DAJAP is a free fishing-planning tool that brings tide information and marine weather together to help anglers decide when and where to fish. Its website covers 52 fishing locations across Japan, from Hokkaido to Okinawa, with location maps and individual fishing forecasts. Users can check Japan Meteorological Agency tide tables, including high and low tide times, water levels, tide graphs, and forecasts for the coming 12 months. Hourly weather information includes wind direction and speed, maximum gusts, offshore wave height and period, and changes in atmospheric pressure, with warnings for strong winds and high waves.

DAJAP also combines tides, pressure, weather, and lunar conditions into a fishing score from 0 to 100. It identifies the best two-hour fishing window of the day and explains the conditions behind its recommendation. A seven-day calendar lets users compare forecasts and plan around the week ahead. The service also offers a map of fishing spots, fishing terminology, articles, and DAJAP Pro. Its listed data sources include the Japan Meteorological Agency, Open-Meteo, and Astronomy Engine.
