RetireJapan

Thanks adamu and RJ. Yeah, the amount needed is surplus to what we can put in from monthly regular income.

2 is it? Hmm. I'm wondering what will happen if the market gradually drops in the next four years, due to the economy, geopolitics or exchange rates. Surely we wouldn't have enough to fill the NISA and we wouldn't be able to buy stocks cheap because there's no spare cash? But I suppose the chance of that happening is less than chance of it going up, which is why you chose number 2?

I do like the idea of drip-feeding it automatically every month though

If the market drops while you are drip feeding from a taxable account, more taxable funds will get put into the NISA faster, and if prices then recover, the larger amount will be tax protected.

I think you are dealing with the lump sum vs. DCA dilemma, it's not really a NISA question:

The only twist for NISA is you have to drip feed the Tsumitate portion for ¥100k/mo. You can choose to drip feed the Growth portion at ¥200k/mo or lump sum ¥2.4M annually.

In a taxable account dump the lump sum into something like eMAXIS Developed Markets Bond fund.

Sell it off as you need to over four years to fund NISA purchases in tsumitate fashion.

The bond fund is not as risky as equities, but it’ll probably do better than leaving it in cash, even with Japanese interest rates having risen a little - still well below the rate of Japanese inflation.

The above is not my original idea - I read about it in a book by 朝倉智也, about how to go about living in the current age of inflation.

If you go for growth in taxable account that’s fine too, but if you want to avoid a drawdown due to unfortunate timing then the international bond fund is less likely to suffer that fate, while giving more protection of value in the interim. (There is a possibility that the currency could go against you, but history would suggest that’s unlikely, I forget the timeframe used in the book I refer to above but the evidence presented was that people can just go lump sum into a developed market bond fund with any surplus yen and forget about it. Not the case with equities.)

I see what you mean. Since the sell/buy orders are based on cash value and not number of units, we'll be buying more units for the same price. But there's the risk of running out of money before the NISA is filled.

Yes, I suppose it is a "lump sum vs DCA" dilemma in regard to the holding account (taxable). I generally prefer DCA so maybe that's why option 2 is a little worrying to me.

I've since realised that in practice I will only be able to lump sum my taxable account and not my wife's, because I want to avoid gift tax as much as possible. This is the only tax I try to avoid because I strongly disagree with the principle of not sharing assets between husband and wife. So I'll continue to drip feed my wife's NISA with cash. If the tax office gets me then fair enough... but I don't want to make it easy for them.

Unless... (thinking aloud) I put the whole lot in my taxable account, then drip feed both NISAs from there?

Thanks sutebayashi, I'll give this some thought. Initial concern is the fund's value falling due to an increasingly stronger yen and weaker USD, GBP, etc.

Away from keyboard this weekend so I'll get back to this next week. Thanks all.

If you put ¥3.6M in the NISA and it drops to ¥2M, you "filled" the NISA but now it's only worth ¥2M.

If you put ¥3.6M elsewhere, it drops to ¥2M and you move it to the NISA, you didn't fill the NISA, but the end result is the same. Actually it's better because you could theoretically move more taxable assets into the NISA, too (assuming the market always goes up eventually).

Not having enough to fill the NISA shouldn't be a consideration, is what I'm saying. DCA gives you the opportunity to move more taxable assets into the NISA when the prices drop. But you lose the tax protection you would have got by lump summing early if the prices rise.

If the asset types in taxable and NISA are different, then yes you could lose money, or do better but have to pay tax because you didn't put *that* asset in the NISA.

Yep, that’s some of the risk involved with any non-yen investment

I found an extract from the book I was referring to here:
https://diamond.jp/articles/-/323929?ut ... hatgpt.com

It has some data about the types of drawdown observed, with a worst case annual drawdown of less than 4%.

2. Fill the Nisa, use the lump sum tsumitste features as well. Put the rest in a taxable account.

We know lump sum is statistically the best choice, anything else is a behavioral decision.

I might add 5-10% to cash holdings, but I'm strictly equities/cash.
