the most powerful financial centers in Japan — a world of glass towers, business suits, and relentless efficiency. But hidden among those modern buildings is something strangely out of place.

According to legend, his severed head rests here. And even today, in the middle of one of the most rational and economically driven places in the world, Tokyo still seems unable to completely ignore him. The Man Who Challenged Kyoto Taira no Masakado was a powerful warrior during the mid-Heian period in the 10th century. At the time, Japan was ruled from Kyoto, while the eastern regions — wha...

Spring in Tokyo brings with it an unusual sight. Look up, and you may notice giant fish-shaped streamers appearing above streets, rivers, and landmarks — colorful carp seemingly swimming through the sky. In the photo above, taken at the foot of Tokyo Tower, dozens of bright fish flutter together in the wind as if they were alive. What are these flying carp, and why do they appear every spring? Carp Swimming Across the Sky They are called koinobori — carp ( koi ) streamers traditionally displayed in Japan on May 5th. Today, May 5th is celebrated nationwide as Children’s Day ( Kodomo no Hi ) , one of Japan’s national holidays. Its origins, however, go back to an older seasonal festival known as Tango no Sekku , which was introduced from China centuries ago. Originally associated with warding off evil spirits, the festival gradually evolved in Japan into a day dedicated to children — especially boys — and prayers for their health, growth, and future success.
