October 2026 marks the historic 30th Anniversary of the Pokémon Trading Card Game. The hype reached a fever pitch following the February 2026 “Pokémon Presents,” where a global simultaneous release of commemorative products was announced.

Historically, milestone anniversaries have triggered massive market shifts. Based on recent data from SNKRDUNK, we’ve ranked the top Japanese sealed boxes with the highest growth rates over the last three months.

If you’re looking to add some “Holy Grails” to your collection before the 30th-anniversary madness truly begins, here is what the Japanese market is craving.

Market Trends Chart

Price In January	Current Price	Increase Rate
¥29,993 JPY	¥68,500 JPY	128.4%

The “Fusion” battle style once dominated the meta, but the real draw here is the Mew VMAX Alternate Art. This card, featuring a Gigantamax Mew playing innocently in the sky, is a certified masterpiece currently trading for around 130,000 JPY. With the 30th-anniversary teaser featuring Mew and Mewtwo, fans are panic-buying this long-out-of-print box to secure a piece of Mew’s history.

#2. Scarlet & Violet Enhanced Expansion Pack “pokemon card 151” Box

Trend Market Chart

Price In January	Current Price	Increase Rate
¥32,458 JPY	¥72,645 JPY	123.8%

This set is the ultimate “Gen 1” tribute, featuring all the original 151 Pokémon. It includes the highly sought-after “Master Ball” mirror holos, which are unique to the Japanese release. Rumors of it being permanently out of print (discontinued), combined with the 30th-anniversary focus on the franchise’s roots, have sent demand into the stratosphere.

#3. Sun & Moon Enhanced Expansion Pack, Jizzy End Box

Trend Market Chart

Price In January	Current Price	Increase Rate
¥50,000 JPY	¥109,998 JPY	120%

A classic from the Sun & Moon era. This set popularized the TAG TEAM GX mechanic. Even lower-tier cards from this era are seeing a “PSA 10 premium,” where high-grade slabs fetch astronomical prices. As sealed supply dwindles, investors are pivoting to these older, iconic sets as a hedge against inflation.

#4. MEGA Expansion Pack “Inferno X” Box

Trend Market Chart

Price In January	Current Price	Increase Rate
¥13,046 JPY	¥28,490 JPY	118.4%

Featuring the fan-favorite Mega Charizard X ex in its black-and-blue flame glory. Charizard is the undisputed king of TCG investing. With multiple high-rarity versions like SAR (Special Illustration Rare) and the new MUR, this box is a magnet for “Zard hunters” worldwide.

#5. Scarlet & Violet Expansion Pack “White Flare” Box

Trend Market Chart

Price In January	Current Price	Increase Rate
¥10,215 JPY	¥21,549 JPY	111%

This set introduced the BWR (B-White Rare), a stunning white-themed textured rarity. The Reshiram ex BWR is the crown jewel here. Since this specific rarity is exclusive to this era, collectors view it as a “once-in-a-lifetime” printing style, driving up the box’s long-term value.

#6. Scarlet & Violet Expansion Pack “Supercharged Breaker / Super Electric Breaker” Box

Market Trend Chart

Price In January	Current Price	Increase Rate
¥20,148 JPY	¥39,550 JPY	96.3%

The face of the franchise, Pikachu ex (Stellar Tera), graces this box. The SAR featuring Pikachu in a sun-drenched meadow is a visual triumph. Given Pikachu’s legendary status, any box featuring a “top-tier” Pikachu card is a safe bet for consistent growth.

#7. Scarlet & Violet Expansion Pack “Black Bolt” Box

Market Trend Chart

Price In January	Current Price	Increase Rate
¥12,093 JPY	¥22,825 JPY	88.7%

The counterpart to White Flare, featuring Zekrom ex BWR. A standout is the Seismitoad AR illustrated by the legendary Shinji Kanda, whose surrealist style has a cult following in the US. This “artist-driven” demand is helping the box maintain a high floor price despite previous restocks.

#8. Sun & Moon Expansion Pack “Miracle Twin” Box

Market Trend Chart

Price In January	Current Price	Increase Rate
¥108,000 JPY	¥196,999 JPY	82.4%

Home to the iconic Mewtwo & Mew GX TAG TEAM. Its “Perfection” ability made it a competitive staple, but its “Alternate Art” (SA) showing the two legends back-to-back has made it a legendary collector’s piece. Now approaching the 200,000 JPY mark, it’s becoming a true blue-chip asset.

#9. Sword & Shield Enhanced Expansion Pack Pokémon GO Box

Market Trend Chart

Price In January	Current Price	Increase Rate
¥11,500 JPY	¥20,333 JPY	76.8%

A unique collaboration featuring photorealistic art that blurs the line between the game and reality. The Mewtwo V Alt Art—depicting Mewtwo descending upon a darkened city—resonates deeply with fans of the mobile app. The “real-world” aesthetic provides a refreshing vibe that stands out from traditional TCG art.

#10. Scarlet & Violet Expansion Pack “Glory of Team Rocket” Box

Market Trend Chart

Price In January	Current Price	Increase Rate
¥14,073 JPY	¥24,860 JPY	76.7%

A dark, edgy tribute to the most iconic villainous team. The Team Rocket’s Mewtwo ex SAR is the primary driver here. For the 30th anniversary, many “OG” fans are returning to the hobby, and nothing says “classic Pokémon” like the menacing aesthetic of Team Rocket.
