Instant Exchanges, Mega-Value Assets—Inside the Financial Revolution of Japan Post’s Digital Currency

Drastically Lower Fees! Overseas Transfers Can Be Done In an Instant

Electronic money such as Suica and PayPay has already become an indispensable part of our daily lives. But in the world of finance, a next revolution is already underway: digital currency.

“If you think this is just another sketchy cryptocurrency story,” that’s a misunderstanding.

The turning point came from none other than Japan Post Bank. Last September, the bank announced it was exploring tokenized deposits using blockchain technology—highlighting that this system is separate from speculative cryptocurrencies like Bitcoin and could become a true infrastructure for daily life.

So how is this different from already popular e-money or volatile crypto assets? The digital currency poised to change bank transfers, real estate transactions, and even what’s in our wallets is finally being revealed.

Masato Matsushima, a cryptocurrency analyst at Monex Securities, explains the benefits of a society where digital currency is fully implemented:

“Domestic bank transfers are convenient, but overseas remittances are a different story. Currently, it’s cumbersome, takes days for funds to arrive, and the fees are significant. Individuals who frequently engage in global transactions may still be limited, but with digital currency, overseas transfers could be as instant and low-cost as domestic transfers.”

Currently, when sending money from Bank A to Bank B, consumers only see the front-end process on their smartphones, but behind the scenes, multiple parties are involved, which costs a lot of money and time.

Yuki Fukumoto, head of the Financial Research Department at Nissay Research Institute, notes that even for electronic money like Suica, the back-end settlement still involves transfers between business accounts, which incur both costs and time.

Digital currency, on the other hand, dramatically simplifies this back-end processing digitally. As a result, immediate settlement becomes possible and fees drop drastically.

Buying 100 Million Yen Real Estate as Easily as a Pokémon Card

The innovation of digital currency goes beyond just making transfers more convenient.

In the future, not only bank deposits but also stocks, bonds, real estate, and even high-value assets—like Pokémon cards traded at high prices—could be instantly exchanged on a digital shared ledger (blockchain).

For example, if someone owns 100 million yen worth of stocks and wants to buy real estate worth the same amount, the current process involves complicated procedures and fees for selling the stocks and purchasing property.

With digital currency, all of this could be handled on a common digital ledger, allowing instant exchanges at minimal cost. In the future, even cumbersome property registration procedures could potentially be completed instantly within the system.

Matsushima predicts this tokenized future:

“Currently, assets are managed separately—deposits by banks, stocks by securities firms, real estate by management companies. But in the future, all of these could be tokens aggregated on a blockchain. Once on the same ledger, even different types of assets could be directly traded digitally.”

Fukumoto from Nissay Research Institute also points out that the spread of digital currency will expand the handling of valuable assets, such as artwork.

A Safety Difference That Sets It Apart from Bitcoin

This raises the question: “How is this different from cryptocurrencies like Bitcoin?”

Both use blockchain technology to record transactions. Blockchain compresses and transforms transaction data using cryptographic techniques called hash functions and links them like a chain. Even a small alteration to past data breaks the integrity of the chain, making tampering virtually impossible. This high level of security forms the foundation of digital currencies.

However, a crucial difference lies in whether there is a backing asset.

Cryptocurrencies (Bitcoin, etc.): No backing asset exists, so prices fluctuate wildly, making them impractical for everyday payments.

Digital currencies: They are backed by assets like bank deposits, giving them stable value.

Currently, central banks such as the Bank of Japan are moving toward implementation, while private companies are developing stablecoins, digital currencies backed by deposits. Japan Post Bank’s initiative is similarly aiming to digitize (tokenize) deposits into digital assets.

Suica and PASMO are merely prepaid systems and cannot, in principle, be refunded in cash. In contrast, digital currencies function like bank deposits and can be converted back into cash, serving as a means of value exchange.

Consumers may not notice the changes behind the scenes of payments. Yet, once digital currencies are fully implemented, the dramatic reduction in costs for financial institutions and businesses could translate into lower fees and new services, benefiting consumers directly.

With the transformation of the very form of money, the way we handle real estate, high-value items, and even daily payments could be fundamentally reshaped—and that day may not be far off.
