Japan's Activist Stock Names

This post first appeared on 8percentpa.substack.com and is now the #1 most read post on our substack.

Since we started to talk about shareholder activism, the biggest hotbed has been Japan. There are now a few hundred Japanese names owned by activists today. Shareholder activism in Japan started around 2005 when the activist pioneers targeted Japanese broadcasters and food sauces*.

It did not end well.

Foreigners were labelled as arrogant gaijins (i.e. aliens) who didn’t know Japanese ethics and were just vultures, barbarians at the gates, greedy capitalists and enemies of corporate and basically the whole of Japan. Activists were mocked, fined, thrown in jail and chased out of the country.

The Japanese activist pioneer, Murakami Yoshiaki, founder of the eponymous Murakami fund, was imprisoned, taking one for the global activist teams trying to transform corporate Japan during trying times. He now lives in Singapore. Together with his daughter, they are playing key supporting roles in Act II of Shareholder Activism in Japan. 

Fast forward to 2025, things have really changed. 

Activists are no longer the villains. 

Villains today are sleepy management in corporate Japan who couldn’t spell ROE. Okay, they can spell ROE, but probably couldn’t fully appreciate its importance. Certainly, most of them do not know what’s FCF, acronym for Free Cashflow, another key metric for investors. 

That said, you would be surprised how fast Japanese management learn. Once activists show up at their doorstep, you will see FCF on their investor relations’ presentation materials the next quarter. Because their jobs and the company’s independence are now on the line if they cannot win in the court of public opinion. 

Hence we thought it would be interesting and pertinent to write down a list of activist stocks recently and currently “in play”. This would also serve as a good go-to-post should we need to come back to refer to some names. It would also be updated with important new names. New activist campaigns are happening almost weekly. 

Without further ado, here’s the list of the Japan’s activist names in alphabetical order. 

Current List

Alps Alpine (6770 JP, Mkt Cap: USD2.3bn, PER: 15.3x, PBR: 0.7x) : Alps Alpine is a prominent electronics components and car audio manufacturer currently owned by the abovementioned Murakami team (c.17% of outstanding shares) but multiple activists have engaged the company in the past. 

Anicom Holdings (8715 JP, Market Cap: USD440m, PER: 25.5x PBR: 2.3x, EV/EBITDA: 8.8x, Dividend Yield: 1.0%) : Largest pet insurer in Japan invested by Taiyo Pacific Partners for a couple years. Recently, Dalton Investments of Fuji Media fame disclosed a 5% stake in Anicom, causing the stock to jump c.10%. Dalton has signalled that it would made its proposals known. (Updated Sep 2025)

Astellas Pharma (4503 JP, Market Cap: USD20bn, PER: 17.0x PBR: 2.0x, EV/EBITDA: 7.7x, Dividend Yield: 4.7%) : Farallon Capital engaged Astellas with 3% stake and calling for more cost cutting and optimizing R&D. Interestingly, CEO acknowledged the engagement, calling Farallon constructive. Astellas faces a huge patent expiration of its blockbuster prostate cancer drug Xtandi and is probably keen to study more growth strategies, even from activists. (Updated Sep 2025)

Calbee (2229 JP, Market Cap: USD2.7bn, PER: 21.8x, PBR: 1.9x, EV/EBITDA: 8.9x, FCF Yield 3.2%, Dividend Yield 2.0%) : As with Pepsico (engaged by Elliott), Japan’s largest potato chips maker, which is c.21% owned by Pepsico, was similarly engaged by Hong Kong’s Oasis to buck up. Calbee’s earnings have stagnated for 10 years. Calbee is a household name in Japan, but with mere market cap of USD2.7bn and share price having done nothing for a decade, the onus is on management to prove the activist wrong. Oasis has gone up the league table and have engaged bigger boys. This activist might have good ideas up its sleeves to create shareholder value with Calbee. (Updated Sep 2025)

Casio (6952 JP, Mkt Cap: USD1.8bn, PER: 16.2x, PBR: 1.2x) : Casio needs no introduction, its G-shocks, calculators, electronic pianos are ubiquitous but management seemed unable to drive earnings growth and Oasis, yes, the same HK based activist has targeted this company recently (like literally a few days ago in early July 2025). This would be an interesting name to watch for 2025-2026.

Daiichi Life (8750 JP, Mkt Cap: USD28.0bn, PER: 9.2x, PBR: 1.0x) : Daiichi is the only one among four traditional Japanese insurer that is listed and has been targeted by Effissimo, which was the reincarnation of the original Murakami Fund. With 11% stake, Effissimo’s stake is close to USD3bn.

Daihatsu Infinearth (6023 JP, Mkt Cap: USD540mn, PER: 16.4x, PBR: 1.3x, EV/EBITDA: 6.7x, Dividend Yield 1.9%) : Formerly known as Daihatsu Diesel, company was engaged by Kaname Capital which owns 18% of the company. The maker of marine and land-use internal diesel combustion engines share price has rallied sharply since Kaname’s engagement. Most of the engagement details are not public. What we can see in disclosures are i) Imabari is now the largest shareholder (19.6% stake), replacing Daihatsu Kogyo ii) Good english earnings presentation with business details iii) dramatic PBR improvement from 0.4x to current 1.3x! (Updated Oct 2025)

DIC Corp (4631 JP, Mkt Cap: USD2.0bn, PER: 10.5x, PBR: 0.7x, EV/EBITDA: 14.6x, Dividend Yield 3.2%) : Oasis engaged this Japanese fine chemical company making inks, pigments and resins for its art collection in the Kawamura Memorial DIC Museum which rightfully belongs to all shareholders.

eGuarantee (8771 JP, Mkt Cap USD510mn, PER: 19.6x PBR: 3.3x, EV/EBITDA: 10.6x, Dividend Yield: 2.3%) : This is an interesting financial services company that helps companies hedge credit risks, especially invoice non-payments in Japan. Ariake Capital, a constructivist fund launched by ex-Goldman Sachs analyst Katsunori Tanaka, currently owns c.7% of outstanding shares. Responding positively, eGuarantee recently revised its policy to improve shareholder returns. (Updated Oct 2025)

Eiken Chemical (4549 JP, Mkt Cap USD500mn, PER: 22.4x PBR: 1.8x, EV/EBITDA: 11.9x, Dividend Yield: 2.5%) : Japanese diagnostics company with 70% market share in colon cancer screening tests is concurrently engaged by AVI and Dalton (cumulatively owning c.20-25%). Company has responded with new mid term plan and strived to improve shareholder returns. However, with continuing lacklustre earnings (earnings halved from its peak in 2022), it might be privatized should activists find the right buyers. (Updated Oct 2025)

Ezaki Glico (2206 JP, Mkt Cap: USD2.0bn, PER: 25.7x, PBR: 1.1x) : The maker of chocolate Pocky sticks has been targeted by Dalton, the activist that stirred up the media circus in Japan’s media industry (see next entry). Glico was trading below book despite being one of the most iconic Japanese brands with not just Pocky and Pretz but also its Glico Man in Osaka.

Fuji Media (4676 JP, Mkt Cap USD5.5bn, PER: 16.5x, PBR: 0.8x) : This is one of the five TV broadcaster in Japan under fire and the biggest Japan activist play of 2025. Dalton Investments is the main cheerleader now but multiple activists, including the Murakamis have targeted this name.

Gungho Online (3755 JP, Market Cap: USD1.0bn, PER: 16.3x PBR: 1.2x, EV/EBITDA: 3.0x, Dividend Yield: 2.2%) : Once Japan’s famed gaming company founded by Taizo Son (the more famous Son’s younger brother) and creator of megahit Puzzles and Dragons mobile game, the company is being targeted by the aggressive Strategic Capital in Jan 2025. Recently, Strategic raised its stake from 7.5% to 8.5% and seek to remove the CEO and improve transparency on management pay packages can better capital allocation and growth strategies. (Updated Sep 2025)

Heiwa Real Estate (8803 JP, Market Cap: USD1.1bn, PER: 15.6x, PBR: 1.3x, Dividend Yield 3.7%) : Japan’s mid-tier developer owning prime land around the Tokyo Stock Exchange was engaged by LIM advisors, Simplex Asset Management and the Murakami family. The earlier activists were successful in their campaigns selling their stake to Taisei, currently owning c.20%. It is unclear what Murakami family is asking for at this juncture. (Updated Sep 2025)

Hogy Medical (3593 JP, Mkt Cap USD0.7bn, PER: 35.1x, PBR: 1.5x) : Company makes surgical kits in Japan and has been “in play” for some time. In its July 2025 results meeting, Hogy Medical’s management remarked that going private was on cards and stock price went limit up. Otto Oehring knows this name well and has written interesting stuff on Japan.

IG Port (3791 JP, Mkt Cap USD590mn, PER: 35x PBR: 3.7x, EV/EBITDA: 8.7x, FCF Yield: 6.6% Dividend Yield: 1.1%) : Japan’s fabled animation studio behind iconic animation like Ghost In The Shell, which was made into Hollywood movie starring Scarlett Johansson in 2017. The firm appointed Hibiki’s CIO as an independent advisor on its board. (Updated Oct 2025)

Kao (4452 JP, Mkt Cap USD21.1bn, PER: 24.2x, PBR: 3.0x) : Kao is the P&G of Japan without P&G’s high ROEs and valuations. It makes washing detergents, diapers, soaps and shampoos and its brands are well-loved in Asia. Management hasn’t really been sleeping at the wheels but its ROE can definitely be higher than the current 9%. Oasis has started to engage the company as one of its first large / megacap engagement.

Kawasaki Kisen (9107 JP, Mkt Cap USD8.9bn, PER: 9.5x, PBR: 0.8x) : Kawasaki Kisen or K-Line is one of the three Japanese mega-shippers companies that is 35% owned by Effissimo for c.10 years. However, exactly how Effissimo engaged K-Line has remained largely elusive and the one prominent activist action that is public is that one of Effissimo’s key employee became a board director for K-Line.

Keisei Railway (9009 JP, Mkt Cap USD5.4bn, PER: 16.8x, PBR: 1.5x) : Palliser Capital, an upcoming activist, started engaging Keisei Railway to try to catalyze the divestment of Keisei’s crown jewel: its 21% stake in Tokyo Disneyland (Oriental Land 4661 JP) which is worth >JPY1trn and more than Keisei’s own market cap. Insofar, Palliser has not been successful. Similarly, Elliott has engaged Mitsui Fudosan to do the same with its 6% in Oriental Land.

Kobayashi Pharma (4967 JP, Mkt Cap USD2.7bn, PER: 30.4x, PBR: 1.9x) : One of Japan’s well-known OTC drugmaker that also manufactures sanitary products, air fresheners, breath fresheners, pain relief medicine, denture cleaning agents and a slew of household products. Oasis targeted the company after one of their supplement caused 5 confirmed and 75 unconfirmed deaths.

Kyocera (6971 JP, Mkt Cap USD5.4bn, PER: 25.4x, PBR: 0.7x) : Kyoto’s largest electronic components behemoth founded by the legendary Kazuo Inamori which has gone sleepy. Oasis recent launched a campaign to create “A Better Kyocera”.

Kyoto Financial Group (5844 JP, Mkt Cap USD5.2bn, PER: 19.1x, PBR: 0.7x) : Largest regional bank in Kyoto whose holdings of famed Kyoto companies such as Nintendo, Nidec, Murata and Kyocera is more than its own market cap. Silchester, owning an 8.5% stake has been calling for the unwinding of these cross-shareholdings, which is one of the worst use of precious capital.

Lifenet (7157 JP, Mkt Cap USD1.2bn, PER: 23.7x, PBR: 1.8x) : Japan’s first and largest online life insurer held by Effissimo for many years. Constructive engagement coupled with Lifenet’s executive team’s savviness resulted in share price quadrupling over the last couple of years. Effissimo continues to own a big stake.

Lion (4912 JP, Mkt Cap USD2.7bn, PER: 16.4x, PBR: 1.4x) : Japan’s dental care play targeted by Japan Activation Capital, new activist on the block founded by ex-Carlyle senior executive. Lion’s business is great (just look at Colgate’s long-term share price) and yes, it should trade at higher multiples.

Kansai Electric Power (9503 JP, Market Cap: USD16.4bn, PER: 8.2x, PBR: 0.8x, EV/EBITDA: 8.7x, FCF Yield 3.3%, Dividend Yield 2.8%) : Japan’s top utility company is being engaged by Elliott which publicized its 4-5% stake recently. Elliott is calling management to sell non-core assets which it estimated to amount to c.JPY2trn (80% of its market cap) including real estate. The monies could then be used to raise dividends and push share price above 1x PBR. Kansai Electric also has the largest nuclear power footprint in Japan. (Updated Sep 2025)

Keeper Technology (6036 JP, Mkt Cap USD670mn, PER: 20.5x PBR: 5.6x, EV/EBITDA: 12.8x, FCF Yield: 3.9% Dividend Yield: 1.6%) : It was reported that domestic activist, Misaki Capital now owns c.5% of Keeper which is Japan’s largest car waxing company, competitor and interestingly, strategic shareholder to Soft99 (below). Misaki is known to be non-hostile and might perhaps engineer another MBO in this somewhat popular car waxing industry in Japan. Or advise both Keeper and Soft99 to merge perhaps? (Updated Oct 2025)

Mandom (4917 JP, Market Cap: USD650mn, PER: 29.3x, PBR: 1.4x, EV/EBITDA: 9.8x, FCF Yield 8.8%, Dividend Yield 1.9%) : Japan’s leading male cosmetics and hairstyle product maker is being taken private by its own management. Mandom has been engaged by multiple activists, notably Hibiki Path Advisors amongst others and this is management’s bid to get the activists off their backs. Hikibi is fighting for a higher price. This is a portfolio name and we made c.50%. So, Hibiki Path Advisors. Thank you so much! Our analysis on Mandom written in Apr 2025 and updated in Sep 2025.

Meisei Industrial (1976 JP, Market Cap: USD520m, PER: 9.6x PBR: 1.1x, EV/EBITDA: 4.4x, FCF Yield 6.5%, Dividend Yield: 3.7%) : Meisei Industrial specializes in thermal insulation for construction works, an important technology as we need more insulated data centers, more cold chain warehouses in the face of global warming. Dalton related Nippon Active Value Fund has increased its stake to c.10% today and likely targeting privatization given the firm’s cheap valuations. This would be an interesting name to monitor. (Updated Oct 2025)

Mitsui Soko (9302 JP, Mkt Cap USD2.0bn, PER: 28.2x, PBR: 2.5x) : Warehousing subsidiary of Mitsui Group. Japanese newswires got excited when 3D Investment Partners raised its stake from 8% to 9% in July 2025. That said, share price has rallied quite nicely over the past 12 months. Warehouse names in Japan used to be really cheap but at close to 30x PER, perhaps this trade is over. Sumitomo Warehouse (9303 JP) is still cheap though. (Updated Aug 2025)

Money Forward (3994 JP, Mkt Cap USD2.2bn, PER: Negative, PBR: 8.5x) : Japan’s unicorn fintech play listed just a few years ago caught ValueAct’s attention.

Nippon TV (9404 JP, Mkt Cap USD5.5bn, PER: 15.8x, PBR: 0.8x) : Japan’s leading TV broadcaster and owner of Studio Ghibli (whose style is being popularized by OpenAI and used for various purposes). While there is no public record of activist holding the name, it is definitely on many’s radar. This substack has written about Nippon TV and the portfolio is also invested in this name.

Nissan Shatai (7222 JP, Mkt Cap USD980mn, PER: 25.6x, PBR: 0.9x, Dividend Yield: 1.1%) : Nissan’s listed subsidiary making various specially-equipped vehicles, such a, ambulances, children’s school buses, and refrigerator vans.

Omron (6645 JP, Mkt Cap USD5.1bn, PER: 20.5x, PBR: 1.0x) : One of Japan’s top player in factory automation, sensors and controllers, Omron is the newest target of Japan Activation Capital, founded by former Carlyle executive Hiroyuki Otsuka. (Updated in Aug 2025)

Pigeon (7956 JP, Mkt Cap USD1.4bn, PER: 22.0x, PBR: 2.6x) : Pigeon used to be the stock market darling as the China play for premium baby products but has since derated. Japan Activation Capital, which has targeted Lion has also targeted Pigeon. This activist seems to like animals (or rather companies with animal related names).

Ricoh (7752 JP, Mkt Cap USD5.2bn, PER: 13.1x, PBR: 0.7x) : Once the global #3 photocopier alongside iconic names like HP, Fuji Xerox, Canon, Konica Minolta and also Kyocera etc, this stock has languished with bad business decisions and attracted Effissimo is now the #1 shareholder with 21% stake in the company.

Sagami Rubber (5194 JP, Mkt Cap USD69m, PER: 25.4x PBR: 1.0x, EV/EBITDA: 17.2x, FCF Yield: 7.0%, Dividend Yield: 1.1%) : Second largest condom maker in Japan after Okamoto (which we own) targeted by Oasis and Briarwood Chase and the two collectively own c.23% of outstanding shares. Total foreign ownership is c.31%. With its small market cap, this company might be taken private in a flash. That said, there is very little available publicly as to what the activists have in mind or what they want to do with Sagami Rubber. (Updated Sep 2025)

Sanken (6707 JP, Mkt Cap USD1.3bn, PER: 3.9x, PBR: 1.2x) : Targeted by both Oasis and Effissimo, Sanken’s story revolved around its 50% stake in Allegro Microsystem (ALGM US), a power semiconductor company listed on Nasdaq. Sanken’s stake is worth way more than its own market cap and Allegro has initiated a buyback 18% of the stake for USD666m. That said, Sanken still owns 32% of Allegro.

Sapporo (2501 JP, Mkt Cap USD3.7bn, PER: 44.1x, PBR: 3.0x) : Japan’s fourth largest beer company with real estate worth more than its market cap was engaged by activist 3D Investment Partners.

Shibaura Electronics (6957 JP, Market Cap: USD670m, PER: 21.6x PBR: 2.8x, EV/EBITDA: 9.8x, Dividend Yield: 2.3%) : In a rare case of corporate activism, Taiwan’s Yageo made an unsolicited hostile bid for Shibaura Electronics, Japan’s thermistor and sensor maker, earlier this year. This ruffled a lot of feathers and MinebeaMitsumi was brought in as a white knight. After multiple rounds of bids and counterbids, Yageo bid 7,130 yen for Shibaura and looks like Yageo will win. (Updated Sep 2025)

Shiseido (4911 JP, Mkt Cap USD7.1bn, PER: 58.6x, PBR: 1.7x) : IFP, a consumer focused long-only turned activist fund engaged Shiseido, Japan’s #1 cosmetic maker, as its high-profile target in 2025 following a previous failed attempt with Kirin Holdings (beer).

But it was a low-ball bid and Effissimo countered with a higher price which was 66% higher at JPY4,100 per share. Inexplicably, Soft99’s board is arguing that shareholders should accept the lower bid. They might just succeed because the top shareholders are either friends or strategic partners. If so, it will be a blow to activism in Japan. Someone should sue. (Updated Oct 2025)

Square Enix (9684 JP, Mkt Cap USD8.1bn, PER: 37.8x, PBR: 3.5x) : Square Enix is a big name in gaming with valuable IPs such as Final Fantasy and Dragon Quest, featuring the artwork of Toriyama Akira, the author of Dragonball, Japan’s iconic manga and anime of the 1980s and 1990s. 3D Investment Partners have engaged the company to help improve its corporate value.

Sumitomo Realty recently gave up on its poison pill / takeover defense measure, one of the last large cap companies in Japan to do so.

TBS is known for its intriguing dramas but also its ownership of Tokyo Electron and prime land in Akasaka, Central Tokyo. Added together, these assets are worth multiple times its own market cap.

Teijin (3401 JP, Mkt Cap USD1.6bn, PER: 19.0x, PBR: 0.5x) : Teijin is one of Japan’s traditional textile makers which has successfully transformed itself into a chemical conglomerate and carbon fiber manufacturer in the early 2000s. Since then, company ‘s earnings stagnated and Effissimo bought c.10% of Teijin, likely targeting divestment of its non-performing businesses to better focus on its core franchises.

Tokyo Tatemono (8804 JP, Mkt Cap USD3.6bn, PER: 9.3x, PBR: 1.0x) : Tokyo Tatemono is a Tokyo based Tier 2 developer (Tier 1 refers to the top developers like Mitsubishi Estate, Sumitomo Realty and Mitsui Fudosan) with prime land near Tokyo station and is perennially undervalued.
