Gyakuten Bariba Reverse Singapore Guide: How to Play, OX Values and Where to Buy Exclusive Bariba Coins from Japan

Gyakuten Bariba Reverse Exclusive Coins: Binder, Guaranteed-BBR Coin Sets and the Gold BKR Special Edition, Bought from Japan via Proxy Shopping

Key points
• Gyakuten Bariba Reverse (逆転バリバリバース) is Bandai’s flip-to-win coin battle toy. The binder, the 3-coin sets, the special-edition manga and the battle field all come with fixed exclusive or rare coins, and none of them is easy to find in Singapore
• The binder with an exclusive BR coin sells for ¥1,600 (about S$13) at Yodobashi in Japan, below its ¥2,200 list price
• Sold-out items such as the special edition, and single rare coins, can be found on Mercari, Japan’s largest second-hand marketplace
• Buy&Ship proxy shopping lets you paste a Yodobashi, Rakuten or Mercari link and pay in Singapore dollars, with shipping to Singapore from S$9 for the first pound

Gyakuten Bariba Reverse launched in Japan in March 2026, and according to a press release published on PR TIMES the first wave of Bariba Coins, about 100,000 units, sold out in roughly a month. Each Bariba Coin is double-sided: you flick your coin into your opponent’s, and if theirs flips over, you win. All you need is a flat table.

The coins are sold in blind packs at ¥396 each in Japan, but the items collectors want most are the ones with fixed coins: the binder and the battle field each include coins you cannot get anywhere else, the 3-coin sets guarantee a BBR rare, and the first manga volume came with two gold coins. We could not find the series at Singapore toy retailers such as Toys”R”Us Singapore as of 27 October 2026, so Japan is where to look.

The simplest way to buy from Japanese stores is Buy&Ship proxy shopping: send us the product link, we place the order in Japan, and you pay in Singapore dollars. If you already shop on Amazon Japan yourself, you can also ship to the Buy&Ship Japan warehouse and forward the parcel to Singapore.

Buying Gyakuten Bariba Reverse from Japan: Proxy Shopping and Japan Warehouse Forwarding

Bandai’s Japanese list prices are ¥396 for a blind pack, ¥1,210 for a 3-coin set and ¥4,950 for the battle field. Bandai’s official online store, Premium Bandai, does not sell the series. The stores selling at or below list price are mainly Japanese electronics retailers such as Yodobashi, and Rakuten Ichiba shops such as EDION. Sold-out items, like the special edition and single rare coins, turn up on Mercari. These sites are built for customers in Japan, and some do not open outside Japan at all, which makes them hard to order from directly; Buy&Ship proxy shopping can buy from them for you.

Paste the product link into the proxy shopping order page and we place the order in Japan. Costs are shown in Singapore dollars. Once the item reaches the Buy&Ship Japan warehouse, you can combine it with your other Japanese parcels and ship everything to Singapore, charged by weight.

Amazon Japan also sells Gyakuten Bariba Reverse, and you can order there yourself and ship to the Buy&Ship Japan warehouse. Most listings are from third-party sellers who charge above list price, though: on 27 October 2026 a single Vol. 4 pack was listed at around ¥990, more than double the ¥396 list price. Compare with the list price before you buy; the two methods are compared in Proxy shopping or forwarding.

What is Gyakuten Bariba Reverse? How to Play, OX Values and the Three Battle Rules

The world of Gyakuten Bariba Reverse is built around creatures called Baribii (バリビィ). Each has two forms: the front “Order Side” and the reverse “Xtreme Side”, marked O and X after the character’s name. Alongside the toy there is a manga serialised in Monthly CoroCoro Comic and an official YouTube anime. Vol. 1 of the coins went on sale in Japan on 21 March 2026, and Vol. 4 had followed by October.

To play, you flick your own coin into your opponent’s. There are three levels of rules:

• Beginner rule: one coin each. Flip your opponent’s coin over and you win.
• Standard rule: adds the OX value printed on each coin. If the coin you hit does not flip, compare the two OX values; if the attacker’s is higher, the opponent’s coin is knocked out. Knock out all of your opponent’s coins to win.
• Expert rule: three coins each, and the three OX values together must not exceed 15,000, so team building matters.

From Vol. 3, “Meta” coins (メタ化) have different OX values on each side, which adds more tactics.

4 Must-Buy Gyakuten Bariba Reverse Items from Japan: Exclusive BR, BBR and Gold BKR Coins

Each of these comes with fixed exclusive or rare coins, so there is no blind-pack luck involved, and none of them is easy to find in Singapore. Store prices are as of 27 October 2026, converted to Singapore dollars at that day’s rate.

Looking for a specific rare coin? Search Mercari for singles

Mercari is Japan’s largest second-hand marketplace, and many collectors sell the coins they pulled from packs, one by one or in small sets. If you want a particular RR or BBR coin, search Mercari for “バリバコイン” plus the character name or rarity (for example “バリバコイン BBR“); it is often faster and cheaper than opening boxes. Buy&Ship has a Mercari proxy shopping service for Singapore, so you can send us the item link. Check the item condition and the seller’s ratings before ordering.

Prices as of 27 October 2026, converted at ¥1 = S$0.00813 for reference only. Store prices, Mercari listings and stock change quickly; the price shown when you order applies. Singapore dollar figures exclude Japanese domestic delivery, the proxy shopping service fee and international shipping.

How Much Does It Cost to Ship Gyakuten Bariba Reverse to Singapore? A Combined Shipment Example

Take an XTREME SIDE binder (Yodobashi, ¥1,600), a 3-coin set (Amazon Japan, about ¥1,240) and the manga special edition (Mercari, about ¥3,600): that is one BR, one BBR and two gold BKR coins, for ¥6,440 in total. The three items come from three websites, so they are three separate proxy shopping orders; once they reach the Japan warehouse, they are combined into one shipment to Singapore.

Item	Amount
Items (¥6,440)	About S$52
Japanese domestic delivery	Charged per store; shown on your order page
Proxy shopping service fee	Based on the item price; shown on your order page
International shipping (assumed 3 lb after packing, Buy&Ship Shipping: S$9 first lb + S$7 per additional lb)	S$23
Total at the base shipping rate (before Japanese delivery and service fee)	About S$75

Shipping from the Buy&Ship Japan warehouse to Singapore is charged by weight. Buy&Ship Shipping is S$9 for the first pound and S$7 for each additional pound. A UPS option is also listed on the shipping rates page. See the shipping rates page for the latest prices.

Saving tip: coins, binders and books are light, so shipping one or two items on their own is poor value. Combine coin sets, binders, the special edition and your other Japanese parcels into one shipment and you pay on the combined weight.

Proxy Shopping or Forwarding: Which Suits You?

For most readers, proxy shopping is easier: the Japanese stores selling at or below list price are built for customers in Japan, while proxy shopping lets you simply submit their product links. If you already have an Amazon Japan account and the Amazon price is reasonable (as with the 3-coin sets), ordering yourself and shipping to the Japan warehouse saves the proxy shopping service fee.

	Proxy shopping	Amazon Japan yourself + Japan warehouse forwarding
Who places the order	Buy&Ship orders for you	You order on Amazon Japan
Where you can buy	Product links from Japanese sites such as Yodobashi, Rakuten Ichiba, Mercari and Amazon Japan	Amazon Japan only; many items are sold by third-party sellers above list price
Payment	In Singapore dollars	In yen on Amazon Japan
Costs	Item + Japanese delivery + service fee + international shipping	Item + Japanese delivery + international shipping

Either way, your items arrive at the Buy&Ship Japan warehouse first and are shipped to Singapore by weight, and they can be combined with parcels from other Japanese stores.

What to Check Before Buying Gyakuten Bariba Reverse

Compare prices before you buy

On 27 October 2026, third-party sellers on Amazon Japan were asking from ¥16,000 for a box of Vol. 4, more than 30% above the ¥11,880 list price, and from ¥6,770 for the 2WAY battle field, nearly 40% above its ¥4,950 list price. The same item can vary a lot between stores and Mercari, so compare first.

Blind packs are random; sets give you fixed coins

Each pack contains one random coin, Bandai does not guarantee a full set from a box of 30, and rare coins such as RR are harder to pull. If you want a particular character, the 3-coin sets, the binder and the battle field all come with fixed coins.

Check Japanese release dates for pre-orders

The 2WAY battle field goes on sale in Japan on 14 November, and stores ship after release. Pre-orders have closed at Kojima.net, Yodobashi and amiami; when you submit a proxy shopping order, availability is confirmed on your order page.

Check the restricted items list before shipping

Each overseas warehouse has its own restricted items list. Please check Buy&Ship’s restricted items page to make sure your items can be shipped before you order.

Gyakuten Bariba Reverse Proxy Shopping FAQ

Can I buy Gyakuten Bariba Reverse in Singapore?

A: As of 27 October 2026 we could not find the series at Singapore toy retailers such as Toys”R”Us Singapore. The binder, battle field, 3-coin sets and special-edition manga with their fixed exclusive coins are Japanese releases, so buying from Japanese stores, or Mercari for sold-out items, is the most reliable route.

Should I buy blind packs from Japan?

A: Blind packs are ¥396 at list price in Japan, but list-price stores sell out quickly and resellers on Rakuten and Amazon Japan were asking from around ¥596 to ¥990 a pack on 27 October. If you are after particular characters, the 3-coin sets or single coins on Mercari are usually better value than packs.

What are the different waves, and what are they called?

A: As of October 2026, Japan has released Vol. 1 (秩序を統べる者たち / 自由を求める者たち), Vol. 2 (表裏を司る者たち), Vol. 3 (最強を誇る者たち / 最凶を貪る者たち) and Vol. 4 (真実を守る者たち / 真実を奪う者たち). English names vary between sellers, so the Japanese product name is the most reliable way to check you have the right item.

Can I ship several Gyakuten Bariba Reverse items to Singapore together?

A: Yes. Items in the same proxy shopping order arrive at the Japan warehouse together, and parcels from other orders or other Japanese stores can be combined into one shipment, charged on the combined weight.
