Fertilizer shortage in global supply crunch: May 25: Surging fertilizer prices is causing concern for Japan’s agriculture industry as the country has relied on Russia and Belarus for up to 30 percent of its potassium chloride imports. Imports of the key chemical fertilizer ingredient have halted due to sanctions since March, forcing the country to rely more on Canada for supplies, which has caused a supply crunch as other countries also seek supplies. Even prior to the latest conflict, prices for chemical fertilizers were already on the rise after Chin, which is major producer of ammonium phosphate, tightened controls on its exports of fertilizers in October last year. “According to the agricultural price index published by the Ministry of Agriculture, Forestry and Fisheries on April 27, the retail price of chemical fertilizers as of March was up 11.7 percent year on year.” Source.
Food self sufficiency challenges: May 13: A shortage of agricultural labor and farmland in Japan threatens the country’s prospects for food security In 1960, the East Asian nation reportedly was fully self sufficient for rice, fruits and vegetables, and nearly so for meats; however, in 2021, “while Japan domestically produced 98 percent of rice consumed, the rate was 30 percent for fruits, 76 percent for vegetables, and 16 percent for stock farm products. The rates for other food items were 21 percent for soy beans, 15 percent for wheat, and 11 percent for beef.” Japan’s Ministry of Agriculture, Forestry and Fisheries has set goals to pull the country’s self-sufficiency rate up by increasing the proportion of domestic production of wheat by 40 percent, soy beans by 60 percent, vegetables by 15 percent, and feed by 48 percent, including through the introduction of high-yield and disease-resistant new crop varieties.

The Shizuoka Prefectural Pest Control Station has confirmed cases of sweet potato (Fusarium) root rot for the first time in the prefecture. According to media, citing a Special Bulletin No. 4 issued on December 23, “yellowing and wilting of stems and leaves, blackening of stems and tuberous roots were confirmed in the kansho field in the western part of the prefecture [linked to an ] outbreak in November.” The diagnostic was reportedly confirmed by the Kyushu Okinawa Agricultural Research Center of the Agricultural Research Organization. Cases had previously been reported in the Okinawa Prefecture in 2018, and later in Kagoshima, Miyazaki, Kumamoto, Fukuoka, Nagasaki, and Kochi prefectures. More details in Japanese here.
Gene-edited tomatoes get green light: December 2020:
The Ministry of Health, Labor and Welfare on December 11 approved the production and sale of a gene-edited tomato. The tomato, developed as a cooperation between startup, Sanatech Seed and the University of Tsukuba. According to this Nikkei Asia report, “the fruit features five times the normal amount of GABA, an amino acid linked to lower blood pressure, thanks to tweaks to genes that normally limit GABA production.”. The non trans-genic fruit reportedly took 15 years to develop. Sanatech Seed, which is a startup formed out of the University, will start to sell seedlings for home gardens in the spring of 2021 via online channels, and plans to launch seed sales to large-scale producers in the fall.
Amended Seeds and Seedlings Law strict on IP: December 2020:
A bill to amend Japan’s Seeds and Seedlings Law was passed by the Japanese Diet on December 2. The revised law, now dubbed the Seeds and Seedlings Protection law, as reported here by Japan Times, is expected to take effect in April, and will “allow plant breeders to designate areas where their varieties can be grown and export destinations when they register their species''. The bill which has been liberated by the Japanese legislative branch since earlier this year, was drafted as part of efforts to crack down on the “illicit outflow from the country of cultivars developed through plant breeding.” According to the above article and other detailed reports in the Japanese media, including this report on Yahoo, and this one here as well as this one, unauthorized reproduction of such varieties outside of designated areas and/or in violation of licensing terms could carry hefty prison sentences and fines for violators. The amendment was proposed on the basis of widespread claims of illegal reproduction of Japanese fruits and vegetables in neighboring countries.

Scrutinizing seed coat evolution hypotheses through fossils and genomics
Professor Toshihiro Yamada of Osaka City University has been diligently seeking to shed more light on the evolutionary mechanisms behind the formation of protective seed coatings. According to this report, the professor has considered and scrutinized a number of prevailing hypotheses and theories on the subject, including the telome theory through the work of ate German botanist Dr. Walter M. Chimmelmann as well as other hypotheses related to spore and embryo formation (polysporangiophytes via Dr. Paul Kendrick). The Japanese professor has studied fossils and conducted experiments with relative genes (BEL1, WUS, CNA , PHB , PHV) and may have brought clearer, alternative understanding on the subject, as explained in detail in Japanese here
Invasive wildflower evades Fukushima plant protection eradication, boars blamed
Plant Protection authorities in Fukushima are struggling to eradicate the Cutleaf coneflower (Rudbeckia laciniata), which continues to spread and evade eradication efforts that have been carried out for the past decade. According to this article, the invasive wildflower, native to North America, was introduced as an ornamental plant during the Meija era (circa 1868 to 1912) but rapidly propagated beyond gardens and into the wild, posing a significant threat to many other native wildflower species. Though authorities had successfully destroyed traces of millions of the flowers last year, the species is said to continue to spread. It is hypothesized that thriving wild boar populations looking for earthworms have inadvertently dug up and exposed dormant seeds.
Tracing the origins of the famed ‘Kanazawa Futoshi’ cucumber
An article recounts the story behind the “Kanazawa Futoshi” a popular large variety of cucumber from Kanazawa in Ishikawa Prefecture. The development of the cucumber can be traced back to the early Showa period, when “Kanazawa Setsuna” cucumbers were grown at temple near Kuan. By the Autumn of 1936, a farmer named Toshio Yonebayashi was given seeds of the cucumber, which he distributed to neighboring farmers. Following the war (WW2), there was increased demand for agricultural products and food crops. An industrial workshop was set up in Kuan, and Yonebayashi focused on tomato cultivation and acquired germplasm of thick cucumber varieties from a seedling company in Kyoto.

Seed regulations enacted in 21 prefectures
It has been two years since Japan’s Main Crop Seed law was abolished. The law had established public responsibility for the supply of seeds for major crops such as rice, wheat, barley and soybeans, and thus opened the door for private sector production in these crops. Since the law was established, there has reportedly been a vacuum and thus shortage of seed supply in many areas, prompting the need to enact prefecture level regulations According to a recently published summary by the “Japan Seed Protecting Society,” such seed regulations were enacted in Hokkaido, Miyagi, Yamagata, Ibaraki, Tochigi, Gunma, Saitama, Niigata, Nagano, Toyama, Ishikawa. , Fukui, Aichi, Mie, Gifu, Hyogo, Tottori, Hiroshima, Miyazaki, Kumamoto and Kagoshima. Ordinances have already been enforced in 18 prefectures, but not yet Gunma, Mie and Hiroshima. In addition, the Iwate Prefectural Assembly adopted a petition requesting the establishment of ordinances submitted by the Iwate Food and Agriculture Net in March 2019.

Osaka research: agrobacterial mutagenesis could accelerate gene-editing
Researchers from Osaka University “infected potato with Agrobacterium tumefaciens harboring TALEN-expression vector targeting sterol side chain reductase 2 (SSR2) gene and regenerated shoots without selection. They obtained regenerated lines with disrupted-SSR2 gene and without transgene of the TALEN gene, revealing that their disruption should be caused by transient gene expression. The strategy using transient gene expression by Agrobacterium that we call Agrobacterial mutagenesis, developed here should accelerate the use of genome-editing technology to modify heterozygous plant genomes. The study is reported by ISAAA here, and original study here.
Proposed Seed Bill amendment discussed in Diet but enactment postponed
On 20 May, Japan’s ruling party decided not to put the revised seed bill to a vote — either out of caution, owing to political opposition, or because of requests from civil groups for further deliberation. Seed groups have called for more public discussion before the Diet again considers it. On 19 May, Minister of Agriculture, Forestry and Fisheries Taku Eto said of proposed amendment to the Seed and Seedling Law that the issue was “not yet decided,” adding, however: “Even if the Seed and Seedling Law is amended, nothing will change” in domestic markets. He said revision is necessary because “certain export commodities such as strawberries had leaked overseas owing to self-propagation” and that “registration of varieties cannot stop the outflow under the current legal system.”
Watermelon with micro-sized edible seeds

Proposed seed law amendments seek stronger breeder rights protection
A bill to amend Japan’s Seeds and Seedling Law was submitted to the Diet in April. According to an article in Japanese language, the proposed amendments, which had been approved by Cabinet in March, aim to establish measures to curb the outflow of certain varieties from Japan while providing more IP protection for breeders and innovators. Under the current law it is legal to export registered varieties once the PVP protection period has expired. And while it is already illegal to propagate or sell registered varieties without license, it is reportedly difficult for authorities to track or enforce this aspect, the article notes. Proposed amendments stipulate that owners of protected varieties (such as breeders or institutions) would be able to specify conditions such as the target destination country and cultivation area, with strict penalties imposed for violation of said conditions, including up to 10 years imprisonment and up to 10 million yen fine. Japan has two main categories of sowing seed: general varieties and registered varieties, whereas the general varieties include “conventional” varieties, varieties that have not been registered, and/or varieties whose registration validity period has expired. Another article notes a push by a ‘seed protection committee’ on April 9 for deliberation on the amendment to be postponed due to the coronavirus situation. Another comprehensive report by Yahoo Japan here provides more background on the Seed and Seedling law, and details opposition based on the so called ‘farmers rights’ perspective.
Nagano prefecture seed security regulation in force
Maninichi Japan news reports that new prefecture-level regulations concerning seeds of main crops and traditional vegetables are now in effect. As reported earlier this year, several prefectures started to draft and implement such regulations to clarify prefecture government roles and obligations in seed supply and thus address seed security concerns raised following the abolition in 2018 of the country’s Main Seed Crops law, which no longer obligated the government to ensure staple crop seed supply, and thus promote participation of the private sector in seed production of these crops.
Sakata to launch new mizuna, pak choy varieties
Leading Japanese seed company, Sakata, has circulated details in local media about some of its upcoming planned leafy-green vegetable releases.

Rice farmers diversify into other crops in wake of staple seed law abolition
Miyanichi Press reports on efforts to support rice farmers in the Miyazaki prefecture to diversify cultivation into high-value crops such as vegetables. The news, in Japanese language, cites reports of declining incomes for rice farmers said to linked to the recent abolition of Japan’s Main Crops Seed Law, which effectively ended tax-funded government subsidization for the production and supply of staple crop seeds such as rice, maize and soybean, and thus attempt to attract private-sector investment.
Prefecture-level seed ordinances trending
Sankei News reports that there is an increasing trend of enacting prefecture-level “seed security” ordinances in response to impacts from the abolition of Japan’s Main Crops Seed Law in 2018. According to the article, in Japanese language, such ordinances, which establish regulations, guidelines and seed production subsidization mechanisms, have been enacted in Saitama, Niigata and Hyogo, while similar acts are soon expected to follow in Nagano (as reported in Asahi), Hokkaido, and in Okinawa according to another report by Ronza Web. It was previously reported that the national law was abolished in order to enable the private sector to have a role in seed production of staple crops. In the absence now of the conventional state-subsidized seed supply system, some farmer groups, however, are reportedly struggling to procure quality seeds at competitive prices, which has been reported in Japanese media as one possible reason for rising crop prices.
