Tokyo will see a mild and spring-like week with a mix of sun and clouds. Temperatures stay around 21–26°C (70–79°F) during the day, with cooler mornings ranging from 9–16°C (48–61°F).

This week in Japan, the weather pattern will shift several times due to changing pressure systems. Early in the week, a low-pressure system moves from northern Japan toward the Kuril Islands, while high pressure drifts eastward. As we approach midweek, a ridge of high pressure travels east, followed by a developing trough near the Yellow Sea.

By the weekend, a new low-pressure system is expected to approach from the Korean Peninsula, bringing a front across Japan. This may lead to unsettled conditions, especially later in the week.

Temperatures throughout the week will generally stay mild, hovering around 15–20°C (59–68°F) during the day, with cooler mornings and evenings. You can expect a mix of sunshine, clouds, and some rain—especially toward the weekend.

No typhoon warnings have been issued for the Tokyo area this week.
