Your Mobile Lease Didn't Protect You, It Just Delayed the Bill
リースは価格変動をなくすのではなく、更新時の見積もりに移しているだけです。
Most large organizations in Japan moved corporate mobile fleets to leasing years ago, on the reasonable assumption that it would insulate the budget from hardware price swings. It didn't. It just moved the volatility from a one-time purchase decision into a renewal number that's now starting to climb, because the device sitting underneath that lease has gotten meaningfully more expensive to build.
Apple is now passing memory and component cost increases directly into phone pricing after years of holding US prices relatively steady, and its own leadership has pointed to unprecedented inflation in memory and storage costs as the driver. The iPhone 18 Pro and Pro Max launched in September at $1,199 and $1,299 in the US, each $100 above its predecessor, and at ¥219,800 and ¥239,800 in Japan. The increase didn't stop with the new models. Apple raised the price of every iPhone it kept selling, taking the iPhone 17 from $799 to $899 in the US. In Japan it was the second increase of the year, after one in July, and it lifted the iPhone 17 from ¥142,800 to ¥159,800. Even the cheapest new iPhone Apple sells there, the iPhone 17e, now costs ¥124,800. That second Japan increase arrived after the yen had already recovered from its July low, which fits the pattern that vendor price lists reset on their own schedule and don't follow the exchange rate day to day. There is also no standard iPhone 18 this cycle, so anyone buying before spring 2027 is choosing between a more expensive current-generation phone and a Pro that starts at ¥219,800.
Google's Pixel line makes the currency mechanism easier to see. The base Pixel model's Japan price climbed from ¥74,800 for the Pixel 5 in 2020 to ¥128,900 for the Pixel 9 in 2024, an increase of roughly 70% in four years, and much of that climb was currency, not hardware. Between the Pixel 7 and Pixel 8 alone, Google's US price rose by only $100, while the Japan price jumped nearly 40%, because the yen moved from around ¥125 to ¥145 per dollar in that same window. The device barely changed. The exchange rate did most of the work.
The newest generation shows what it looks like when a vendor chooses not to pass that through. The Pixel 11 launched in Japan in August at ¥136,800, 6% above the Pixel 10's launch price, but only because Google dropped the 128GB tier and made 256GB the starting point. Compared at the same 256GB capacity, it is about ¥7,000 cheaper than the Pixel 10 was, while the US price stayed at $899. With Japan's consumption tax stripped out, the yen price works out to an exchange rate of about ¥138 to the dollar, well below where the yen actually trades. Google is absorbing part of the currency gap in a market its regional director called the most important one for Pixel, in what she described as a very difficult year. It hasn't done this across the whole lineup. The Pixel 11 Pro XL costs ¥14,900 more than its predecessor, and the Pixel 10a was raised by ¥12,900 mid-cycle as memory costs climbed.
In Japan specifically, corporate mobile fleets are overwhelmingly standardized on iPhone or Pixel because of how each manufacturer supports enterprise device management. That leaves IT leaders here with less room to simply shop around for a cheaper device brand the way they might with Windows laptops, where the vendor field is much wider. Within that two-vendor field, though, the gap has opened up: at the same 256GB starting capacity, the base Pixel 11 lists at ¥136,800 against ¥159,800 for the base iPhone 17.
Here's the part worth saying plainly: a lease price is a function of the underlying device cost, the financing terms, and the residual value assumption. When the device itself gets more expensive to manufacture, that cost shows up in your next renewal quote whether you bought outright or leased. Leasing smooths cash flow and shifts residual-value risk to the leasing company, which are genuinely useful things, but it was never a hedge against the hardware itself becoming more expensive. For a lot of IT budgets, that distinction got lost somewhere along the way.
Layered on top of this is a structural shift in how Japan's carrier market works. A revision to the Telecommunications Business Act that took effect in 2019 required carriers to stop bundling deep device discounts into service contracts, the practice that used to make the "zero yen phone" possible. Since then, the market has settled into roughly three tiers: full contracts with the major carriers, which come with the fullest set of network features and priority access to newer capabilities as they roll out; carrier-owned budget sub-brands such as ahamo, povo, and LINEMO at a lower monthly cost; and third-party MVNOs at the lowest monthly cost of all. The device price itself, though, is now largely the same across all three tiers, since the discount-cap reform saw to that. The "cheaper" tiers save you money on the service plan, not on the device driving most of the increase in the first place. Feature parity between tiers, particularly newer network capabilities like 5G SA, varies by carrier and is still evolving, so it's worth confirming the current specifics for whichever carriers your fleet uses before treating that gap as fixed.
A few things follow for anyone managing a mobile fleet here. Lease renewals need to be budgeted as a variable cost, not a flat one. If your forecasting still treats mobile lease costs as steady year over year, that assumption needs updating alongside your laptop refresh budget. The device decision and the plan decision are now genuinely separate line items, since device discounting is off the table industry-wide, and both are worth modeling as moving numbers instead of one bundled figure. It's also worth revisiting device standardization policy. If your MDM and security requirements allow it, check whether the fleet needs to stay this narrowly standardized on flagship-tier iPhone or Pixel models, or whether lower-tier configurations meet the actual need for a meaningful share of users. Enterprise buyers should also push for enterprise-specific carrier terms directly, since corporate bulk agreements are a different conversation from the consumer sub-brand market.
The pattern running through this whole series shows up here too. A channel that looked "handled" (leasing, or the budget carrier tier) carries the same underlying cost pressure as everything else, just one layer removed from where you'd expect to see it.
