Japan Engine Conducts Final Tests on Ammonia Marine Engine

Japan Engine Corporation, a manufacturer of marine engines, says it has begun final testing of a new engine that uses a fuel mixture of ammonia and heavy fuel oil. The testing involves running the engine alone in a factory to confirm safety and to check for abnormal behavior. Testing is expected to be completed by September, with production planned to begin in October.

The large, low-speed marine engine developed by the company can burn up to 95% ammonia (by heat ratio) mixed with heavy fuel oil. The engine used in this trial will be installed in an ammonia carrier ship currently under development with Nippon Yusen and others. The ship is expected to be completed in fiscal 2026.

KG Motors To Mass-Produce Ultra-Compact EVs

Akihiro Komuro

KG Motors, which manufactures and sells the ultra-compact “mibot” EV, is moving toward mass production of the units. It will start mass production in October 2025 at an assembly plant it has built near its headquarters. The company plans to produce 300 units in FY2025, 3,000 units in FY2026, and 10,000 units in FY2027.

The mibot is a one-person vehicle designed for short-distance travel, with a range of 100 kilometers per charge. The planned price at the time of mass production is 1.1 million yen ($7,700 USD), including consumption tax.

The assembly plant in Higashi Hiroshima City consists of a single production line with a main line of seven processes and a subline of four processes. Since there are only a few parts, the number of processes is less than that of a normal automobile production line.

Honda To Launch Electric Motorcycles in Vietnam

Akihiro Komuro

Honda plans to launch an electric motorcycle in Vietnam this month. The suggested retail price is less than 29 million VND (about $1183) without battery. The company is targeting the younger generation, who often use motorcycles to commute to school.

The name of the motorcycle to be sold is “ICON e:”. It will be manufactured at the company’s Binh Phuoc plant in northern Vietnam and will initially be sold through authorized dealers in seven provinces and cities. The maximum speed is 48 km/h, and it takes about 8 hours to charge the battery from zero to full. The maximum distance that can be traveled on a full charge is 71 kilometers. Because it does not require a driver’s license, which can be obtained at age 18, it is expected to be used by high school students on their way to school.

US Tariffs Could Hurt Japan GDP

Akihiro Komuro

On April 12, as I write this, things are still in flux. There is a lot of media coverage every day, with reports on the tariffs reaching almost hysterical levels. The reciprocal tariff rate for Japan announced by the U.S. is 24%, which is an unexpectedly high level given the past relationship between the two countries.

As a result, Japan’s real GDP is expected to fall by about 0.6% in the short term (2025) and 1.8% in the medium term (2029). This will have a huge impact on Japan, which has maintained a growth rate of around 3% per year. It has been reported that Japan is currently negotiating with the Trump administration, but it is doubtful whether the current Japanese government will be able to negotiate effectively with the US. We will see whether the terms will be reconsidered after the negotiations in the future.

I would just like to point out one thing: President Trump talks about Japan’s failure to buy American cars as unfair and negligent, but this is a clear mistake. It is true that American cars do not sell well in Japan. GM is the only company with a formal dealer network in Japan, and it is even hard to find GM dealer shops in Japan. Chrysler pulled out in 2018 and Ford in 2016.

Kubota Plans Tractor Plant in India, Doubling Production

Akihiro Komuro

Kubota plans to build a tractor factory in India, open that will be operational by 2030. The investment is expected to be in the tens of billions of yen. The annual production volume will be increased to approximately 240,000 units, double the current volume.

India accounts for about half of the global tractor market in terms of volume, but Kubota’s market share in the country is only about 25%. The company aims to increase sales by developing new products in cooperation with the local manufacturer it has acquired.

Currently, it produces about 120,000 units a year at three factories, including Escorts, which it acquired in April 2022 for about $953,020,000 USD (140 billion yen). Its production capacity is 170,000 to 180,000 units, but it is expected to fall short of that in the next five years.

Kanadevia To Build Plant for Hydrogen Equipment

Akihiro Komuro

Kanadevia (formerly Hitachi Zosen) said it plans to build the first mass-production plant for water electrolysis equipment, which produces hydrogen by electrolyzing water, in Yamanashi Prefecture.

A company announcement said, “We want to develop this as an important production base that contributes to the realization of a hydrogen society. The company will invest approximately 8 billion yen ($52,000,000 USD) to build a mass production plant for water electrolysis equipment with an annual production capacity of 1 gigawatt (157,000 tons of hydrogen produced).

Construction is scheduled to begin about June 2026, with completion and operation by the end of fiscal 2028. The company plans to position this as a domestic mother plant, and in the future, it envisions gradually expanding its hydrogen production equipment manufacturing bases both in Japan and overseas.
