## Survey Overview
Survey Date: February 24, 2026
Survey Method: Internet survey
Target Audience: Men and women residing in Japan (with experience using overseas exchanges)
Valid Responses: 234 people
Implementing Organization: Clabo Inc.
## Survey Content
## 75% have experience using overseas exchanges, with active generations being the mainstream
### High utilization rate: 3 out of 4 have experience
We conducted a detailed survey on the usage of overseas exchanges among 312 users who have experience with cryptocurrency transactions.
As a result, 234 people, or 75% of the total, responded that they "have used" overseas exchanges, indicating a very high penetration rate.
In particular, 47.4% of respondents stated that they "are currently using" overseas exchanges, highlighting a profile of holders who utilize overseas platforms as a regular place for transactions, not just domestic ones.
On the other hand, only 25.0% responded that they "have never used" overseas exchanges, revealing that three out of four experienced investors have accessed global markets at least once.
Overseas exchanges offer attractive options for holders, such as a variety of altcoins not available domestically, high-performance charts, and flexible leverage settings.
It is believed that holders with more advanced research capabilities tend to actively prefer overseas platforms that are closer to the source of information.
### Widespread penetration from younger to working generations
Looking at age-group data, the 30s recorded the highest number of "currently using" responses with 47 people across all age groups.
This was followed by the 40s with 36 people and the 20s with 33 people, clearly indicating that the working generations from their 20s to 40s are the main players in overseas exchanges.
This generation is quick to adapt to digital technology and is presumed to be flexible in dealing with overseas service interfaces, which are primarily in English.
Meanwhile, even among those aged 50 and above, the proportion of users with experience is not low, suggesting a trend of incorporating overseas exchanges into their portfolios as part of asset management.
The environment where the latest overseas trends and information on specific assets are instantly disseminated through social media and video platforms is likely a major factor supporting the high utilization rate, especially among younger generations.
The shared understanding across generations that the speed of information acquisition determines investment success may be increasing interest in overseas platforms.
### Continued use prominent among those with annual incomes of 4 million JPY or more
Analyzing usage by individual annual income, it became clear that a wide range of income brackets, from less than 2 million JPY to the 6 million JPY range, are actively trading on overseas exchanges.
Particularly noteworthy is the 4 million to 6 million JPY income bracket, where a high percentage of respondents indicated "currently using," confirming continuous usage.
While cryptocurrency was once perceived as an investment for specific wealthy individuals, it is now evident that individuals with general income levels are the core supporters of the market.
Among high-income earners exceeding 10 million JPY annually, although the absolute sample size is small, most are currently using overseas exchanges.
Their stance on asset preservation and maximizing profit opportunities is prominent, suggesting a strategic utilization of overseas exchanges.
Cryptocurrency allows access to assets worldwide with small amounts, enabling diverse investment strategies tailored to individual risk tolerance, regardless of income level, which is driving its widespread adoption.
### Overseas platform utilization progresses regardless of gender
Cross-tabulation by gender revealed that 47.8% of men and 46.7% of women "are currently using" overseas exchanges.
This balanced figure clearly indicates that there are almost no gender-based barriers to entry or differences in preference for using overseas exchanges.
While the cryptocurrency sphere was once a male-dominated field, the maturation of communities and the democratization of information have led to a remarkable increase in female holders.
The proportion of those who "have never used" overseas exchanges is also slightly lower for women (21.5%) compared to men (26.8%).
This shows that gender does not influence holders' attitudes toward choosing a global trading environment on their own initiative.
The widespread availability of reliable specialized media and social media, allowing everyone equal access to advanced trading environments, must be the background to such utilization rates.
The diversification of market participants is expected to bring multi-faceted perspectives to the cryptocurrency ecosystem and contribute to healthier market formation.
## "Intentional non-declaration" by 20% highlights lack of understanding of the system
### Only 30% declare all profits in profitable years
Among 234 holders who made profits using overseas exchanges, only 31.6% reported correctly declaring all profits.
The most common response was "declared only in some years" at 34.6%, highlighting the difficulty of continuous declaration.
Furthermore, 18.8% of respondents "did not declare" despite knowing it was necessary, revealing a serious reality where approximately one in five individuals are intentionally undeclared.
Including the 8.1% who answered "did not know," it is clear that many users are not fully fulfilling their tax obligations.
Even for overseas exchanges, Japanese residents are obligated to pay taxes on profits earned, as clearly stated in the National Tax Agency's guidelines.
As the cryptocurrency market expands, individuals' tax compliance awareness and understanding of the system have not kept pace, which appears to be a factor contributing to the undeclared population.
### Over 40% misunderstand the treatment of overseas exchanges compared to domestic ones
When asked about the reasons for their declaration status, the most frequent response was "thought the treatment was different from domestic exchanges" at 42.3%.
Domestic cryptocurrency exchange operators are under Japanese legal regulations, and the provision of transaction history is standardized, but it is clear that a very large number of holders perceive overseas platforms as something different.
Additionally, 39.3% of users stated that they "could not judge due to lack of information," indicating significant confusion regarding calculation rules and tax treatment specific to overseas exchanges.
More than 30% also responded that they underestimated their profit amounts, suggesting the possibility that a mistaken interpretation that small amounts do not require declaration is widespread.
In reality, for individuals with salary income, a final tax return is required if side income, including cryptocurrency, exceeds 200,000 JPY annually.
Only 26.5% correctly understood that they were subject to declaration, indicating an urgent need for the dissemination of correct information.
### Undeclared group concentrated in 30s and 40s
In the cross-tabulation by age group, 16 people in their 30s and 14 people in their 40s answered "knowingly undeclared," significantly outnumbering other age groups.
This group is an active holder demographic with a high utilization rate of overseas exchanges, but it is also revealed to be the group with the highest tax risk.
High trading frequency and the tendency for calculations to become complex are also considered psychological hurdles that deter declaration.
In contrast, the proportion of "declared only in part" is higher among those in their 20s, suggesting an attitude of attempting to declare, albeit incompletely.
Furthermore, among those aged 50 and above, the proportion of "unable to judge" or "did not know" tends to be higher than among younger generations, indicating that knowledge gaps may directly impede declaration behavior.
Considering one's career and social credibility, working generations should avoid the risk of being pointed out by tax authorities, and an update of accurate knowledge is required.
### Non-declaration concentrated in income brackets below 8 million JPY
Analysis by annual income also shows that "knowingly undeclared" responses are concentrated in income brackets below 8 million JPY.
Most high-income holders with annual incomes exceeding 10 million JPY have completed their declarations, indicating a high awareness of asset management.
On the other hand, among middle to low-income groups, the perception that the cost of hiring an expert for calculations is not worthwhile, or the difficulty of calculating independently, is presumed to be a contributing factor to non-declaration.
Particularly in the income bracket of less than 2 million JPY to 4 million JPY, partial declarations and non-declarations are noticeable, revealing a struggle to maintain tax compliance.
When using overseas exchanges, administrative burdens such as JPY conversion and offsetting profits and losses with domestic exchanges are by no means light.
However, taxation is a civic duty, and proper declaration is essential regardless of income level.
The use of simple calculation tools and information organization will be key to improving the declaration rate in this group.
### 30% of holders struggle repeatedly, not just once
A survey on "experience of hesitation" regarding profit declaration from overseas exchanges revealed that a remarkable 82.0% of users felt some kind of hesitation.
"Hesitated once" accounted for 52.1%, and "hesitated many times" for 29.9%, highlighting a situation where doubts are continuously unresolved as transactions accumulate.
Only 12.8% of respondents stated that they "have never hesitated," making it no exaggeration to say that almost all holders using overseas exchanges encounter the barrier of taxation.
The fact that nearly 30% responded that they hesitate many times symbolizes how difficult the profit calculation and declaration methods for overseas exchanges are.
Annual legal revisions and the emergence of new transaction forms such as DeFi and NFTs, which quickly render existing knowledge obsolete, are also contributing factors.
To enable holders to continue trading with peace of mind, reliable and specific guidelines and support systems that can dispel such "hesitations" are considered indispensable.

Do profits from overseas exchanges also need to be declared?
Yes, if you are a resident of Japan, profits from cryptocurrency on overseas exchanges are subject to tax obligations, just like domestic exchanges. This is clearly stated in the National Tax Agency's guidelines.
Why is declaring profits from overseas exchanges difficult?
Misconceptions about different treatment from domestic exchanges, lack of information, complexity of JPY conversion, and the emergence of new forms like DeFi and NFTs are the main reasons.
Which groups are more likely to under-declare or not declare?
Non-declaration tends to be concentrated among active generations in their 30s and 40s and those with annual incomes below 8 million JPY. Calculation complexity and expert fees are barriers.
