When full-service brokers and advisers add value, the cost and conflict-of-interest issues, and what to demand.
Full-service brokers (Nomura, Daiwa, SMBC Nikko, Mizuho) and advisers can help with bonds, IPOs, inheritance, and complex situations, but cost more and may face distribution conflicts — demand explicit all-in costs and benchmark comparisons.
Full-service brokers — Nomura, Daiwa, SMBC Nikko, Mizuho — and human advisers can genuinely help in specific situations: navigating bonds and IPO allocations, inheritance and estate matters, cross-border complexity, or simply providing hand-holding and physical branch support that some investors value. For complex or high-net-worth needs, that service can be worth paying for.
The trade-off is cost. Branch and comprehensive-course commissions can be dramatically higher than online brokers — for routine domestic stock trades, branch schedules can reach well over 1%, versus near-zero online. For simple passive investing, that gap is hard to justify.
Do not assume adviser compensation is neutral. When an adviser or firm earns more by selling certain products, there is an inherent conflict of interest, and a recommendation may reflect distribution incentives as well as your interests. This does not make advice worthless, but it means you should scrutinise recommendations rather than accept them on trust.
The practical safeguard: for any recommendation, demand the explicit all-in cost (commissions, wrap or advisory fees, fund expenses, and any hidden charges) and a comparison against a relevant low-cost benchmark. If a recommended product cannot justify its cost against a cheap index alternative, ask why. Good advisers welcome these questions.

This is education, not a recommendation. Most beginners research low-cost, broadly diversified index funds — for example all-country (全世界株式) or S&P 500 trackers — rather than picking individual stocks, because low fees and diversification are within your control while returns are not. Understand that values fall as well as rise, match the risk to your time horizon, and never invest money you may need soon.
