As Japan's New NISA enters its second year in 2025 — having launched in January 2024 — attention is increasingly on how to use the growth investment allocation. With the dramatically expanded tax-free quota of ¥2.4M per year and ¥12M lifetime, how you use it will significantly affect your long-term wealth-building results. This article covers the optimal strategy for using the growth allocation in light of the 2025 market environment, explained in beginner-friendly terms.

Key Points for the Growth Allocation in 2025
The design of New NISA itself hasn't changed from 2024, but there are several operational points to keep in mind in 2025.
First, even if you didn't fully use your growth allocation in 2024, unused capacity cannot be carried over into the following year. The annual quota resets every January, so making a plan to use it up systematically matters.
Also, 2025 is shaping up as a period of heightened market uncertainty driven by U.S. tariff policy and the BoJ's rate-hike trajectory. When investing in risk assets through the growth allocation, time diversification often handles volatility better than a single-year lump-sum approach.
- The growth allocation and the tsumitate (regular savings) allocation can be used together (up to ¥3.6M per year combined)
- Even after you sell, the lifetime cap is recoverable in subsequent years (based on purchase amount)
- The growth allocation supports a wide range of products: individual stocks, ETFs, mutual funds, and REITs
- Monthly contributions are also possible — splitting use between the growth and tsumitate allocations is key
2025 Recommended Sector Analysis
When using individual stocks or sector ETFs in the growth allocation, knowing which sectors are promising matters. Below is an outlook on the main sectors in light of the 2025 market environment.
With the spread of generative AI driving expanded data-center investment, semiconductor demand is expected to remain robust over the medium to long term. Domestically in Japan, companies benefiting from AI-related capex are drawing increasing attention. That said, watch out for U.S.–China tech-regulation risk and elevated share prices.
Growth-allocation use case: semiconductor-related domestic ETFs or global technology-sector index funds are among the choices to consider.
Backed by the Tokyo Stock Exchange's "P/B below 1.0x" improvement requests, Japanese companies have been raising dividends and buying back shares in succession. NISA's tax-free benefit applies to dividends as well, making high-dividend stocks an especially good fit for the growth allocation.
Focusing on domestic-demand defensive sectors like financials, trading houses, and infrastructure — companies with a track record of consecutive dividend increases offer stability for medium-to-long-term holding. A BoJ rate-hike phase could also be a tailwind for the banking sector.
In Japan with its aging population, demand for medical and elder-care services is expected to grow structurally. Globally, AI-driven drug discovery and biotechnology advances are drawing attention, and the sector also has defensive characteristics less affected by the business cycle.
Using a medical/healthcare-sector ETF rather than individual stocks lets you get thematic exposure while limiting single-name risk.

|---|---|---|---|
| U.S. growth stocks / technology | 50% | NASDAQ-tracking ETFs, etc. | High return potential, high volatility |
| Domestic growth stocks | 30% | Growth / small- and mid-cap stocks | Concentrated bet on domestic growth firms |
| Healthcare / AI-related | 20% | Thematic ETFs | A bet on medium-to-long-term themes |
Risk Management Essentials
While the growth allocation has the powerful benefit of being tax-free, note that even if performance deteriorates, losses cannot be offset against gains in other accounts. Use the risk-management ideas below as a reference.
Many individual investors use the tsumitate (regular savings) allocation for core assets (global equity, S&P 500 index, etc.) on a monthly contribution basis, and use the growth allocation for the more "offensive" parts — individual stocks, ETFs, REITs, and thematic funds. With up to ¥3.6M per year across both, a deliberate split is the key to wealth building.
