Japanese distributors, camping-car builders, marine traders and storage importers: most China LiFePO4 factories only publish generic English. This page is the Japan B2B sourcing brief — English body with Japanese procurement anchors — for how Japan actually buys: キャンピングカー サブバッテリー, 定置型蓄電池 wholesale/OEM, and 舶用 packs. It follows the same EN+local-anchor pattern as our South Korea page. Research date: November 2026.
Request a Japan quotation / 日本向け見積依頼 — name the use (キャンピングカー / サブバッテリー / 定置型蓄電池 / 舶用 / OEM), voltage platform, capacity and quantity. We do not publish list prices, MOQ or lead times on this page; those are confirmed in writing per project.
Why Japan buys LiFePO4 (import wholesale + channel SKUs)
Macro (low institutional friction in the Muse Top20 set) explains inbound trust fit — it does not by itself prove a SKU. Live Japanese importer and channel language points to:
- 蓄電池の輸入卸 — Japan-based traders who import secondary batteries from China and sell wholesale to power-equipment makers and installers; technical support and after-sales are part of the channel story.
- キャンピングカー電装 / サブバッテリー — camping-car builder supply: 12 V / 24 V LiFePO4 house banks (サブバッテリー), often with heat function or Bluetooth called out on JP catalogue cards. Do not RFQ as US “RV”.
- 定置型蓄電池 — stationary storage modules for off-grid sites, disaster backup and C&I projects; inverter / PCS protocol is project-specific.
- 舶用蓄電池 — marine traders list lithium packs for ship/boat use; compliance and form factor are named per vessel class — confirmed in the quote, never as a catalogue-wide claim.
Local vocabulary (Japanese anchors)
| Avoid (EN calque) | Use with JP buyers |
|---|---|
| battery (only) / “lithium” | リン酸鉄リチウム / LiFePO4 / LFP + 蓄電池 or バッテリー by channel |
| RV battery | キャンピングカー サブバッテリー |
| home battery rebate copy | 定置型蓄電池 / project ESS — name PCS brand if known |
| marine battery (vague) | 舶用蓄電池 + vessel / duty cycle |
| Blanket factory-cert marketing lines | 機種ごとの書類（UN38.3 / 商業インボイス等）— confirmed per model |
| price list on page | 見積 after written spec |
Product families (patterns only)
- 12 / 24 V deep-cycle for キャンピングカー and leisure — 12 V series, 24 V series, leisure solutions.
- 定置型 / rack ESS — energy-storage series and rack-ESS selection guide.
- Marine — marine solutions.
- OEM / ODM / private label — OEM/ODM; freeze the written 仕様 before tooling talk.
- Wholesale — distributor programme.
Import and documents (confirmed per shipment)
Japan import of lithium batteries involves transport rules and importer paperwork that we do not invent as rates or permit names on this page. Before deposit, agree in writing at least: UN38.3 test summary for transport, commercial invoice / packing list with model numbers, and the data your forwarder or Japanese importer needs. Model certificates required for a given channel (e.g. vessel class, stationary install) are confirmed per model — never as a catalogue-wide claim.

FAQ
Why is this page in English? Japan China-sourcing desks often open RFQs in English; Japanese anchors above keep vocabulary local. A full Japanese-language page can be briefed separately if GSC/inquiry data justify it.
キャンピングカー and 定置型 — same RFQ? List both if needed, but treat them as different channels (form factor, BMS profile, documents).
Do you publish prices or MOQ? No. Confirmed only in a written 見積.
