In 2023, Japan's import of filament lamps of a power not exceeding 200 W and for a voltage exceeding 100 V was valued at approximately 3.0 million USD. The forecast reveals a steady decline from 2024's 2.8021 million USD to 2.0066 million USD by 2028. Year-on-year, this reflects a consistent annual decrease of about 7.2%. The compound annual growth rate (CAGR) over these five years indicates an average annual decline of around 7.2% as well.

Future trends to watch for include:

Technological advancements in lighting alternatives such as LED, which may continue reducing the demand for filament lamps.
Environmental regulations promoting energy-efficient products could further influence import declines in Japan.
Economic factors, including exchange rates and trade policies, may affect future import values.
