According to a new weather forecast from the Joint Typhoon Warning Center (JTWC), a low pressure area is active in the waters south of Japan.
Maximum winds near the center of the depression reached about 55km/h.
Although the area of influence is quite modest, the depression is forming in the remnant strong southern wind zone of storm Nari.
The low pressure is forecast to continue moving north in the coming days and is likely to strengthen into a tropical depression within the next 24 hours.
Meanwhile, Typhoon Nari made landfall in Hokkaido - a large island in the far north of Japan - this morning, July 15.
The storm moved into the Okhotsk Sea at around 7am on July 15 and weakened to an out-of-tropical depression at 9am the same day (local time).
People and tourists in Hokkaido continue to be alert for strong winds, big waves and heavy rain.
The typhoon season in Japan typically lasts from June to October, with peaks in August and September. On average, the country experiences about 20 tropical storms each year, with about 304 of them directly affecting the mainland, causing heavy rain, strong winds, landslides and flooding.
According to the Japan Meteorological Agency (JMA), coastal areas, especially southern and eastern Japan, are often most severely affected during typhoons.
Tourists are advised to closely monitor weather reports, follow evacuation instructions from local authorities and avoid traveling to areas severely affected during the rainy and stormy season.
