Mitsutani Electric Co., Ltd. (Niigata Prefecture, Representative: Ken Mitsutani) is currently running a crowdfunding campaign for its portable heating gear "HOT PORTER" on Makuake.
Just one week after its launch on April 23, 2026, it garnered over 8 million JPY in support from approximately 500 people, and has now exceeded a cumulative total of 9 million JPY in pledges. It continues to be well-received (project end date: June 29, 2026).
Cumulative pledges exceed 9,000,000 JPY.
In recent years, as preparation for natural disasters such as earthquakes, typhoons, and large-scale power outages has become a social imperative, this product adopts a "phase-free design" that does not require an outlet and can be powered by mobile batteries.
It is attracting attention as a 'disaster preparedness food item' that is useful in a wide range of situations, from daily car camping lunches and outdoor activities to emergency evacuation life.
■ Background: Growing interest in "food preparedness"
According to surveys by the Cabinet Office and the Fire and Disaster Management Agency, while the preparation rate for "food and drinking water" in household disaster stockpiles has improved, the number of households equipped with "means to eat warm meals" remains small.
Based on experiences from the Noto Peninsula Earthquake (2024) and frequent large-scale power outages in recent years, the need to "eat warm food even when the power is out" has rapidly increased.
HOT PORTER is a product that directly addresses this need.
【3 Major Points as a Disaster Preparedness Item】
✔ Can be used with a mobile battery during power outages (USB Type-C power supply compatible)
✔ Heats up to 80°C in 4 minutes. Quickly prepare warm meals and beverages.
✔ Can warm stored foods as they are, such as convenience store bento boxes, retort pouches, and packed rice.
■ Product Features: "Phase-Free" Design Connecting Daily Life and Emergencies
80°C in 4 minutes / Unique Three-Layer Heater
The three-layer structure of carbon planar film heaters (two sides, front and back) + aluminum vapor-deposited PET film + cross-linked foamed polyethylene achieves high power beyond what its compact appearance suggests. It can accommodate bento boxes up to approximately 7cm thick.
2-Way Power Supply (AC100V / Mobile Battery)
It supports not only household outlets but also power supply from large-capacity mobile batteries (USB Type-C to DC conversion cable included). It functions reliably even during evacuations or car camping when power infrastructure is lost.
Size to Fit a Whole Bento Box (approx. 30cm square)
Significantly larger than the previous model (A4 size). It supports practical scenarios such as heating convenience store bento, homemade bento, or two meals simultaneously like packed rice + retort curry. Portability has also been improved with a handle.
3-Stage Temperature Control + Automatic Warming Function
Equipped with 3 modes: bento heating / beverage warming / low-temperature warming. Temperature control by thermistor automatically shifts to warming state after reaching the set temperature, keeping food at the ideal eating temperature.
