Tsuyu Season in Japan: Embracing the Beauty of Japan’s Rainy Days

What Is Tsuyu? Understanding Japan’s Rainy Season

As spring fades and early signs of summer start to emerge across Japan, the country transitions into its rainy season, called tsuyu in Japanese. The word "tsuyu" literally translates to "plum rain", and refers to the ripening of plum fruits during this time. Typically lasting from late May and lasting until early July or mid-July, tsuyu brings long stretches of steady rainfall and overcast skies. While it may seem like a gloomy time for travel or outdoor activities, the early summer rainy season has its own quiet charm, enlivening gardens, rice fields, and the iconic hydrangeas that bloom in shades of blue and purple throughout the country.

When and Where It Rains: Tsuyu Season Timing Across Japan

The tsuyu season is part of the broader East Asian rainy season and unfolds gradually across Japan, with regional differences in both timing and intensity. In the south, particularly in Okinawa, the rainy season begins as early as early May, a month earlier than in other regions. This early start is due to Okinawa's subtropical climate, where monsoon patterns arrive sooner than in the more temperate northern areas. As the season progresses, it moves northward, affecting mainland Japan, including Kyushu, Shikoku, and Honshu, typically starting in early June and lasting until mid-July.

In contrast, the northern parts of Japan experience a delayed and typically milder rainy season. The Tohoku region generally sees rainfall begin in mid to late June, while Hokkaido and the Ogasawara Islands often escape the tsuyu season altogether or receive only light, sporadic showers. These regional differences mean that while much of Japan is enveloped in cloudy skies and rain during tsuyu, travelers can potentially avoid the heaviest downpours by heading north.

Why the Rainy Season Matters in Japanese Culture

Tsuyu holds deep cultural significance in Japan, closely linked to both agriculture and the arts. Agriculturally, the rainy season is essential for rice cultivation, as the consistent rainfall provides vital water for the rice paddies. Beyond its practical role, tsuyu has inspired numerous works in Japanese literature and art, often evoking a sense of melancholy and introspection. The season's gentle, steady rain is frequently depicted in haiku, symbolizing tranquility and the fleeting nature of life. Tsuyu also features in various seasonal traditions, such as hydrangea viewing, with these flowers in full bloom during the season, and the display of handmade teru teru bozu (sunshine dolls) by children wishing for sunny days.

How Locals Prepare for and Embrace Tsuyu

During the tsuyu period, people in Japan adjust their routines to embrace the rain rather than resist it. Streets become a sea of umbrellas, and homes and businesses are equipped with umbrella stands and plastic bags to keep entrances and spaces dry and tidy. Waterproof shoes and boots become essential, while colorful rain gear adds brightness to otherwise gray days. Supermarkets and department stores stock items for the season, from rainwear to seasonal ingredients, making it easier to navigate and enjoy tsuyu.

At home, preparations for the damp season are equally important. Families take extra steps to air out closets and futons to prevent mold, using dehumidifiers or placing moisture-absorbing products in wardrobes and storage areas. This season also brings the charming tradition of hanging teru teru bozu, small dolls made from cloth or tissue paper. Traditionally crafted by children, these figures are hung outside to wish for clear skies and to drive away the rain.

Tsuyu Weather: What to Expect and How to Dress

When visiting Japan during the tsuyu season, travelers can expect a mix of humid, overcast weather with frequent showers that often feel like a light, persistent drizzle. The temperature is mild, neither too hot nor too cold, but the humidity can make it feel warmer and more uncomfortable. Given the frequent rain and temperature fluctuations, it's best to wear light, breathable, quick-drying clothes that can handle sudden downpours. Waterproof accessories like umbrellas, raincoats, or waterproof shoes are essential to stay dry, while layering with a light sweater or jacket can help stay comfortable as temperatures dip slightly.

Hydrangeas and Tsuyu: A Seasonal Floral Highlight

A highlight of the tsuyu season is the blooming of ajisai, or hydrangeas, which have become an iconic symbol of Japan's rainy period. These vibrant flowers transform temple gardens and public parks into enchanting landscapes, bursting with shades of blue, pink, and violet. Similar to the plum rain that nourishes them, hydrangeas reflect the changing mood of the season, with their colors shifting depending on the soil's acidity. From the hillside gardens of Meigetsuin Temple in Kamakura, also known as the "Hydrangea Temple," to the Shinjuku Gyoen National Garden in Tokyo, there are numerous spots across Japan where visitors can admire these flowers at their peak during tsuyu.
